The 3DSage Game Engine Demo | Download Link 

cool 😎 edit: can't wait to see what people make with your creation, I think its awesome to think that something that you create can spark creativity in others and it sort of becomes its own form of art, keep up the good work.

I really like watching people build 3d engines for older machines. Something about bending the computer to do what it wasn't meant to be doing is magical.

The engine was already impressive; the editor is simply outstanding. That's possibly the most intuitive editor I've seen for that sort of building and you pulled it off on a GBA. Very nice!

9:55 I didn't realize you were editing the game on a Gameboy until you clarified that. Absolutely nuts!

Proud 7.8% percenter

I really like the clean and user-friendly-look of the editor. I fell into the trap of quickly writing an editor before the engine, then just adding features to it... it became a hot mess with too many odd hotkeys. Keep up the amazing work :D

Dedication is off the charts, actually inspiring work being done here

The most valuable creations enable the creativity of others. What a gift! It's like a portable BUILD engine. Just needs some weapons, keys, pickups & enemies to shoot.

I really like how the fake lighting is done, it's really cool how convincing it is!

I fiddled with Hammer & UDB a while ago but have needed a reason to mess with level design again, & this is a very cute reason, looks fun

As someone who's working on their own project with a limited audience, I've been lacking some motivation over the last few weeks. This has been incredibly inspiring. You've done a great job with the user experience and quality of life features. Cheers! Subbed!

The skybox part was mindblowing. You could convince people there was a real DOOM GBA port.

It would be really cool if you could create 2D props, like doom items, props like plants, lampposts, trash cans, cups and bottles.

Man, you're the best! Take your time, it's insanely difficult undertaking and you have to have some time to take care of yourself. We do not want you to burnout and hirt yourself!

Your work continues to impress. MiSTer FPGA runs your demos well also, and has a 2-player core that would probably work with your multiplayer experiments. Looking forward to trying it.

The engine itself is impressive enough just by itself, but the addition of the well-thought-out UI for the level creator really elevates this project to another level. It's easy to see you've thought a lot about creating an easy level-editing experience and intuitive experience (especially considering the limited button count).

As an old gamer who used to play around with modding tools for everything between Wolf3D to Duke3D, this is outright nostalgic!

This needs exposure. I'd love to see it as a part of GB studio somehow. Well done.

It looks absolutely amazing!

Love to see A PC version + tutorial. Fantastic effort, well done!

I gotta tell you, this is making the little kid inside of me go wild! I wanted exactly this kind of thing when I was a kid playing on my GBA! This is awesome! I really wish more devs made stuff like this where it has a focus on ease of use and creation when it comes to any system or computer. This really is very cool. Ive had a GBA with the same flashcart as you sitting around for years and now I have a reason to dig it out! I cant wait to see if we can do stuff like add some FPS style game modes, Im going to have to make some levels regardless. Thank you for your work! It really is very impressive for the tech its on!

I absolutely love how this is turning out. I really love non-euclidean games like antichamber, it would be cool if you can add portals from one sector to another even if those sectors aren't connected on the grid

Been following your work and this project for the past 6 months or so and it is genuinely one of the most impressive feats up optimization I've ever seen, let alone the incredible work you've put into making something functional and snappy that other people are able to utilize as well. For many, this is truly a dream project, and I think it's going to do huge things!

The fact that the editor is IN GAME AND IN REAL TIME is so extremely impressive to me as someone that has been mapping with the Hammer Editor for a while.

The shading individual segments trick is fantastic. About future upgrades, I think if you add dialogue boxes and some predefined 1x1x1 objects (sprites facing the camera, not 3D) that can be moved around in X,Y,Z and interacted as simple triggers of dialogue boxes, you could have very simple games that don't require state machines, or just need very simple flag checks. Like, start the level by a sprite-NPC that sends you on your way to search for X amount of items. You need to explore and navigate optical illusions to get into secret rooms and find the items. Come back to the NPC and get a congratulatory message. I don't know how your custom tile editor works, but you could maybe repurpose it for custom sprites. And obviously a text editor for the dialogue boxes. And you could have people making all sorts of games. Anyway, that's just ideas. I think this project is amazing and your work is inspiring. Thank you

dude. this stuff is absolutely AMAZING. i would love to read a tutorial series where you go through all of the algorithms used in your game, start out with a naiive algorithm written in C, and then show subsequent optimization steps, step by step, so that in the end you end up with what you are using in your working code. i think i would learn SO MUCH from that.

Well, I'm inspired! This is so impressive, I love it. A while ago I made a little casual mobile game, and after I finished it, I had this idea to do a few de-makes of it for older consoles. There's something really charming and fascinating about the challenges associated with making something for older hardware. I never got around to starting that project, but you've rekindled my interest :)

Been following you since I discovered my passion for embedded programming in the Summer of 2020. I remember when this project was just a hacky raycast tutorial for the GBA that I played with when I was learning the basics of embedded C on the Game Boy Advance. I've become an established firmware engineer since then. Just accepted a Senior Role at a big company. It brings me a lot of joy to see what became of your channel and the project. You are genuinely insanely talented to have achieved this on such limited hardware, and one of my inspirations in my career. Here's to 100k subs 🥂

I am blown away at how cool this is friend. The technical challenges I see you solved on your own are absolutely incredible. Floor ceiling height, portal solving, translation not only in editor but in engine. The texture warping based on angle of view I wonder if that is like a simplified version of mip mapping? Very very very cool. Better than any 3d engine I've seen on GBA. I was an enthusiast as a kid always looking for advanced 3d engines on the platform, best one I ever found was ecks vs sever. Yours is obviously superior. Incredible work.

the gba and n64 have been getting a ton of progress to squeezing the most out of their hardware recently

This is really cool. Are you planning to add support for FPSs or dungeon crawlers?

I love the music you’ve chosen for this video, big fan of the Linn drum and FM horns

so for now this is just like a level editor? will there be events triggers, particles (FX)? editing the view distance to have a fog? adding 2D elements to make items (like DOOM)?

This is amazing. the retro ID engine style, it's look and behavior, is super nostalgic 🤩

this makes me so happy, looks like a really fun engine to use. ill def be trying it out sometime. i cant wait to emulate it on my 3ds

You've gained a sub! The fact that this is even possible on the GBA, no less by somebody in their spare time, is astounding!

This is so cool, you're an absolute bada$$ for making this and giving it out to the public.

Going to try to think of a game I can make with this, this would definitely be a usable tool for me. I had game design ambitions for a while but my ideas required more talent than I have. It will be tough to pare down my thinking to this engine but the fact that it's achievable is very motivating. Thank you for this.

Wowsome! Really amazed! I do know how painful hard coding these things can be, and I'm very happy for you! God bless you!

Wow! This is like the LSDJ of level editing. Really looking forward to the release

I find it inspiring how this reminds me of Tomb Raider Level Editor from 2000 so much

this is absolutely insane

I legit can't wait to mess around with this. I already love using Doom Builder, and this seems just as fun, if not even more interesting because of the platform.

This is SO cool, gonna try it on my flashcart soon! If it does get to a stage where an actual publishing is possible, it would be really neat if levels could be shared via link cable somehow. Not that it would be the most practical method of doing so, but it would be fun. Keep up the great work regardless!

First things first I am now subscribed! 1:50 I understand what you mean, but I do really hope you revisit handling the other systems within the game itself! I LOVE the idea of having this all-in-one game that can handle basic graphics, code, and level creation B) Anyway I'm excited for what you're making and I'll play around with it regardless!

I can't wait! this looks really great and I've been waiting for sure! Goodluck and take your time! amazing work!

Wow, this is awesome. Cant wait to try it out. Very impressive!

You understand this, you actually know what ticks in game design. This reminds me very much of 90's and Jazz Jackrabbit 2 and why it became such a massive phenomenon. I call that triple S: Simple game, Simple rules, Simple editor.... but the inner workings of jj2 were what made it shine. Aside from having some of the most fluid character controls, game's map editor was so extremely simple to grasp and so intuitive, a kid could use it and create something cool. Yet, at the same time the "events" allowed you to create really complex mechanics and create stuff that wasn't originally even meant to be done with the game. Things like new game modes, mechanics and so on. Fantastic multiplayer support was the glue that bound it all together, creating one awesome package. I highly recommend you to check it out and take a a few minutes to check the game's history, there's a lot of neat things to learn from it. That and both the game and it's community are still alive and kicking.

This is amazing. I’ve been undertaking my own niche projects and this inspired me to keep on trucking. I can’t wait to get my hands on this! Thank you so much for sharing your work with the world. You’ll have that physical in no time!

Insanely impressive. Can't wait to see what people will make and attempt to port

Hell yeah. Can't wait to try it out.

I would've loved this as a kid! I can see myself spending hours just making levels just for fun, it's very similar to something like DoomBuilder, I will definitely be giving this a try especially when it's more complete. I've even got a couple of rewritable cartridges I can use for the authentic experience!

It reminds me of the time when I was learning how to use Ken Silverman's BUILD Engine. Same approach. With sectors, height, shading etc.

this is just like Duke Nukem, Blood, Shadow Warrior, etc. it's pretty cool to me that this tech works on a gba

So cool! I had a lot of fun several years ago learning GBA programming and making my own stuff from scratch... definitely a fun system to build stuff for!

Man, that is so impressive. You really boosted my motivation in programming. Love everything about the project, how intuitive the controls and how performant this neat 3d sandbox is :)

This is an amazing achievement. Not just that you can get such visuals. Not just that there's an editor as well. But how it all seems to work fairly seamlessly, fluidly and with a nice interface despite the limitations. I cannot imagine the work that went into it!

This is the best!! If you can get trigger lines to make sectors move up and down, activated by walking over or interacting with/pressing, that would give it so much flexibility, people could build games just with that, easily. And with items for player to pick up the whole thing can open. You can have quest items, keys to unlock trigger lines, text boxes, the list is endless, and that's still with no enemies. I'm very excited to see where this project goes from here. One thing - it's interesting to have brightness applied on the individual walls, instead of entire sectors. That may be unnecessarily fiddly. Looking forward to make something with it

It's honestly quite a miracle that your editor's user experience is quite intuitive on a GBA, of all things. I recommend using icons for the buttons for better readability.

This has a lot of advanced features for an engine targeting the GBA. Nice! Super impressive!

This is simply amazing. Will this be further editable so as to insert npcs/enemies/tools to use? Or is the system memory already at its limits?

I can't believe I missed this! Dude I bow to your dedication and I have to say I'm so happy that you have something rewarding (to yourself, most importantly) after unimaginable dedication and frustration and no doubt there were points where you considered giving up? What an inspiration. Best thing I've seen all week on RU-vid and it's been a loooooong week!

I know its a looooooong shot, but some kind of simple visual scripting logic so that we can make 3d pacman / dungeon crawlers adventure games ?

Pretty cool! I will definitively try this out. This is quite impressive, i bet MVG would like this.

i love the idea of it being multiplayer! cant wait to see how this evolves. great job so far.

I've been wanting to fill up my time being homeless doing game dev for a while now, this seems perfect! I cannot wait to get my hands on this !

Subscribed! This is awesome - keep up the good work. If your looking for ideas i would say adding modes to the editor would be great, build your level, select a melee or gun mode and connect via gba or emulator with friends, or bots. simple modes but if you also optimized the controls for each, sword fighting/maybe a block function and gunplay and maybe added items to buff the simple health stat and maybe a bonus stat you could get a good gaming experience imo.

That is bloody AWESOME! Crazy that your creating 3D in a system that wasn't supposed to use 3D to begin with. This is SUPER cool! Best of luck and I hope you achieve your dreams!

Dude, I love it, I sure will check it out soon, I don't have an actual gba anymore but my a DS sure will do it too as it has perfect compatibility to the GBA I quite like how you go through everything and show how it works, creating a nice simple demo map. That all in the limitations of a console that is over 20 years old and even at its release date not the current standard. One thing I would really love is having something like simple background music playing (maybe even per-sector music you can set), it doesnt have to be complex but something simple because in my opinion music is a nice thing to add (If wanted I could even help composing something that would get into there, of course only if you want to add that) Another thing I'd like to see is having save-slots, from what ive seen you can load and save, what if you have multiple maps you want to have, especially on a real gameboy multiple maps might become a real challenge to handle if you dont have a way to backup and restore save files. (if you already can save multiple maps easily, I missed it and I am sorry) If you end up releasing this for an actual GBA, I'd love buying it, it has some work left but you already created something unique that many people will enjoy! I am not a developer but I understand what kind of hard work and dedication it needs to create something like this but it definitely is something you can be proud of!

This is one of the most impressive things I've ever seen. This is a cooler tool than what most pro-level game engines have built into them. You just...made this cause could. Freaking amazing. Bravo, dude.

Please, don't give up! This project is absolutely amazing and inspiring! 🤩

You make the process of making and editing maps look so simple, easy, and clean. Great job!

So in terms of game objects, I really would encourage you to make ways for us to apply our own simple behaviors to objects, the excitment starts with map making but the thrill is knowing you can make ynique weapons collectible objects and unique enemies. First of all the number 1 need here is the ability to draw custom pixel images and apply them to objects. Either way this is great I love it and my eyes will stay honed in on this glorious project

This is awesome. I'm hoping this evolves to be the GBA version of GBStudio because being able to play my GBA creations on my Analogue Pocket would be amazing. Great work!

MegaMan Legends... Advance

This is pretty awesome! I watched your early DOOM software rendering stuff a few years ago, when I was researching that sort of thing. You've really gone the extra mile with this editor, nice work. That's pretty much every feature I'd like in this sort of game. The only thing I'd add is more shortcuts, which is obviously more fitting for PC. If you start running out of room for shortcuts, maybe you could have Start enter a second input mode. Like after pressing it, it interprets the next input from a totally separate set of keybinds. So on top of the regular keybinds and menu controls, you could press Start and then L to toggle 2D/3D, Start and then R snap the grid view to the player spawn point, etc.

This looks very similar to the Doom Engine (no rooms above rooms, no angled walls, sector lights etc.). Very impressive.

my little girl just dreaming for minecraft on her retro handheld, this is awesome!! thank you.

You are flat-out THE BEST GameBoy Advance developer in the world. Like, really.

Imagine if this was actually released back on the GBA in it's heyday; if it included pre-made weapons, enemies, etc. you could also place around the map, then share your levels with others via a link cable (the level would be saved to their cartridge so they could replay it later.) This could've been a huge hitter on the system, and maybe introduce a lot of kids to the world of game development. I can already imagine the alternate timeline where people reminisce about going around summer camp sharing levels with each other, or the threads from people digging their old copy out of storage and playing a level they got from a kid 20 years ago, wondering where that kid is nowadays.

This goes crazy but i hear the severe lack of undo button. Im very sorry for reminding you and i pray the potential process of its creation is as streamlined and seamless as possible. Good luck

being able to edit the sectors in real time is brilliant, can't wait to fiddle around with this haha

i smell the elder scrolls gba

This is some impressive stuff!! If you add actors/objects and maybe an in-engine texture editor, it'll be a complete package!

I can’t wait till this is out! Perhaps a way to make textures in game with a simple paint tool

I wish the PSP received this love and dedication, the GBA is a great console, but the PSP is definitely one of my favorite portable consoles.

I am super impressed just by the fact that you set your goal and stuck to it, you must be very passionate. If it's not written in c, what language is after all? Now I am wondering how/where to get an GBA flash cart, I still have an original GBA and a micro :)

Looks amazing so far!

Amazing job, can't wait to try it! My only two cents: I believe textures and the levels overall would look better with a more pixel art style, rather than realistic/noisy. Other than that, this looks fantastic!

You’re doing a good job, and I expect your software will stay relevant for many years.

Very interesting! This is very similar to DOOM Builder.

i love that youtube thought it was minecraft :D truly amazing work the amount of brainpower that went into this is crazy ♥

this would be amazing for vr game engine creation for beginners cool

You're a legend. I'ma download this as soon as I have time to try it out!

My type of autism : Niche Projects like this

Babe wake up new progress on the 3d gba engine dropped (really though incredible to see how fast youre progressing on this)

Hope someone will make an awesome game and actually sell cartridges 😊

i think it'd be awesome to see a story based game out of this

It would be cool if you created a door element that accesses different sessions, perhaps a key item that allows you to enter some doors

I love building maps just for the heck of it, and this looks really fun. I'm wondering if having some kind of window texture would be a decent idea, but that's probably me thinking of my own ideas. Still, I'd probably just be spending hours, if not days just building new levels.
