Sonic 3D’s LEVEL CRAFTING mode. This “changes” everything 

[Makes a video about level editors] [Casually confirms one of the oldest unsolved mysteries in the Sonic scene using a single crab]

Fan communities do so much work to theorize and recreate things from beta screenshots. Meanwhile this guy's all "I saw this enemy in a screenshot so I dug around in an old build and here it is!"

"Building levels from scratch on computer and uploading them to cartridge is so time-consuming... Oh, let's build levels ON Sega Genesis!"

Holy crap, I want! A bit like debug mode from the classic games before this. I'm curiously wondering if the prototypes we have already contain this feature...?

god to me: i'll give you a friend don't worry god later: oops, memory clash

wow a beta rediscovery... even though its just a beta crab thats really neat to see.

4:39 *- Knuckles convertion has started -* *- 50% completition -* *- Operation aborted -*

I think it’s super cool and interesting to see development tricks like this.

That crab is pretty cool

Good luck putting rings down while you can pick them up as the cursor. :P

Sega should totally create a Sonic level creator game, like Nintendo did with Super Mario Maker. I know the original games on the Genesis have a debug mode that allows you to place objects, but I'm talking about a game that lets you create new and original levels.

If Knuckles and Tails are having trouble standing together, how do they do it in Spring Stadium?

So basically..... Sonic 3D Blast Maker? Also that crab reminds me of the Shellcracker enemy from Metropolis Zone.

"**places Tails** Hm, he looks familiar!" XD

More mind blowing stuff, dude. I always wanted to know how to make a 2D isometric game with all the complexities of different slopes like in Sonic 3D Blast, but its hard to wrap my head around. I really hope we get to play with this thing if possible.

Yay voiceover

Loving every video on the channel! Also, what a pun in the title hahah

Oh man, I'm so glad about your channel! Seeing all this in-depth information about such amazing games, I dunno how to put it in words. It gives me such a warm feeling. I love your videos and hope to see alot more from your work! =)

I really enjoy seeing your insider perspective on a lot of the games I grew up with. I enjoy your content either way but voiceover is actually highly appreciated here, great vid!

You are doing god's work friend. I beat this game 5 times throughout my days, anyone who said it was meh wasn't fast enough.

Sega! Watch this and release a Sonic 3D Blast Maker! Then you can work on sonic spinball maker, dr. Robotnik's mean bean machine maker and put them together in a mega pack. If it goes well, then head onto the sonic main series; so we have a sonic maker and a sonic spin off maker.

I love all of these videos, but you don't need these clickbait titles. This stuff is already interesting enough on its own! :)

Thank you for all the content concerning the Sonic games you worked on ^^

OMG!! That was amazing. And more importantly, "official" enemies names. Hunter, Scouter... That's something was missing at the manuals. Can you list the official names of the game's enemies? By the way, I would love to see editor of the Satutn version in action, once it don't have the same limitations of the Genesis/MD version... It even have a cute mole in Green Groove Zone's walls.

So cool to see 3D Blast's level editor. Thanks for sharing.

Very cool to see, especially that crab. Love these videos!

Sonic 3D Level Blaster

Dude, you did amazing stuff back in the day

Oh man, the Sonic ROM Hacking community is going to be in an uproar about not having access to this. Anywho, great video man. Sonic 3D blast was a pretty big part of my childhood , so it's nice to see how it was developed. Hope to see some more groundbreaking Megadrive demos uploaded in the future.

Really love these videos. It's fascinating to see one of the game's actual developers talking us through things :)

Wow this was very insightful. I've been thinking about using SFML to make a game, but I had to hard code the level and I didn't know a simple was to implement a level editor. This gave me some ideas

Amazing stuff. Thanks for sharing. Sonic 3D has always been a very high quality game, and this is one of those indicators to why! What a programmer! Great insperation for us that grew up with this :D

This is fascinating stuff. Awesome seeing how this game I played as a kid was constructed.

This video was really interesting, I'd love to see hacks of this game. Super excited to check out the rest of your channel!

looks very interesting, I can see why it would of been time consuming moving all those items, objects and enemy's to another spot.

These videos are awesome so glad I've found your channel

I love seeing how games are made its so interesting plus because I'm going to do a course in game design next year

WOAH!! this amazing! Every video you release contains millions of dollars' worth in game dev info

Keep up the great work, these videos are awesome

I really appreciate you showing us all this cool stuff, it is very interesting! I wish more developers of classic games would do that.

That's interesting to know how Sonic 3D Blast was made; great video mate

Impressive stuff. And you dug up a beta element that we have only seen from screenshots and put it in the game? Props to you!

Incredible! You should look into more sonic games and keep digging for goodies

I wish more developers of classic games would come forward with an "inside look" of their stuff. It's pretty much what a lot of fans love to explore and want to see! Like, if some Japanese developer for Zelda: Ocarina of Time was like, "Hey, here's my RU-vid channel showing you early works of Zelda" people would go nuts. Keep it up!

this is quickly becoming one of my favorite channels on youtube!!

The crab!!!! And wow other unused badniks!? What a treat ! Thx man !

That is really cool! You might inspire me to try game maker again xD

It seems like every day Gamehut finds something new and exciting. I love this channel. Thank you for surprising us almost every day.

Holy crap, this is so amazing!

Kudos to all the people commenting with actual questions about the tech! This game was a new concept made after sonic team was bored with the hedgehog, and was bound to meet a hostile audience from the get go. It's amazing to get insight into a game that was released so long ago, from an original Dev none the less.

Looks so cool!

I love these informative videos on how games are made. Perhaps you could do a video on how to do 3d polygons used in sonic R

Kinda crazy how good some of the 3D rendered models and animation look in this game.

WOW! Unused stuff too? That's cool! :D

Your videos are very interesting for me. You have no clue how big a part of my life this game was for me on Christmas 1996. I swear I was the only guy in the world who got used to the isometric Gameplay and physics. I didn't care, it was a new sonic game! I always thought whoever made this was a programming genius! so uh... thanks for the childhood you programming genius!

When you mention how an object differentiates its colors in each zone, I think that also works in a similar to how background sprites are loaded particularly in the 2nd portion of Sonic 3 & Knuckles

Great content. I'm very glad youtubes algorithm made a decent suggestion for once. Too bad not all your videos have voiceover. Kept me from binging all of it.

It's so amazing seeing how TT has put these games together! Were you around for the Lego games that TT is now known for?

A lot of games did this sort of thing. Some left the code in the final version. One SNES sports game contains an elaborate windowed, mouse-enabled tool reminiscent of Windows 3.1. Ocarina of Time's leaked debug build has an editor for camera paths, using the memory card to save. Pretty neat stuff.

That's awesome!!! :D

Maybe we'll find a proto that still has the crab behaving as it should

I’ve only just discovered these videos, and the Coding Secrets ones. I’m addicted!! Please make more!!!

Just passing by to tell you _thank you_ to you and Travellers Tales for creating one of the _most immersive worlds of my youth._ Sonic 3D Blast always marvelled me. I guess I had a hard time wrapping my head around the fact that Sonic had a 3D game. Every level seemed so large and so vivid!! Every turn revealed something I had never seen before... Passageways, tunnels, crackable objects that led you to a small lost corner of an amazingly huge world... And combined with the Flicky mechanic and the out-of-this-world OST by Jun, conquering every stage actually _felt_ like _making a small step towards a massive, meaningful end_. Thank you for all those memories, Jon! And what are your favorite levels and music tracks on the game?

I had no idea that there were so many limitations back then! I would have just said "Screw it. I can't get it to work" because I wouldn't have understood why things had wrong colors or corrupt graphics. This gives me insight into how much patience, knowledge and skill early programmers had.

Releasing this level editor will sure make happy tons of fans and we may be able to actually see more romhacks of this game

This Stuff Is Really Cool

The crab seems to be based on Sonic 2's Shellcracker, which I don't remember there being very many of in Metropolis Zone where it appeared. It was a stationary machine that had an extendable claw to use for melee attacks. Based on what we saw here, my guess would be a simple side-to-side patrol similar to what you have here, placing the crab robot in what could be considered defensive positions from Robotnik's perspective; pathway openings, near the giant rings, and so on. Another possibility is the crab being a hybrid of the Shellcracker and Sonic 1's Crabmeat enemy, which had a short-range projectile; but given that you didn't find any projectile data for it, I'm, thinking it was more defensive patrol behavior.

Nice Intro ! :p

this man really out here making a 3d level creator on a genisis

I loved this game so much as a kid!

I think the crab enemy may have been used in either Green Grove (where there's no "back-and-forth" enemy type as well as an extra spot for a flicky, the green one, specifically) or in Volcano Valley (since the level already has 2 of the aforementioned enemy types, and it seems to have an appropriate color palette).

I never knew that secret Sonic 3D Blast data would be a part of youtube that interests me.

This video completes my childhood.

It's all there jus takes time and patience to make own levels sooo cool

Very interesting! What about the tools used to design and layout the map itself?

Loved this game as a kid, it's fascinating as an adult to see what went into it's creation. Wish they would re-release this on the Virtual Console.

Seems pretty robust and relatively easy to use (at least in terms of your team getting stuff done).

a game is always made 10 times more fun with a level editor. it's the sole reason i still play doom to this day. granted in this case things get a bit complicated due to hardware limitations, but heck, a buggy debug mode is better than nothing

Nobody: Sonic 3D level editor: KNUKLES

TCRF is going nuts, RELEASE THESE ON THE INTERNET!

Damn this is some crafty stuff! Is there any reason the position to the newly selected entity is panned to the new one? I mean are there any constraints or is it done on purpose? Great content!

Damn you worked on a lot of classics

This is really cool, can you guys do some videos about the saturn version too since most of us havent played it. ^^

This is amazing! :) I have a question, Is there a way to change the level design?

Never thought I would know this

you're making me appreciatte sonic 3d blast A LOT more. ppl always talked shit about this game I always thought it was great. ever see the super sonic hack rom of this game?

This is a million levels of fascinating to me. Thanks, as always, for sharing! Did you have to write a new object and do some manual mapping work to show the crab to us, or was much of that already laid out more or less before re-adding it?

amazing

Jon how did you create the prerenderized sprites for this game? Can you make a video talking of the proces?

Wow, didn't realize how the RAM was dynamically allocated to on-screen objects like that. (Through a corruption video or something, background tiles appear to have a similar system. One of your prototype videos, the one with the splitscreen, does it too.)

Do you have any interesting material on the Saturn/ PC Port? The PC Version was my first sonic game.

5:38 OH YEAH MR KRABS!!

clever pun in the title

Sonic 3D was the first Sonic game I ever played, and it was at a Target Kiosk.

What was your involvement with the Saturn version of Sonic 3D Blast?

This is a really interesting approach to level design considering when it was made. Aside from that i'm interested in what was used to make the actual stages themselves. Was it a proprietary tool or something more conventional?

Wow cool! It would be awesome if this was developed further and made into a sort of “ sonic 3D maker” like supermario maker on wiiu!

This makes me wish I was a real coder. I just hack Python until I get the output I want. What you do is real problem solving. Love it.

God I wish we get this someday.
