04-Tempest Video Game Hacking - Adding to the Classic Game 

Need more of this series!! I would like to see how this plays out.

Love this series, i’m a hardware and software guy and regularly still fix old arcade hardware. Can’t wait for part 5.

I hope you are going to have more video's on this topic. They are quite interesting even though I am no programmer..

Tempest decoded part 5 coming? Dying to review code to see if things like fuseball aggressiveness, flipper initial movement direction etc are random or triggered by certain conditions etc...

Came by to endearingly say where is part 5?? Only because I love your videos and I was so excited to see the next part (= Any video format you do is great

Came for Fat32 Format, staying for Tempest hacking. Looking forward to Part 5.

Hi Dave - you rock! I hope you get to finish Ep5. Keep well

Dave, this is one of the greatest things I've seen on yt in ages. Please, continue with the story :) -fbneo dev

Hey young man thanks so much for the effort here! I really enjoyed it! I attempted a similar disassembly project on a old Asteroids cocktail unit I owned. I was a game developer back in the mid 80's and this brings back such good memories. I can't believe how much of 6502 is still in my brain after 35+ years. I still remembered the op codes. You'll get this joke. I was on my companies softball team and our jersey numbers were in hex. My Jersey number was EA. (Tell's you what they thought of my sports ability.) Anyway thanks so much again. I've been smiling all morning. - Chris

Believe it or not, it was a pipe dream of mine to learn about the inner workings of Tempest code on this level, being an avid Tempest player, and a programmer who's spent years writing assembly (mostly for specialized DSPs). I have nowhere near the breadth of system-level knowledge required to tackle this reverse engineering feat, as became clear from watching these videos, so I am grateful to you for undertaking and documenting this labor of love. Thanks for allowing me to vicariously live out one of my pipe dreams through these videos. They are fantastic! I echo the earlier comments hoping for more installments.

Aww man, I need the next part. Super interesting stuff!

I hope there will be more to this series. Tempest is my all time favorite arcade game. Loved the crisp clean lines of the vector graphics display!

@Dave's Garage I wanted to thank you for taking the time on making these series :) I enjoy them all, also learn great deal! Although game play wasn't shown. I have taken it like cliff hanger movie, where need to wait until next series. I am pearl, python guy. So in the meantime I have the information you have provided in how to do it and attempted to make my own. I call it Empowered by Dave Plummer = EBDP for short. Where roms seem to work, however more work is needed on my end. This is fun stuff!, but it is time consuming. I am not retired so it take me longer to get it done right.

Im anxiously awaiting Part 5. How will I ever sleep? I need to know....lol

Where"s the rest of the tempest rom hack story? You've got me hooked now. I have to know. LoL.

Very cool series. Any chance of adding more episodes? I was all ready for the bug reveals, and .. no episode 5 :(

Hi this is not relevant, but I just had to stop by and see the guy that had such a big hand in building the systems like task manager and other windows things all those years ago that we now take for granted. Massive respect to you!

I just can’t stop watching these videos :) Keep up the good work Dave!

Thank you for this short series! Would love to see more on the 3 weeks of reverse engineering the assembly code.

Hope to see more, love these kinds of videos. Thank you for doing them.

Still looking forward to Tempest hacking part 5! Really enjoy the way you explore how the game works under the hood.

Dave, the suspense is killing me

Would love to see more! Thanks Dave!!

please do more of these. these are awesome!

@Dave's Garage I taught myself 6502 Assembly language on a Commodore C16 back in the day. I used to load up games and reboot into the assembler and trawl through the code where the game was and change stuff to see what happened. I would always give myself 255 lives too, lol. I miss the old C16.

I look forward to the followup on this, keep it coming :)

Hey looking forward to the next episode to the series.

I would really like to see more of it! It makes me miss old times of tinkering with SE phones firmware and iphone software..

Don't leave us hanging... Really interesting series sitting on a cliffhanger finale.. Poke 16384, 256.

Is there going to be a part 5 soon (or ever)?

Are you going to be doing any more of the videos in this series? I absolutely love Tempest. Thank you.

Dave, is there any chance of revisiting this series to finish it out? This is the series that got me to subscribe, and while I love all of the videos, it's sorta sad that the thing that hooked me is still unfinished. I realize that a couple years passed, so your interests have probably changed, or you no longer have the footage or whatever, but even if you did a retrospective and glossed over the final bits of your original vision, it would give us some closure. 😂

Oh no. I binged the first four. Where's #5? I really want to see this in action. I did the thing with the subscribe and the thing with the thumb icon, but it's still not showing. Perhaps I just need to do the share with my friends thing. 😜. No pressure, Dave. 😎

Hoping to see more of this!!

Your Tempest disassembly series is awesome, although some people might not click - the principles are similar for all reverse engineering exercises - whether they like Tempest or not - for me, Tempest is one of my top 10 arcade games of all time.

Superb. Thoroughly enjoyed this. Is there any chance of the disassembly being released?

Hope to see the next episode sometime

Such a cliffhanger! Anxiously awaiting Part 5.

@Dave's Garage, any chance you can continue? I just found your channel and I also love tempest!

I remember playing this game in the students’ union bar at college. (early 80's ) Used to love it with its vector graphics display it just shouted out the fact it was not the norm. Then it was changed out for another game and I’ve never saw the game again. Would love to be able to play it again, but with the death of crt’s where would you find a vector display.

I'd love to see how you could programmed/added data for *new levels* and what they look like in Part 5. While I can see how you edited the table where you can start I"m curious how you define the actual look of a new level.

Just found these cool videos. I can't say that I know much of anything about programming, but I still find it all most interested. But I am also a long-time player of the game (also since it first came out and also completely fascinated me). Also consider myself to be quite a good player and can get to the green levels and beyond. Of course I own my own machine and have since the early 1990s :) . From a fellow expert player to another: Is there any way you could see your way to releasing the hacked ROMs with the Purple levels for folks like myself to upgrade our game with? I would LOVE to be able to try out these new levels!!

Dave, do you plan on adding to this series? This is fascinating stuff.

Cannot wait to see more. 👍

Did part 5 come out and i just can't find it? Be great to know how this ends. Nonetheless great viewing so far, thank you.

Great work... 👏👏👏

If not an episode 5, could you film a short bit of it running with the changes to the level selector and colors?

Adding another voice to the crowd looking forward to part 5

This Tempest series is very cool! Will you ever do the same thing for Atari Space Duel? There are some things in space duel programing that I would love to figure out.

Thrilling conclusion please! :)

Cool video! I was wondering your thoughts on the new MS terminal, and if you were going to do any python code videos? Either way keep those fresh vids coming!!!!

Hey Dave Awesome videos! Are you planning to share this work, ie could I get a copy of your source/make files so I can also play with the code to?

Episode 5 sounded like it was going to be super interesting, especially the stuff about the copy protection. I'm very sad (and a little annoyed) that it ends before you got to any of that. It was very cool, nonetheless.

Saw the first video... couldn't stop seeing the rest... (as the people here... I just come to see the "Task-Manager" video... then I stood ;-) One thing you mention regularly is NMI, It is useful to say that this is the "Non Maskable Interrupt" vector and maybe a bit of explanation as it works in 6502 (much as in Z80 i think) would be useful---

Where's the next part?

Hey man - you left us hanging! Where's the rest?

Just binged this and find this cliffhanger ???

V impressive, thanks :)

Lets see part 5!

Hey dave. I was curious if you finished this project (the extra levels). If not, it would be pretty rad to see why! If so, let us see it!! Thank you again for the comment. I am a like and a subscribe for you dave! :P

Is / when is part 05 coming?

please make episodes 5 through 77 thanks

Oh noes! Now I wait for season 2. This has inspired me to try and reverse engineer the C64 Kernal some weekend. I’m hoping someone’s already done the decompile and symbol renaming.

Are there any more videos in this series coming?

Is part 5 out yet?

Love to see the end of my this!

Will there be a #5?

Ahhh… y además aparte del comentario que hice anteriormente para saltar las arañitas de colores sin que hagan daño es muy fácil, al menos es lo que hacía a menudo durante el juego… Saludos a todos…😃⚡️

"Fire fruecken wenn richtig", yep, can relate...

will there be a #5?

Where's part 5‽ And what do I have to do for a copy of that disassembly? I'm not above begging.

yo Dave, where is episode 5?

What Michael Hoskins said. Was watching each one and it ends at this episode.

Is your source code available, I haven't heard you mention a link?

Need a number 5

@1:13 I did EXACTLY THE SAME THING! hahaha also what's up with the LASER TEMPTEST project Dave?

I'm envisioning that the delay for installment 5 is that he's busy porting taskmanager to the tempest hardware, and you'll no longer kill the spikes by shooting them, but rather you'll have to select them in the task list and kill them that way.. :-) Seriously though.. where's #5, and also are you planning to share the code? It would be fun to play with in MAME..

Waiting for 5

Ugh, I hate it when they cancel a series after a cliffhanger 😂

Hey Dave! Are you related to the other Plummer the actor?

where is part 5??? O:

Please finish this!

Ekk! Just realized there's no part 5. No, nooooooooooooooooooo!!

Suggestion: write a custom application for the multimorphic platform.

Episode 5!

Where is the rest of this????

I assume Atari stepped in with threats of copyright infringement litigation, hence, no part 5...?

What ever happened to 05-Tempest Video Game Hacking?

No... It can't end...

You can't stop now...........

5:09 line 199 has spelling error in the comments Dave.

I guess the Tempest series got unplugged.

Sad face emoji, Where's part 5? I know it's a bunch of work to make these and the view counts a low. But if they are in the can, let out Prince Albert.

I know im randomly askink are rlly the dude who made the taskmng

Are you really task manager guy cuz Thiojoe brought me here and you dont mention anything bout it.
