The Sonic Decompilations Megathread.

[Ian Micheal]

Yeah it is with chui 1.2.13 and some know how we can far out pace the SDL in standard kos.. so please dont port it using the junk included in kos with the memory leaks and slow video..

Which ever i will fix it when it's done or when some one releases the sdl1.2 port

Sappharad posted the source code to his sonic CD dreamcast port in September if anyone wants to compile it.

https://github.com/Sappharad/rvm_soniccd/tree/dreamcast

He told me on youtube today that he is not focusing on it right now.

[Anthony817]

Nah dude, check the date lol. That was from September 2019...

[dcsteve]

September was Sappharad's words not mine. Check the comments from 10 hours ago on the youtube video link. You posted in that thread months ago. Anyway, that code from September 2019 is the same build from the video.

I will see if it builds it's using old opengl we have much better now with GLDC..

[dcsteve]

Nice Ian. Hope it works!

I'd really like a sonic adventure 2 battle port. I know it has sonic adventure 2 but to have chao karate would be a dream come true.

almost built

[Anthony817]

So with GLDC could this theoretically fix most graphical glitches? It was already running full speed in the video from 2017. Would sound be working in your version Ian?

Pretty sure it be fine all sound is disabled just due to the sdl part of the sound being null out .. there some wierd hacking of opengl and it seems pal worked but used to much texture space vram so he disabled it due to that..

Anyways i have no idea what files this run but i got it built to an elf

rvmscd.rar

(759.89 KiB) Downloaded 259 times

Have no idea if it work at all but i got it to build with some small changes.. I dont have the data files to test.. Might have to change all the data paths to read from the cd yet any one can pm me the working data files i can test it but if not here is the first build

here is also the build-able src for dreamsdk and kos 2.0 type make clean and build .. i cant understand some of the hacking of opengl kos commands in this why this was done.. or nulled out sdl sound maybe for speed.. ? or maybe it's sdl2 sdl sound but it looks very easy to port that part to work.. with some simple mods to pvrbuffers.c he could got 1.5mb more texture space vram
