Game Disassemblies
Post Posted: Sat Oct 06, 2007 11:39 pm
I don't suppose any user-commented disassemblies of commercial code are available anywhere on this site? Seeing Maxim's example with the Color/Switch test got me thinking, and I know Bock mentioned in another thread that he had partially gone over Phantasy Star (which I'm particularly interested in). I know my self-education would definitely benefit from such a resource.

I have Columns source code among other things.
The thing is, to learn the basis I think you don't want to be reading source code of this era. People were pretty much isolated, code optimized but often very personal, barely commented, messy.

Maxim did a partial (complete?) disassembly of Phantasy Star. This kind of thing may end being better than the actual original source code of the game (which was probably lost).

You can learn better from modern documentation and active developpers (this site, but also probably other Z80-machine scene that are more active, probably MSX scene, but I haven't checked it).

Yes, that's what I meant, comments on user disassembly. If you get around to it, Maxim, I'd like to see any you've made on P-Star, since I've been examining that one myself.

Thanks for the tip, Bock, I'll give the MSX boards a shot too.

http://svn.smspower.org

I didn't do anything on it in years, but it's not too hard to pick it up.

I was looking for a documented disassembly (done by hand) of an official SMS game (doesn't have to be a specific one). Your Phantasy Star disassembly seems to be offline since quite a long time now, is there any chance to obtain your commented disassembly?

I'm currently working on a SMS emulator (just for fun and learning purposes), I found some documented BIOS-disassemblies which helped me a lot (for learning and debugging).

Is there some other disassembly-project online I could consider?

Thanks + bye!

https://github.com/maxim-zhao/psrp/tree/master/psrp/Phantasy%20Star%20disassembl... - still quite abandoned
https://github.com/maxim-zhao/micromachineseditor/tree/master/Analysis - quite close to complete
https://github.com/sonicretro/s2smsdisasm
https://github.com/Kroc/Sonic1-Z80-ASM

Not games but at least complete - and maybe what you already found:
