Re: Has anyone tried to make a website specifically for revers engineered games?

I'd like to learn efficient techniques (if any) for disassembling NES-stuff. Running the code through a disassembler can anyone do but understanding and documenting it later, well, it's a different story. I have a theory of working "backwards" here. Running the game and then analyze each memorylocat...

Re: Has anyone tried to make a website specifically for revers engineered games?

Now for something a little off the off topic. This post got me thinking about sharing how I do it. I just started Mike Tyson's Punchout. I'm still getting the disassembly to a point where I can work on it. I haven't really started any of the reverse engineering. Would it be interesting to people if...

Re: Has anyone tried to make a website specifically for revers engineered games?

I meant more like, how did you disassemble the entire game and figure out everything?

I just finished a complete disassembly of Dragon Warrior 1 (https://github.com/nmikstas/dragon-warrior-disassembly).
Perhaps slightly off-topic but how did your workflow look like when you did this?

Re: Nintendo "Gigaleak"

I'd rather have seen some NES sourcecode, that'd been nice. :)

The closest NES source-stuff in these archives I guess are Super Mario AllStars.

Re: Nintendo "Gigaleak"

The ROMs doesn't seemed to be saved in .NES format (not very surprising..) or come with proper filenames so I guess it'll require some detective-work to figure out what's what. EDIT: Files seems to be split in PRG and CHR's. Filenames seems to be related to developer and game-name (initials). Obviou...

Re: Nintendo "Gigaleak"

Sorry if I spoked ya'. :) Many people are probably not very happy about this kind of stuff. Myself I find it fascinating what people can dig up through these old sources. There are plenty of articles about what people have found..

Re: My first attempt at NES graphics

Slightly reminds me of one of my favourite NES games, "The Goonies II". :)
I think it looks promising. I however might not be a big fan of the brown areas (the walls/ground).
Keep it up. :)

Re: FamiStudio NES music editor

I just used it for testing, I think the NSF import is really cool, I didn't bother about possible sideffects. :) And yes that song is awesome. :) So I am back at square 0 again, FamiTone2 obviously doesn't support all features so there's no point in using that for my possible future NES-stuff. :( ED...

Re: FamiStudio NES music editor

I attach an NSF from "RcProAm", the titletrack sounds slightly strange in the beginning atleast when saved as FamiTone2 and playback using that code..
This is how it should sound:

Re: FamiStudio NES music editor

I suspect there might be something off with the FamiTone2 export-functionality? I've been in contact with the FamiTone2-guy and there doesn't seem to be any obvious problems with my code.

Re: FamiStudio NES music editor

Got it running, NMI was causing problems. But the music doesn't sound as it sounds in FamiStudio (or exported as a NES-ROM) so there's still something wrong. I attach a new example if anyone's interested.

Re: FamiStudio NES music editor

I found some FamiTone2 example I experimented with but I can't get it to play anything. I got the example code from https://shiru.untergrund.net/code.shtml and I stripped the example from just about everything but the music-code but I'm probably doing something wrong. I'm using ASM6. Anyone see anyt...

Re: FamiStudio NES music editor

I'm interested in a replayer that's easy to implement and use. :) As a former demo-coder (sort of anyway) on the Commodore Amiga platform and I'd like to try to code some stuff on the NES aswell. On the Amiga we just included a replayer and play our music but on the NES, well, things are a little bi...
