Re: Getting around the DPCM bug in a ROM hack

Actually that's fine because getting rid of the code for the second controller is of no consequence really. But yeah, I've been meaning to learn all this, it's just that when I think about how much stuff there is, suddenly there's no wonder why there were so many people developing a single game. I j...

Re: Getting around the DPCM bug in a ROM hack

The problem isn't that I have no idea what I'm doing. I've been hacking for what...4 years now? The problem is that when I wanted to actually practice 6502 asm, I could never find any assembler that worked for me. They're either all DOS or x32 based, so I can't really run them at all, or they're lik...

Re: Getting around the DPCM bug in a ROM hack

Alright guys, sorry for wasting everyone's time. This is clearly not for me. I've spent the last 3 hours fiddling around and nothing worked. I don't have proper assembly tools, nothing's working on my computer, I can't translate any code to hex properly, and I wish I could punch someone right now. I...

Re: Getting around the DPCM bug in a ROM hack

This would be for a romhack basically. It's quite simple. Bank $1F is always loaded to $E000-$FFFF and never once swapped. There's enough unused junk data here for me to replace, although most of the are in very inconvenient spots, as I can only read from every 64th byte. There's enough space for a ...

Re: Getting around the DPCM bug in a ROM hack

Do you have a disassembled listing of the existing controller reading routine, starting where it writes to $4016? Yeah I have a "complete" but mostly undocumented disassembly for Megaman 3 that I found. I hope this is the right thing. I just simply located where it writes to $4016 (and reads from a...

Getting around the DPCM bug in a ROM hack

Hey people! I'm fairly new to 6502 programming in a sense, that I've never actually used proper tools to make anything, hopefully that'll change! I've been into ROM hacking for quite a while though, and the next step requires me to be here pretty much. I want to modifiy the sound engine made by Capc...
