Thanks 
Here's some public domain roms (not all work yet)
http://www.zophar.net/roms.phtml?op=show&type=chip8
Btw anyone can use this code however you want (help is more than welcome also), PB needs a good and solid open source chip8 emulator for everyone to learn from.
Here's a bit of info if anyone is interested
- There are 16 registers from 0-15 register(X)
- Register(15) is the cary register and collision flag
- I is another register mostly for memory access
- chip8 mode is 64 x 32 while schip8 mode is 128 x 64 (scaled to the window)
- The stacksize only allows for 16 subroutine calls
- All graphics are XORed onto the screen
- I do not use wrapping (as the documentation suggests) since only 1 game uses it (that I know of) and it causes problems in some games. Most games that that need it, handle it themselves.
- The rom starts at $200 since the first 512 bytes is reserved for the interpreter.

Added the gui and updated to 0.2.. Unfortunately, not much in the way of bugs have been fixed (just some small things)

Already done by balrog(part of it), but nobody has the source anymore.Pantcho!! wrote:Awesome!!!

Yup, gameboy is next for sure. will probably take a very long time since the z80 processor has faaar more instructions than chip8. Anyone interested in helping?
Ps: updated to 1.0, almost every game works now.

If you want, I can check my PB code archives. I am pretty sure that is on one of my CDs in the Balrog section. I also have the code for an open source GameBoy emulator written in VB.Already done by balrog(part of it), but nobody has the source anymore.

Here is his gameboy emulator
Very incomplete though.
Now that this emulator is almost done, does anyone want to help me with writing a gameboy emulator?
Im probably going to start mapping the z80 instructions today
Edit:
Updated to 1.1, almost perfect compatibility now. Even more games work perfectly like joust. Check the changelog.

Nice to see the sources again .

Well guys, I probably wont be updating this much more (except for some visual changes or if some wierd bug creeps up).
I have started work on my z80/gameboy emulator. If someone wants to join me that would be more than great.
