Chip-8 Emulation Problems Options

[CJ Master]

Hello there, It's been a long while since I've been on these forums. I hope you fine people will be able to help me out.

I rewrote from the ground up Bathy's intriguing Chip-8 emulator with an easier to read coding style, and by the time I release it It should be very well commented.

Bathy's Emulator and a public domain rom can be downloaded at: http://gmc.yoyogames.com/index.php?showtopic=331812

The problem is I must have goofed somewhere, and I'm rather convinced that it's the pointer. Regardless, I could use any advice on how to fix the error at the start of the program.

(Please note that in order to test it you need a Chip-8 rom, there are plenty in the public domain for you to grab.)

Ill try too see the problem.. I have made my own Chip-8 emulator based on Bathy's example, but never got arround to getting it released. Ill edit when I found it

EDIT:
Ok, well, because you changed a bunch of variables, you weren't carefull and changed one of them to one that was already there... This messed up the whole drawing/loading of the rom.

Here is a fix of your example, but the format and the comentary is gone because I was copying and pasting them from Bathy's example, but it works fine now

And here's my NxtChip that I never released:


EDIT2:
I axcidentally uploaded yours with the same name as my other one, so now it seems like your has 4 downloads
