PONG rom about chip8

[wernsey]

Hi, which ROM are you referring to? Can you attach a file so that I can take a look?
Thanks

Attached is the ROM I was referring to. I had the same problem in my emulator and I found the problem was within my implementation of the opcode 0xFx65 where I was only loading contents from memory Location I+x to V[0]-V[x-1] opposed to V[x]. I'm not sure if the issue is the same for you though.

I've disassembled the ROM and then annotated it so that I can see how the program works.

The annotated disassembly is attached here:
PONG.asm.zip

I then ran the ROM on my emulator with the built-in debugger. It seems the problem is in my implementation of the Fx33 instruction that does not properly break the score down into its BCD digits

@jakears93 It turns out it was my implementation of the Fx65 that did the same thing, copying one too few bytes. I will upload a fix shortly

I pushed my fix
