[comp.sys.handhelds] Chip-8 ... PLEASE HELP

mueller@schaefer.math.wisc.edu (Carl Mueller) (05/21/91)

I have a couple of ideas for chip-8 games but am having trouble getting
started.  I have a couple of questions for anyone out there who can help.

1) What assemblers do you recommend?  (I have an AMIGA and a C compiler,
but no PASCAL compiler, so chipper is out unless someone can compile it
for me.)
2) I tried to disassemble (by hand) a simple chip program (namely the CT2
program that is an example for SUPERchip).  I can pretty much follow what is 
going on, but I don't understand the operations that begin with '0'.  These
are the "Call 1802 machine code subroutine at NNN" operations.  Can you be
of any help?  What are the 1802 machine code subroutines???

Thanks for any and all help.
