CHIP-8 virtual machine emulator - Load chip8 ROMs in the prime
My emulator is a very poor implementation, use Mark's CHIP8 app available here: http://www.hpmuseum.org/forum/thread-475...l#pid39757
___________________________________________ Hi! Here is a small tease of the emulator: With the upcoming Primecomm version loading any chip8 ROM will be just like sending the rom directly with on-the-fly conversion  CHIP-8 is a very old simple language/virtual machine: http://en.wikipedia.org/wiki/CHIP-8 Only 4K memory, but great start point into emulation! Here are some ROMs: PONG2 Code: local b5:={#22h,#FCh,#6Bh,#0Ch,#6Ch,#3Fh,#6Dh,#0Ch,#A2h,#EAh,#DAh,#B6h,#DCh,#D6h,#6Eh,#00h,#22h,#D4h,#66h,#03h,#68h,#02h,#60h,#60h,#F0h,#15h,#F0h,#07h,#30h,#00h,#12h,#1Ah,#C7h,#17h,#77h,#08h,#69h,#FFh,#A2h,#F0h,#D6h,#71h,#A2h,#EAh,#DAh,#B6h,#DCh,#D6h,#60h,#01h,#E0h,#A1h,#7Bh,#FEh,#60h,#04h,#E0h,#A1h,#7Bh,#02h,#60h,#1Fh,#8Bh,#02h,#DAh,#B6h,#60h,#0Ch,#E0h,#A1h,#7Dh,#FEh,#60h,#0Dh,#E0h,#A1h,#7Dh,#02h,#60h,#1Fh,#8Dh,#02h,#DCh,#D6h,#A2h,#F0h,#D6h,#71h,#86h,#84h,#87h,#94h,#60h,#3Fh,#86h,#02h,#61h,#1Fh,#87h,#12h,#46h,#00h,#12h,#78h,#46h,#3Fh,#12h,#82h,#47h,#1Fh,#69h,#FFh,#47h,#00h,#69h,#01h,#D6h,#71h,#12h,#2Ah,#68h,#02h,#63h,#01h,#80h,#70h,#80h,#B5h,#12h,#8Ah,#68h,#FEh,#63h,#0Ah,#80h,#70h,#80h,#D5h,#3Fh,#01h,#12h,#A2h,#61h,#02h,#80h,#15h,#3Fh,#01h,#12h,#BAh,#80h,#15h,#3Fh,#01h,#12h,#C8h,#80h,#15h,#3Fh,#01h,#12h,#C2h,#60h,#20h,#F0h,#18h,#22h,#D4h,#8Eh,#34h,#22h,#D4h,#66h,#3Eh,#33h,#01h,#66h,#03h,#68h,#FEh,#33h,#01h,#68h,#02h,#12h,#16h,#79h,#FFh,#49h,#FEh,#69h,#FFh,#12h,#C8h,#79h,#01h,#49h,#02h,#69h,#01h,#60h,#04h,#F0h,#18h,#76h,#01h,#46h,#40h,#76h,#FEh,#12h,#6Ch,#A2h,#F2h,#FEh,#33h,#F2h,#65h,#F1h,#29h,#64h,#14h,#65h,#02h,#D4h,#55h,#74h,#15h,#F2h,#29h,#D4h,#55h,#00h,#EEh,#80h,#80h,#80h,#80h,#80h,#80h,#80h,#00h,#00h,#00h,#00h,#00h,#C0h,#C0h,#C0h,#00h,#FFh,#00h,#6Bh,#20h,#6Ch,#00h,#A2h,#F6h,#DBh,#C4h,#7Ch,#04h,#3Ch,#20h,#13h,#02h,#6Ah,#00h,#6Bh,#00h,#6Ch,#1Fh,#A2h,#FAh,#DAh,#B1h,#DAh,#C1h,#7Ah,#08h,#3Ah,#40h,#13h,#12h,#A2h,#F6h,#6Ah,#00h,#6Bh,#20h,#DBh,#A1h,#00h,#EEh};local
