LouisB Posted August 21, 2022 Share Posted August 21, 2022 (edited) I'd like to modify (hack) VIC-20 Cartridge "The Count" into a "Sky Blazer" cart by replacing the ROM with an EEPROM burned with these 8k images: Sky Blazer (1983)(Broderbund)(NTSC)[multipart].crt Sky Blazer (1983)(Broderbund)(NTSC)[A000][multipart].crt I've verified these images work in Vice emulation using "Add to generic cartridge..." 4/8/15KB image at $6000 and $A000 Cart w/ Original ROM Other side of PCB Understand that $A000 is the 8K cartridge space. Is some memory mapping required to access the other 8k image in $6000, or can I just burn the two sequentially into a 16k eeprom? Appreciate any VIC-20 guru comments!
