The monitor built into the Final Cartridge III is one of the best ones for the C64. Some of its unique features are:
- dumping PETSCII (
Icomand), character sets (
EC) and sprites (
- F3/F5 for scrolling, including backwards disassembly
- drive mode (
OD) to view and change RAM of a drive and execute code there
The monitor’s biggest weakness is its lack of support for illegal opcodes. I have now added this support.
The source is available on github:
See the build instructions there on how to enable illegal opcode support.
