- Don't mix ROMs for different platforms - use generic BASIC with generic KERNAL, Mega65 BASIC with Mega65 KERNAL, etc.
- Don't mix these ROMs with any other ROMs; the only exception is CHARGEN, this one is fully interchangeable.
- Don't mix these ROMs with any other ROMs; exceptions:
- kernal_hybrid.rom, which is meant to be used (and has to be used) with the original BASIC ROM;
however, this hybrid ROM cannot be distributed due to legal/copyright reasons
- chargen.rom - this one is fully interchangeable
- Don't mix ROMs from different builds/versions (again, CHARGEN is an exception).
