Here we emulate the base configurations of these two boards:
MegaCart+ = up to 512K (31 banks at $8000, 1 at $C000) of ROM and 2 x 16K RAM @ $4000
VersaBoard = up to 256K of ROM and 2 x 16K RAM

TO DO:
- investigate whether the POKEY detection routines in homebrew do fail due to emulation
issues or not
