- RAM command now has CART option. displays any additional RAM the
cartridge may have
o cartridge
- implemented RAM() command. returns copy of RAM array
- save/restore banks functions are now save/restore state and deal
with cartridge RAM in addition to bank information
o debugger/memory
- better error messages for peek and poke
