  • Bank switching
  • More examples
  • Is there a test suite / test cart?
  • More debugging -- add display list to debug tree?
  • Two-button controllers
  • No difficulty switch?

Can you add in some bankswitching modes for 7800?
Specifically these 3-

  1. POKEY @ 800 - this isn't a bankswitching mode lol, but POKEY is something you can add to a 7800 cart so I think it should be supported.
  2. RAM @ 4000 - 7FFF
  3. 128K cartridges- Think of this as a giant $00000-$1FFFF space.
    $1FC00-$1FFFF is mapped to $C000-$FFFF.
    $8000-$BFFF can be banked by writing a number from 0 to 7 to anywhere from $8000-$BFFF. Ignore the top 5 bits.

Even better would be if you could support 512K or Bankset (seperate MARIA graphics)
