not all games work due to either banking, dma or protection issues.
graphics are glitchy in some games.

- truckk doesn't boot: the H8/3002 never enters InitJVSBoards @ 1DE2. 1DE2 is referenced in a table of commands at 4032,
which is called by the routine at 3FEA. It is not clear how execution is intended to get to 3FEA - there are no direct
branches to that location, and the bytes 3F EA don't appear at all in the program.
- technodr: printer not emulated. To play the game, press F2 to enter the test menu, navigate to GAME OPTIONS and disable
the printer by setting "PRINTER" to OFF.
