- Inputs slightly wrong for the LCD games. In those games, start 1 begins a 2 players game. To start a 1 player game, press flip (X).

- Animation in bijokkoy and bijokkog (while DAC playback) is not correct. Interrupt problem?

- Sampling rate of some DAC playback in bijokkoy and bijokkog is too high. Interrupt problem?

- Input handling is wrong in crystalg, crystal2 and nightlov.

- Some games display "GFXROM BANK OVER!!" or "GFXROM ADDRESS OVER!!" in Debug build.

- Screen flip is not perfect.


- The blitter can copy data both in "direct" mode, where every byte of the source data is copied verbatim to video RAM *twice* (thus doubling the pixel width), and in "lookup" mode, where the source byte is taken 4 bits at a time and indexed though a lookup table.

- Video RAM directly maps to a RGB output. In the first version of the hardware the palette was 8-bit, then they added more video RAM to have better color reproduction in photos. This was done in different ways, which differ for the implementation and the control over pixel color in the two drawing modes.
