Issues:
- not all games work due to either banking, dma or protection issues.
- graphics are glitchy in some games.
- kartduel needs a redump to fix "BSOD" issue. Graphic data is corrupt which is causing the game to throw an error internally causing the BSOD.
- kartduel frame rate is choppy, it freezes every half second
memo: this is due to the link PCB not being implemented, it keeps trying to communicate over the network causing hitching.
Forcing 0x1f781701 (which is within the shared RAM between the PCBs) to 0xff will stop the hitching.
