Jackpot Cards / Jackpot Pool (c) 1997 Electronic Projects

driver by David Haywood & Angelo Salese

Notes:
-There's a "(c) 1992 HI-TECH Software..Brisbane, QLD Australia" string in the program roms,
 this is actually the m68k C compiler used for doing this game.

TODO:
-Correct NVRAM emulation (and default eeprom too?), you cannot save settings to the EEPROM
 right now, also remove the patch (it doesn't boot otherwise);
-UART;
