Game's ROM.



MAME Info:

0.128u2 [Roberto Fresca]


WIP:

- 0.135u2: Angelo Salese bypassed the RNG test in Joker's Wild, implemented bare minimum to allow it to go into gameplay and fixed tilemap graphics. Fixed gfx1 rom loading. Changed M6809 CPU1 clock speed to 4MHz. Added dipswitches 'sw1', 'sw2' and 22x 'Unknown'.

- 0.128u2: Roberto Fresca added Joker's Wild (encrypted) (Sigma 1988). Game is trying to boot, and after approx. 90 seconds an error message appear on screen: "Random number generator is defective", then stuck at $9859. PIAs are commented out just to see the R/W on error log.

- 39th October 2008: Roberto Fresca - Fixed graphics to 2 bits per pixel.

- 25th October 2008: Roberto Fresca - Initial release. ROMs load OK. Proper ROMs decryption. Added MC6845 CRTC. Video RAM OK. Added technical notes.
