0.87 [Angelo Salese]


WIP:

- 0.147u2: Miodrag Milanovic modernized some static calls in Alien Command driver.

- 0.140: Angelo Salese rewrote Alien Command irqs by not using cpu_getiloops() function.

- 0.131u2: Angelo Salese fixed background colors in Alien Command.

- 0.128u2: Angelo Salese fixed sound, hooked-up generic inputs and added some notes in Alien Command (not yet working). Added 2nd Player, button 1 and 2x coin slots. Changed clock speed of the 2x OKI6295 to 2112000 Hz. Added dipswitches 'IN0', 'Ticket Dispenser - 1/2' and 'IN2'.

- 0.87: Angelo Salese added 'Alien Command' (Jaleco 1990). Parts of the hardware still unemulated.

- 16th November 2003: Angelo Salese - It's a modified NMK16 board, current emulation got stuck due to some problems with the motor interface(as you can see from snap 3) and there are some video issues, snap 3 has wrong colors due to a scroll register not hooked up. Nothing really un-fixable though...
