malzak.c

0.77u3 [Pierpaolo Prazzoli, Barry Rodewald]


TODO:

- I/O ports (0x00 for sprite->background collisions)

- Sound (2x SN76477)

- Playfield graphics may be banked, tiles above 0x1f are incorrect

- sprite->sprite collisions aren't quite perfect (you can often fly through flying missiles)


NOTE:

- Malzak was produced by Kitronix, cabinet artwork suggests it was released in 1980. Was sold around New Zealand in the early '80s. Sold about 500 sets, fairly decent for the time. There are more games on this hardware, as far as I am aware.

- SAA 5050 display code "borrowed" from the Philips 2000T/2000M driver in MESS.


VIDEO HARDWARE NOTES:

- SAA 5050 for Character display (TODO: fix up background colours)

- S2636 (x2) for Sprites, Sprite->Sprite collisions

- Playfield graphics generator. (TODO: probably best to switch this to tilemaps one day, figure out banking).
