jrpacman.c

0.24 [Nicola Salmoria, David Caldwell]


NOTES:

- Jr. Pac-Man encryption PALs garble bits 0, 2 and 7 of the game ROMs. The encryption scheme is complex (basically it's a state machine) and can only be faithfully emulated at run time. Decryption table provided by David Caldwell. For an accurate reproduction of the encryption, see jrcrypt.c !


VIDEO HARDWARE NOTES:

- Jr. Pac Man has two 256x4 palette PROMs (the three msb of the address are grounded, so the effective colors are only 32) and one 256x4 color lookup table PROM.
