Information on mouser

0.65 [Frank Palazzolo]


- AY-3-8910 initialisation not correct. MASH (ID 03732)


- 0.142u3: Angelo Salese removed deprecat.h dependancy and updated irqs accordingly for Mouser.

- 0.141u1: Couriersud improved NMI handling in Mouser.

- 0.136u4: Fabio Priuli added driver_data struct and save states to Mouser.

- 0.131u1: Angelo Salese merged memory maps in Mouser.

- 0.112u1: Mamesick fixed sound cpu interrupt on write (mouser_sound_interrupt_w).

- 0.65: Frank Palazzolo added Mouser (UPL 1983) and clone (Cosmos). Known issues: This driver was done with only flyer shots to go by. Colors are a good guess (might be perfect). Clock and interrupt speeds for the sound CPU is a guess, but seem reasonable, especially because the graphics seem to be synched. Sprite priorities are unknown.

- 8th February 2003: Frank Palazzolo completely fixed the cocktail mode in Mouser.

- 7th February 2003: Stephane Humbert fixed the inputs and dipswitches in Mouser.

- 6th February 2003: Frank Palazzolo sent in a driver for Mouser.

- 25th October 1998: J-ROM dumped Mouser (UPL 1983) (Universal Play Land).
