Congo Bongo

0.10 [Ville Laitinen]

Samples required


- Use F2 to enter test mode, then 1 to advance from one test to the following.


- External samples for Congo Bongo are playing very strangely since the zaxxon.c driver rewrite. It broke somewhere between 0.107u2 and 0.108 but they were working perfect in 0.107u1. gorilla.wav - it should play one time at game power-on (initialize) and should play five times during gameplay (5 seconds after game startup, then always five times every time the gorilla walks off to the next stage) The rest of the samples... bass.wav rim.wav congah.wav and congal.wav are all being played but are all seriously muffled. You will clearly hear the difference between 0.113 and when they were working accurately in 0.107u1 by listening to the test modes I recorded between the two MAME versions. The recordings... startup gorilla.wav placement, attract modes, and bonus original pcb recordings are also included for reference. Thanks. congo0113gre Gyrovision


- 0.107u3: Fixed rom names and dipswitches.

- 0.107u2: Rewroted Zaxxon driver from the schematics. This is still a WIP (not finished yet) [Aaron Giles]: Fixed clock speeds and video timing. Complete memory maps. Simplified video code and merged common cases together. Palette derived from resistor weights. Background positioning still a little off. Changed Z80 CPU2 clock speed to 4MHz, palettesize to 512 colors, VSync to 59.999409 and input to 8-way Joystick. Removed ROMREGION_DISPOSE from gfx4 and changed gfx4 rom address to $2000. Added dipswitches 'Lives', 'Demo Sounds', 'Cabinet', 'Coin A/B' and 'Bonus Life.
