MAMEWorld Forums - EmuChat - Beezer.cpp *edit*

Very useful thread revival this time around. It is a good reminder since it means the source code file can use some updating...especially the combination settings of when able to enter 'Test mode' needs to be corrected/verified etc. And also someone that has a pcb and any recording device that can take photos and do video recordings of video output from an actual Beezer pcb and post them in this actual thread later just to show what is missing or if colors are still not correct.

Notes:
- To enter test mode, hold down 1P Start and 2P Start, then reset

TODO:
- Improve sound (filters? A reference recording would be nice)
- Schematics in the sound area seem incomplete, there are
several unknown connections
- Watchdog timing (controlled by a 555)
- Figure out differences between the two sets (test mode isn't
working in beezer1, instruction screen is different)
- Verify accuracy of colors

After the game boots and you are in game over / attract mode, press and hold start1 (1) and then press F3.

Only works with set 1. Does not work with set 2.

Note, other combinations did NOT work...
press and hold start1 + start2 and then press F3 did not work
press and hold start2 and then press F3 did not work
all combinations on set 2 did not work
