0.62 [ElSemi]
WIP:
- 0.184: Use 4-way joysticks for Bouncing Balls [AJR].
- 0.183: brizzo and TeamEurope dumped MC68705R3 for clone Bouncing Balls (Adult). Confirmed MC68705R3 bootstrap program matches Bouncing Balls (Adult) M68705R3 [brizzo]. Hook up protection MCU in clone Bouncing Balls (Adult), added MCU to parent set as BAD_DUMP. Note: Uses a similar scheme to Pushman, but doesn't use port D on the MCU, and uses the same endianness for MCU reads/writes (Pushman swaps the bytes on writes). As an aside, Bouncing Balls has at least partial nudity in it as seen in attract mode, although less than clone Bouncing Balls (Adult). Also Bouncing Balls is the most criminal under-utilisation of a MC68705R3 ever. It uses none of the features the R family has over the P family (second interrupt, port D, ADC, wider port C), and it barely has any program code in it at all. It's barely a "protection" program either, as it has no hidden state variables, and no internal tables. It really does just produce a 16-bit response by doing a trivial manipulation on a 16-bit input. ElSemi's simulation was almost perfect [Vas Crabb]. Added MC68705R3 (4MHz) CPU3.
- 0.182: M68705 cleanup and modernisation. Split out bballs and pushman state classes. Use derived memory maps rather than installing handlers in init members. Simplify protection MCU simulation in Bouncing Balls using pushman hookup as a guide. Bouncing Balls appears to use a simpler single-word arrangement for messages from CPU to MCU, perhaps so it can use a 28-pin MCU (pushman MCU receives the command byte on port D, which the 28-pin parts lack) [Vas Crabb].
- 0.154: System11 and The Dumping Union added clone Bouncing Balls (Adult). Changed VSync to 60.080000 Hz.
- 0.141u1: Brian Troha added DIP locations to Pushman driver.
- 0.137u3: Fabio Priuli added driver data class and save states to the Pushman driver.
- 0.131u1: Angelo Salese merged memory maps in Pushman driver.
- 0.62: ElSemi added 'Bouncing Balls' (Comad 1991).
- 6th August 2002: Stephane Humbert fixed most of the dipswitches and input ports in Bouncing Balls.
- 22nd July 2002: ElSemi figured out the protection in Bouncing Balls and added it to the Pushman driver.
- 24th June 2002: Guru - Got a Bouncing Balls (Comad) board from Taucher.
