Notes:
Z80 clocks (both) - 3.6864MHz [7.3728/2]
Z8430 - zILOG Z8430 z80 CTC Counter Timer Circuit, clock 3.6864MHz [7.3728/2] (DIP28)
68705R3 - Motorola MC68705R3 Microcontroller, clock 3.6864MHz [7.3728/2] (DIP40)
YM2203 clock - 1.8432MHz [7.3728/4]
6116 - 2K x8 SRAM (DIP24)
8255 - NEC D8255AC-2 Programmable Peripheral Interface (DIP40)
VSync - 60.0Hz
HSync - 15.40kHz
Stephh's notes (based on the games Z80 code and some tests) :
- The "Continue" Dip Switch acts as follows :
* when set to "Normal", you can continue a game from where you just lost (table at 0x2edd)
* when set to "Checkpoints", your continue round is determined from where you just lost (table at 0x2f01) :
. if you lose from round 01 to 05, you'll continue from round 01
. if you lose from round 06 to 10, you'll continue from round 06
. if you lose from round 11 to 15, you'll continue from round 11
. if you lose from round 16 to 20, you'll continue from round 16
. if you lose from round 21 to 25, you'll continue from round 21
. if you lose from round 26 to 30, you'll continue from round 26
. if you lose from round 31 to 35, you'll continue from round 31
. if you lose from round 36, the game will become bogus because table is only 35 bytes wide
and [0x2f01 + 0x23] = 0x6c which is not a valid round
Round is stored at 0x800c (range 0x00-0x23).
