(C) 1987 Jaleco
driver by Luca Elia (l.elia@tin.it)
CPU : 68000 68B09
SOUND : YM2149 Y8950(MSX AUDIO)
OSC. : 6.000MHz 3.579545MHz
* CTC uses MB-8873E (MC-6840)
Interesting routines (main cpu)
-------------------------------
Interrupts: 1-7] d17a: clears 20018 etc.
f4b2 print string: a1->(char)*,0x25(%) d7.w=color a0->screen (30000)
f5d6 print 7 digit BCD number: d0.l to (a1)+ color $3000
Interesting locations (main cpu)
--------------------------------
20014 # of players (1-2)
20018 cleared by interrupts
2001c credits (max 9)
20020 internal timer?
20024 initial lives
20058 current lives p1
2005c current lives p2
20070 coins
200a4 time
200a8 energy
60008 values: 0 1 ffff
6000c bit: 0 flip sceen? <- 70002>>14
1 ? <-
6000e soundlatch <- 20038 2003c 20040
To Do
-----
- The sound section will benefit from proper MC6840 and YM8950 emulation
