+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
