Games on this hardware are becoming incredibly hard to find...
Having finally managed to get a working boardset after a long and costly struggle I've decided to design a multi kit.
All ten M72 games are supported:
- Air Duel
- Mr. Heli/Batlle Chopper
- Dragon Breed
- Daiku no Gen-san/Hammerin' Harry
- Gallop/Cosmic Cop
- Image Fight
- Legend Of Hero Tonma
- Ninja Spirit
And there's even room for few more titles (M84 conversions, who knows?).
Of course I had to patch games first:
- R-Type to run on the 'standard' M72 romboard
- All other games to get rid of the security chip
- Dragon Breed/R-Type/X-Multiply to use the same memory map as other games
Here are the routed PCBs:
Looking forward to doing more tests when receiving PCBs but I expect some problems regarding sound samples playing for some games (should be fixeable with some more ROM hacking).
