BallyFA - a Bally MPU based on a low cost FPGA
This is a 1:1 functional replacement to a original Bally MPU, without the additional features of a LISY35, but with much faster boot and lower costs. You can build a BallyFA for less than 50 Euros!

components needed:
- preassembled PCB (see section 'how to order your BallyFA PCB' below)
- FPGA plus USB Blaster, see here
- a few other 'standard' components, see Reichelt shop cart below
- the program ('pof file') for the FPGA
- the Bally Roms on a micro SD card (see 'SD card image' below)
At the moment 49 different Bally Games and 4 Stern games along with their 'free play' and '7digit' variants ( 128 in sum) are supported and can be selected via Dip switch 'Game Selection.
For each game BallyFA all software settings, Highscores, .. are stored independently.
Note: Pin Headers in the Reichelt shop cart have 11mm height. For better contact use Pin Headers from Digikey with 13 mm height. Digikey Part: WM50017-36-ND
