You will probs need to change the roms to change the JP,.
I do know the 10p / £4.80JP token roms have been dumped and are available @ MPU Mecca.
As for the chuzzy kit, I am pretty sure it can be run to work in normal game mode, but still allow you to change stake / price of play options.
Contact Ron (BF74) @ MPU Mecca, as he's worked with Chuzzy kits before, and I believe he has access to all the software etc.
Failing that, gimmie a shout, and when I next pop in and see Chuzzy in Nottingham, I'll find out what all the options are on that dog-bone board.
DO NOT sell this board, because trust me when you come to sell the machine, it will be worth a lot more with one of those Chuzzy kits fitted.
