Great news! how you get this running ?
i have 2 another german bwb mpu4 video roms that you can test when you like.
its piccadilly nights a very funny game and miami dice but i think the programm rom in piccadilly nights is missing.
Needed some changes to the code as it uses a slightly different character chip, and also uses bank switched Sound ROMs as there are loads of samples in this game!
