Roberto Fresca has posted news on his MAME driver WIP for Interflip games. InterFlip is a spanish company that manufactured/exported pinballs and class ‘C’ (casino) games. The hardware is composed by two (main and sound) boards driven by a I8039 each. The video and color RAM are addressed through I/O ports and latch tricks due to the I8039 addressing restrictions. The work is mostly from Grull Osgo, and after a lot of work they have all games working properly with sound.
