Thanks to Gaijin Punch so do i now have the G.I.M.I.C (MB2) and also OPM, OPNA and OPL3 sound boards
It took a while to figure out how to update the firmware as the instructions is in japanese, but i finally got it to work.
I have tested Gimic with a Dosbox build that support that play the OPL2/3 music thru Gimic instead of being emulated, and also Hoot support Gimic with all available sound boards.
Here is a pic of Gimic in action (with OPNA installed)
Thanks again for the help Gaijin Punch
