I realized today the last time M1 and its frontend BridgeM1 were updated is one hundred years ago sans a zero and it has been so long some people here might not even know about it. M1 is an arcade sound emulator by R. Belmont. You can play arcade music by itself in player. The frontend for it BridgeM1 is made by Fujix.
I put a rar of the last group of merged downloads attached. You can download it and extract it into a folder and open bridgem1.exe. This is what the default looks like but you can change the skin:
Put roms in the roms folder or change the path in the ini files you see. If you have issues post them on the correct message boards. I'm just trying to introduce more people to the programs, not trying to be tech support.
