I was working on a Roland KR-370 that had been through a lightning strike, and I was looking for the BIN file to program onto a replacement EPROM (IC2). I did eventually find one, posted by a very helpful individual in the Badcaps forum.
During my search, I encountered several enormous repositories of EPROM dumps (such as this one at dbwbp.com, which is worth checking out), and decided to reproduce them on my website, should anybody need one. They’re listed below, and all ROMs are mirrored on my MEGA drive.
