I seem to remember I was able to get this game to work in WinX68kHighSpeed_eng.exe in the past, but I downloaded the BIOS and the emulator afresh. I put them in one folder and insert both disk images in their respective drives.
Instead of the game starting, i get some error message about PCM1 and a missing file -- in Japanese of course. (screencap attached)
If you have managed to get this game working in the emulator, I would love to hear from you!
Thanks!
