In the 90’s I used to have a FM-Pac, to add great sound to my MSX. The built-in menu was Japanese, and since there was no Google Translate, it was pretty useless to me.

Thanks to MSX Translations there is a patch available to patch the ROM to English. This patch can be applied at runtime, but I used it to patch the original ROM and burn the patched ROM on a new Eprom and place it inside the original FM-Pac.
To accomplish this I removed IC2 from the original FM-Pac and replaced it with a 27C512 Eprom (150nS), with the English Patched Rom.

I have dumped the original ROM and patched it with the English patch, they are available as download on msxinfo.net:

This archive contains the original Japanese ROM and the translated English ROM Japanese...
After replacing the ROM, this is the result:

Great job! Thanks for sharing! :o)
