Non Yamaha software for CX5M

That was the only mention of BIT2 I could find online :o

Sorry. We have quite a bit of old cassette software but none of those I don't think, I'll have to check with my dad as that stuff is all his.

That program is as old as me My dad got it free with his SFG-005 module in England but we later emigrated to Australia so I have no idea. I know that the same "AE" logo that you see in the load screen is embossed on the adapter pcb between his Cannon v-20 msx and the module so Accessories Etc. probably sold the whole lot to him directly.

I've used wav2cas.exe -np bit2.wav bit2.cas as instruction (it's very important to use the parameters -np)

The YRM-104 (FM Music Macro without disk support) and YRM-504 (FM Music Macro II with disk support) cartridges add new BASIC extensions in a similar way to the MSX-MUSIC and MSX-AUDIO BASIC extensions.

Not super common but not impossible to find… I have YRM-104 myself and I think I might also have YRM-504 (it says "YRM-501 FM Music Macro II" on the label which is obviously wrong ). The ROM of the former you can find on cx5m.net. Not sure what extra features the latter adds.
