On my MSX1 days with games in cassette tapes, I moved all of them into floppy disks directly in the MSX computer. (a Brazilian MSX 1.1 Gradiente).
First, the game had to be loaded into the MSX's RAM with RUN"CAS:" but without the ,R parameter to actually run the game. Then I would simply type another command to save the data from RAM as a file, directly into a floppy disk (I don't remember the commands). It was the only way to convert the cassette game into a file.
It was a BSAVE command with start/end memory addresses, I think. I don't remember exactly what it was (it was the late 80's).
I don't know how these .cas files in MAME we have today were converted.
