As RM-units are becoming more and more affordable on websites like Ebay, I decided to contact Casio support in order to send me the RM-AFX update package because the original website is no longer available (http://web.archive.o...mfx20_plus.html).
I compared the new RM-AFX-ROM (expanded version named UpdateCode.bin) with those Roms available here and the 1.05 one here. It seems to be different.
Furthermore, I extracted a 512k RAM(?) image from the Windows executable. It contains two interesting strings: "OS Update" and "UPDATE02.EXE". I guess, this is similar to the fx-9860G updaters which are loaded into RAM when updating the OS. That's why I named the file UpdateExe.bin
