[17BII] Olivier De Smet's android emulator app

Christoph Giesselink's FILETOOL set of utilities is made for doing exactly what you're asking about, converting between various ROM file formats. It's available here:

I'm not 100% sure this is the problem you have, but they're easy to use and it's simple to try it.

Also, I had problems getting Olivier's go27S emulator to work until I moved the ROM file from SD card storage to main RAM storage (the downloads folder works as well as the intended folder). BTW, that file is 64KB in size, so the 17BII ROM is likely the same size; yours seems to be a non-std size?
