The driver has the preliminary status and can not load the internal splitted ROMs (black screen). Maybe the addressing for the ROM initialization is wrong?
If I merge these ROMs (32KB) I can use it on Takeda�s EPSON HC-20/HX-20 emulator.
If I use F.J. Kraan�s hex dumps and merge them together it works on Takeda�s emu too. Of course after the hex to bin conversion.
