Yes I used it with EP32, when I developed the version 4.1 ROM.
But not to many fun in this action, because no hw emulation
Egzo promised hw emulation of the Emulator will coming in future version of EP32!
Because this project started, but not finished yet, the version 1.20 of EP32 will hang up with the emulator ROM.
The 1.19 is able to run without the hw
I put a cheat in the version 4.1 ROM
when the ROM wait for the hw, then press the up&down keys, and the ROM is starting without hw.
You can use the BASIC, but because no color emulation, you can't change the colors.
Possible to load programs, but the most of games will hang up, when using the Spectrum hw.
Some programs (for example: Pogo) use only ROM routines for keyboard scan, sound, etc. These programs works, but without color emulation...
