Hi,
first at all i am a professional amiga-user (coding, elctronics and all that s**t).
I went over to retropie4.1 for a testrun with uae4arm v0.5.
In my opinion, it makes sense to integrate the emulator now. The basic configurations and scripts could be tested in this way. The emulator could become even faster, but some titles can be played well. The CD32 emulation with the correct ROMs is able to start correctly from ISO files. All necessary buttons can be mapped onto an XBOX controller. The CD32 does not need a keyboard or mouse. For those who would like to test a workbench on the CD32, I can recommend the "cd32wb_r1.iso". (Hllp: //helenvivet,free,fr/Pegasos/cd32wb_r1,zip)

The CD is very useful for testing, on the Amiga side the mouse is mapped to the joypad and there is a screen keyboard. Regardless, connected USB mice and keyboards also work. A full use by controller is given in any case.
On the subject of speed, the graphic output of the Customchips is still very slow, despite various test settings (352x256 + frameskip), but the CPU emulation is fast. Example: An installed workbench with graphics card output (Picasso96 on "bigbox" Amiga4000-setting) is really useful, but this is not our target....
In summary, I would welcome an experimental integration into Recalbox.
For any inquiries, I'm willing to help.
