Hi
Sorry for this, i told to @arkive to open a new thread for C64 emulation.
I know Recalbox doesn't support Commodore 64 but i think i can answer beacause all i will said will work on Recalbox and others OS.
1st, you can use 320x200 resolution (the C64 max resolution) but it's better to use a 1920 (ou 1600) horizontal resolution for screen setup.
Commodoire 64 have a 200 lines vert(ical resolution but if you want overscan color background, you must open a 240 lines screen.
I use this timing because screen can be horizontaly "zoomed/unzoomed" and moved. Screen can be verticaly moved too.
To "zoom/unzoom" horizontaly, you must setup you CRT to do this.
Due to Rpi Pixel clock limit, if you use a 320x240, you can't do anything (zoom/position)

VICE binary and configfile are in :
/recalbox/share/emulators/combian64/
ALL other VICE files are in :
/recalbox/share/emulators/combian64/vice/
(it's because i use combian C64 version and i choosen the parent folders)
And for config file :
*** NTSC ***

FOR PAL, you just have to delete this line:
MachineVideoStandard=2
And use 288 lines :
SDLCustomWidth=1920
SDLCustomHeight=288
SDLWindowWidth=1920
SDLWindowHeight=288
The command line :
/recalbox/share/emulators/combian64/x64 -config /recalbox/share/emulators/combian64/config.cfg -autostart "/recalbox/share/roms/c64/Bubble Bobble.d64"
That's all
No support here.
If you can't launch C64, VICE must be correctly installed.
