First of all thanks zillions to whoever contributes, closely or remotely to LibRetro! Bringing emulation closer to the masses is a very noble task, and you’re doing great!!
I am experimenting with RetroArch on the Ambernic RG350. Followed guides such as https://retrogamecorps.com/2020/12/24/guide-retroarch-on-rg350-and-rg280-devices/ and others.
All is nice and rosy: NES, Megadrive, PCEngine run fine. SNES also (if i disable rewind… ;)). Even NeoGeo works like a charm
BUT… (there is one) when trying to load anything with the FBA CPS1, CPS2, or Mame2003, i got this annoying black screen saying “Unsupported video mode”
sometimes for a 384x224, sometimes others… Isn’t there supposed to be some scaling of some sort? What am I doing it wrong? I tried modifying all parameters in “scaling” to no avil… i am now running a bit in circles. Is there something to configure with the cores that i missed? Or is there no down-scaling (the RG350 is a 320x240 screen i think)?
Thanks for any help telling me where to look and how to make that work!
