I hope you don’t mind and can forgive me if I hijack this thread. Unluckily I can’t create a new one and I must share my pain hoping in some support
I have got a rpi 4 and bought it mostly for mame. Since retropie isn’t ready yet I have focused much of my time on lakka with disappointing results
I use pinn and I have installed it regularly . Initial experience was great. I had more troubles finding working roms than making lakka working. It indeed worked out of the box.
With my first roms everything worked great on my 4K tv. I really love the CRT geom shader and the game looked great with it and I could play fine.
Hence I looked for more roms. When i finished and returned to lakka some days later, something wasn’t right. I couldn’t enable the shader anymore without dropping the frame rate to 8fps. Couldn’t figure out why ,but I also realised that that poor gpu would have a hard time with the fill rate at 4k. I spent hours to try to figure out how to reduce the resolution without any results. Among my numerous tests I tried to reset the config and as result now lakka stopped to work, like if all the fundamental files have been deleted . I have now a menu with retro fonts and just few options with no way to fix it. It seems that the only solution is to reinstall everything which would also mean I got to reinstall all the other os on the card too .
Since that is quite some work I decided to install retroarch on the raspbian . It works and and can set the resolution to what I want, however I cannot figure out why after I download the cores, retroarch doesn’t have the permission to write the files to install them.
I am fine to use retroarch on raspbian too, but it may not be ready for it?
Please any advice is highly appreciated
