@myst I guess it‘s because i just copied backgrounds and sound. did not want to replace too much, as i didn‘t want system pictures, etc. change to pcenginecd. i‘ll try, thanks for info.
as these rating files are so small, i’m wondering even more about a weird problem i still have: when i quit an emulator, ONLY these rating graphics are white blocks for a short time sometimes... after not more than one second when left emulator, they are shown properly again. on the other hand no problem with other, big graphics like backgrounds. so can‘t be a memory issue all. maybe an es-thing?
it‘s the only disturbing issue left, everything else is fine now, both with theme 1.0 and rb 6.0. maybe @paradadf has an idea?
