Broken or no Bios file Download?

Hello. I just got a qmtech board and I did install mister fusion and then I did the update all script.
It downloaded some of the Bios roms, but not all of them and many systems gave me corruptions or do not run at all.
I did a fresh install on a small sd card today, but now it can not fetch any bios files.

After getting some bios files from the internet I could fix all but GBA, PSX, NES. GBA and PSX show me the boot screen in a currupted way. NES does not like FDS games and many mappers seem to be broken like MMC3 for example.

Is there a dat file to compare my roms with the ones needed for mister?

Edit
I did do another fresh install. No changes. I can play arcade cores that need the sd ram all day long and it passes at 160mhz
Now I picked some older cores from the github pages, but still the same. It must be the bios files or some general system corruption.

Robert didn’t mention it, but I actually provided him with my copies of the bios files for those cores that work fine for me, but they don’t work for him. Not sure of what the issue could be.

Yeah granny sent me some of the bios files. But that only fixed saturn, tg16 and neo geo cd. His neogeo pocket, gba and gameboy bios did not work for me.
I eventually found a working neogeo pocket rom and a gameboy color bios. But I can not fix gba and psx for some odd reason. Like I said i'd like to have a dat file or something to compare.

Yeah, it's really boggling my mind because the files I provided all work just fine on my MiSTer :|

Single GBA instantly freezes with a white screen after the gba boot logo. On dual GBA the second player just works.

I did the ram test at lower frequencies and it fails at 140 and lower depending if both ram modules are used or not. 150 and up is completely stable. Electronics are weird sometimes, i guess :roll:
