Well, i can't seem to tweak it to make it look like Mednafen...
I might end up simply using pre-calculated values from the 512-color test lol.
I don't know the problem, but when I try a CD game, the screen turns black and nothing more.
I put the syscards in the .temper\syscards directory , I need something else?
Your game needs to be in bin/cue or iso/cue format.
Check the cue file, it needs to be valid and the filename is case-sensitive,
you might have to modify the cue file.
The syscards file needs to be named "syscard3.pce", make sure that's the case.
I myself tried it just recently (last version) and i can assure you CD games work perfectly.
Also... if you use Filezilla, you need to change the transfer type.
To do so, go to Transfer -> Transfer Type -> Binary.
Then delete your iso and transfer it again to your console.
I'm sorry but i know a lot of people who suffered from that issue and it turned out to be Filezilla's fault.
A MTP implementation to the Zero should fix this but it won't be added any time soon.
