Thanks for all the comments!
@robcfg: I don't have a precise list at the moment, but AFAIR you could check some clones for MSX, MSX2, ZX Spectrum and basically everything else added to la(te)st MESS.
@The Flying Ape: You are right. But Everything in that area WAS ok some time ago. But the names and/or clone-parent relationships were changed in the meantime, so I will have to correct filenames to make it proper again... Thanks for pointing this out!
@Trebor: Basically I try to respect PAL/NTSC (or rather US/Eu/Jp/etc.) difference, but this is not always the case. Sometimes I just show diferent case versions - just to show them - like C128. Or when I'm simply not sure. So... ehm... what IS the difference in A7800 case? Will be happy to correct it if you point me in right direction...
BTW - I just tried to go through CBM line - unfortunately it's a bit of a... you know what.
I think that those localized clones may become just BIOS selections at some point, so I'm not cloning exactly same pictures for them (at the moment). Any comments regarding this?
