That's not quite a Rom Pack. I think xmodesty wants a single download that contains all the roms, or groups of roms.
my 8820 NES rom collection w winrar compression only 254mb... my 6766 SNES rom collection w 7z compression only 1.71gb... so older console is possible but newer console is huge...
Why don't you make it yourself, just add games you want to a .zip or .rar of .7z or whatever. I do that to back up my favourite roms and huge roms. So when I delete them I don't have to re-download
