Just leaving this here so that it won't get lost... (I just had to continue after seeing the alternative) EDIT: Removed (outdated)
Lots of work done, testing disk files, downloading equivalents with different names, checking websites and even looking at eBay listings (I even found something inside a compilation which wasn't listed at WoS). So right now the "Games" list is still WIP, but others (including "Compilations - Games", which probably includes most of the system's catalogue) may be fine already.
