So I'm building up my collection of roms. I'm on a mac and as far as I know there are no Goodmerge tools for mac, so I'm unzipping everything and deleting the regions, languages and other games I don't want before rezipping.

However there are a ton of hacked roms for some of the more popular games. Making games is hard so I assume the vast majority are crap, but there has to be some gems in there.

What are some of the worthwhile roms. Any system is ok as I've got a huge hard drive and downloading complete collections.

Pic probably not related, but watching video of it made me realize some people are actually putting effort in to these.
