If you want cracks of Linux native games, Razor1911 is the only guy I know who does them. You're going to have to resort to GOG releases or break out a bottle from the cellar otherwise. As to finding the games, as mentioned in >>392
, try out qbittorrent's search feature, and reddit.com/r/piracy (I know it's reddit, but its wiki is quite comprehensive).
I can give you some good advice when it comes to this: do not get CODEX cracks. They use VMProtect, which obfuscates their cracks' code to prevent people from doing reverse engineering on them (megapropietary software, if you will) and because of this, games with their cracks don't work at all under Wine. I'm not sure what's the deal with Fitgirl, but
repacks don't decompress fully and get hard stuck halfway through installation. Nobody mentioned any possible cause for this, but they never worked for me and for many people. This was for older Wine versions (late 4.x, early 5.x), Wine moves rapidly so feel free to try both of these out on the newest versions, but don't expect them to work.
