I found this site recently and its been an amazing tool for getting roms, which hasn't been taken down by Nintendo and such. Site runs well on old hardware, has a up to date list of games, and supports a ton of consoles, even Wii, which has helped me get games on it. Only small gripe is that I dont like how the files come in .7z or .zip. I would understand if it was because the source put them in zip files, but there is a txt file added so that is not the case. Otherwise, it is the best source for roms on the internet.
