I've just started to upload some zips of some Arcade games, I'm going for 20 games a zip file, and the games vary.
On the last site there was the bonus of playing it before downloading, but opted here just to have them in individual packs, so you can unzip install, and select the categories to put them in, in batch mode.
You will need to be registered here (free) to see and download the game packs in Downloads
