I already answered. I have "installed" swf files on my n800 (one was "Bloxorz" (a game) and another was a stopwatch program. Both were simply .swf files and I put them in a directory and created a shortcut to run each. The weren't "Popcap" games, but they were swf files.
Popcap swf-files are protected so you can't just copy the swf-file. I did little script what maximizes the flash-object: http://laasonen.net/popcap.user.js What you have to do: 1. Install greasemonkey-webaddon. 2. Go to this address and click yes. 3. Go to the game with your browser, for example here. 4. Click the +-button and add shortcut to desktop. Now you can start popcap-games from desktop and play them on fullscreen EDIT: I didn't notice that all of their games don't use the same technic, so it wont work to all of them
