There is a web version of Flashpoint called 9o3o on https://ooooooooo.ooo/browse. If you click a game and then open your browser devtools and search for "data-game-zip", you will find the link to the game files in that attribute. Download and extract it and go to town.

Some games won't work if you try to play them outside of Flashpoint though: https://flashpointarchive.org/datahub/How_Flashpoint_Works
