Because Adobe Flash got shut down, the game can't be played anymore. The only two ways to bring it back would be if either a version on a different emulator would be made or the game gets turned into an exe.

Download Flashpoint to play DSYP (currently the only way to play it).

Yes, I posted about it in the Resources tab

Just use Adobe Flash Player Projector, it's from adobe and it runs games natively without emulation
