For all those missing their old .swf format games there is the stand alone offline flash called projector'.

Have fun and remember to download and preserve.

Just gonna np this to get it back on the day list for people who haven't seen and might be interested.

There's an open source one out there, too, but i can't remember the name of it.

I just think it's nice to have a more native solution than trying to get old software that won't be updated to look where you want it to for files it may not recognize.

those were so bad games
glad they went to mobiles

not really some of the best shit was on adult swim games; wish I had gotten them while they were available.
I mean 'cream wolf' need I say more?

Then take a look at
https://bluemaxima.org/flashpoint/
CreamWolf is there as other AdultSwimGames together with 80000 games

Yeah, Flashpoint is THE definitive final stop when it comes to Flash stuff. If it ran on Flash, they most likely have it.

You can either download everything at once or browse games through their program and download on demand (to save space).
