I do playthroughs of old Cartoon Network games using mostly Flashpoint (these include games that are not originally from the CN website, though I decide on a case-by-case basis).
With the discontinuation of Shockwave and Flash, most of these games are no longer playable at their original sites, but BlueMaxima's Flashpoint allows you to play these games, provided they have been saved by the many contributors to the Flashpoint project. More details can be found in my video descriptions. I'm no longer in the Flashpoint Discord so if you have Flashpoint/game-related questions, please visit their Discord page.
I am only doing this as a hobby if or when I can, so don't expect me to answer all your requests. And no, please stop asking me whether I can upload the games' soundtracks or play non-CN games (I don't have any plans for those).
One more thing: The game "Teen Titans: Calling All Titans!" is played using Flashpoint Core. The loading issue has not been fixed yet as of version 11.
