So yesterday, I noticed something happening that never happened to me before. If you play any game on the plugin, you will see the yellow link on the top left of your screen that says "Play using Mednafen". Now, when you click on that link to use the Mednafen emulator, everything goes to a white screen that says "This game is not playable". I have tried this for numerous games for different systems, and it happens everywhere. They only way that you can actually use the Mednafen emulator successfully is when the game's page has Mednafen as one of the options for emulators to choose from in the PLAY NOW links. But not many games have this on their pages.
I then noticed that there is the 2.3 plugin available and hoped updating would fix this. It did not.

Davideo7 : I know that you get PMs and summons to plugin questions a lot and we are typically supposed to go through staff first, but this is something I have never had happen in the years I have used the plugin, so I thought you would want to know. Without being able to switch to Mednafen, those new features you had put on such as the recording, playback, rewind, etc are no longer possible to use.

I just fixed this issue a few hours ago after some users reported it to the latest 2.30 thread. Please let me know if you're still having any problems.

Davideo7 : Just tried it on a few games. Everything seems to back to normal. Thanks for the quick response.
