it seems to be available with flashpoint. At least it is in their database but i haven't tried it.

Is it this?

It isn't detecting the microphone needed.

Yeah! Thanks!

(Edit: it doesn't use the microphone nor asks for it)

Awww, sorry. I didnt really tested it yesterday because it was late in the night.

Apparently the emulator they are using (ruffle) does not have mic support. I even tried the desktop version.
The only way I got it to work was using the adobe's standalone flash player. I use linux and installed the player from the software manager, but I found an archive on github that has executables for linux, windows and mac. I tested the windows version through WINE and that also seems to work fine.

You will need the direct link to the games swf file which is this:
https://enam.mariogames.be/mariogames/mariogames-1736/fosters-games-utter-nonsense.swf

You can either paste it directly on the flash player "open" dialogue or you can open it with your browser and it should download the file then open it with the player.

Hope you dont get any more trouble and Have fun! ^.^
