Hypnotic School Life : Sexy and Nude, The Imperial Gatekeeper, Goblins Burrow, Lazy Angel Mika, and License to Breed are not RPG maker games.

RPG maker games have a blue tag with the text "RPGM" on it.

For the last game, The Black Guards of Odom - Desert Town Prison, it has some very windows specific plugins which aren't compatible with the launcher.

I am working a tool that will work with the other games but it's far from ready and still very much in beta:

Hi! I can't believe I just stumbled onto this. Does it work for Mojave? I tried opening it and absolutely nothing happens!

It should work for Mojave, did you do it with this (different versions of macos have different ways):


If it still doesn't work, try looking in:
~/Library/Application Support/RPGM-Launcher/log.txt

and post the contents of log.txt here


And if the logfile isn't there, try opening up the terminal and run the following (assuming the launcher is in your downloads folder):

cd Downloads
open RPG-Maker-Launcher.app

and post the output here

which game are you trying to play.

The launcher isn't able to find some required files within the folder you've selected. It's possible that the game has been packaged in a way that hides the assets.
