A nice way to start it from the menu is to make a new .sh file for it, so you can decide if you like starting it with cheats or without. Simply make an new "prince_with_cheats.sh" file in the folder /home/pi/RetroPie/roms/ports and let it change the directory to: /opt/retropie/ports/sdlpop before starting the game with "./prince megahit". Troubleshooting / Tweaking / Saving the game: You can change the in-game behavior of this game in the following way: Go to the folder: /opt/retropie/configs/ports/sdlpop There should be an file called "SDLPoP.ini". If not, copy the file SDLPoP.ini.def over it. When you open this file you can edit some of the configurations of the game, like from which level onward you are allowed to save the game (default = 3). There are many other tweaks possible, the file will explain itself.
