there is no need to put anything in path, run the game from command line:
cd <poom folder> ./poom_1.9
Don't lose too much hair over me, haha! :D I've got the standalone, but it does the same thing - that is to say, I don't know what to type in and do for Ubuntu for doing this:
mkdir poom <path to pico>\pico.exe -home . cd poom\carts REM change xx to actual version number unzip poom_standalone.xx.zip
When I right-click the "poom_1.9" file in the "poom_1.9_linux" folder, and select "Run", it doesn't do anything. When I do ./poom_1.9 in the command line it gives the error: "error while loading shared libraries: libSDL2-2.0.so.0: cannot open shared object file: No such file or directory"
