Lol meow. I've never ever changed my nick to Sev|PSO. But since you asked the other day, i will do that hence on, for you.
To clarify it: Yes, for some reason you get the map_data error message if you don't start from one of the executables in the folder. I also noticed the game adds shortcuts and yet an executable file when you launch it.

Removing this did not give a satisfying result.
Anyone playing this with a controller pad? Obviously SEGA didn't even bother remaking the controls in their port of the game, and it's still making me go crazy.

HOT!!!!
tenkei: meow never told me the game don't save its own screenshot but you just take a print screen. So all the pics I took that day are long lost.

Remember that people. If you take a screenshot, make sure you paste it in your favorite image editor (my case mspaint) before taking another. lol.
