Re: Magician of the Olecta Desert
Okay, can you attach the screenshot and tell me when exactly the error occurs? It will be much easier to narrow down the issue between something internal to the game and requiring an updated patch versus some incompatibility with your system.
Assuming it isn't an internal problem, here are some random thoughts for a solution, apologies if you've tried these already or they seem obvious:
Make sure that you've actually changed your locale to Japanese. Depending on your version of windows, there may be a bunch of different places where you can change a region setting. What you're looking for will be described as "Language for non-Unicode programs" and will likely require a restart.
Try opening the game.ini file and changing the line that reads Library=System\RGSS300.dll to Library=System\RGSS301.dll (or vice versa). Make sure that the .dll file you're switching to is in the system folder; rgss301 should have come with the game and I included rgss300 in the patch.
Really reaching now, but... try placing the game folder somewhere else or running in a compatibility mode? Check that you have the VX Ace RTP installed (it's not the same as the VX one)? Witchcraft?
