The only thing it does is open a message box which says
Google Translator says it reads "please install"
- I guess I need the installer? Or do you have any registry keys of this game to share?
EDIT: It doesn't seem to look for any registry keys (checked with procmon by sysinternals) though it looks for a few files namely game.ini, install.dat, game.dat... Were any of these in your folder?
If I create install.dat blank (for testings) it says "insert disk..." in japanese, heh.
EDIT2: I guess you could say I'm a dumbass. It stopped mid extract (only 500mb in from the 716 mb of the exe) because the hdd was full
