If you already have it and it doesnt run then either you lack the runtimes required or you havent changed the region to japanese
You need to have the following installed to run any game on windows 8 or up
.- directplay
.- directx jun 2010 (this is used always and there is no excuse like i have directx 11 why i would have to install something like that but is used in every game)
.- visual c++ from 2005 to 2013
.- Run all the games as admin
Those are the minimum to run a game.
The game you are using is kinda messy for a newby specially in the crack part but there are only 2 possibilities :
.- First crack the game with the DVD in place (you need to burn a copy on disc otherwise it wont work) and run it.
.- After the game has loaded you remove the disc and close the game,after that run the game again without the disc it should load normally without disc
.- If it doesnt work the game has a special security measure but with the crack the game would load normally with the burned disc in place.
There is no need for the x64 version of the crack (I think there is none because all the games in japan are 32 bit) so grab the normal 32 bit it doesnt matter if you have windows 64 bit or not,
