Something's wrong with this crack. I've only gotten this game to work by using the crack on the "g5.exe" file that's on the iso. Installing the game and trying the crack afterwards only results in the game opening then immediately crashing. Please post a step by step guide on how to install and play these games?
EDIT: got it to work. Here's what I did:
1 - Switch local to Japanese, restart PC.
2 - Load the ISO. Changed the install.exe within the ISO to windows XP compatibility mode (I'm using windows 10).
3 - Did the full installation, then used the crack on the game's .exe file.
Note: it only opens if I use the crack to open it, but I can save the game and it's working. So. Yay.
