Just put the .rvdata2 file into the main folder, which also has the game.exe.
If the game had been made with RPG Maker MV (has a www folder or is only a "game.exe" for example, if it's still compressed), then put the file into www>save.
in my game i see that i have 999 arrows and 999 potions, and i run through all the map and find only zombies, nothing else! i cant get into any house or meet anyone. Pls help.
