Change the amount of memory the game should allocate when loading game data

Unlicke more modern games, Disa doesn't allocate its memory dynamiclly based on the game file. Instead it has a fixed size buffer which is created when the game is started. If you mod the game with files which exceed the size of that buffer, then the game will just crashes. The Disa PC File Manager contains a utility that allows you to modify the size of the buffer to accommodate bigger file sizes. (Thx to Kelebek1 for finding the memory location)
