r83: port over some patches from Japanese guys. supposed to fix touhou games.

from their notes:
- Bug fix. When you save a state data in same slot after you save one, hourglass is crashed.
- Save state data in file.
- Change initial value of non-deterministic timer.
It saves state datas in local file.
As a result, it uses less memory than original one.
The state datas are saved in the same folder as the hourglass.exe.
