NES emulator for Windows has been updated recently. Changes:
Major Bug / Crash Bug Fixes
*Fixed throttling problems that resulted on AMD Dualcore processors. (Caused FCEUX to appear to be in turbo mode).
*Fix major crash issue where NROM game (such as SMB) savestates were writing erroneous information if a non NROM game was loaded prior.
*Fixed a bug that caused a new sav file to not get created when loading a 2nd battery backed game.
*Fix Directory Overrides so to allow users to have no override. Also fixes directory override reset bug.
