nemulator 2.1
* nemulator now includes a cycle-accurate emulation mode! This mode enables accurate emulation of games like Battletoads and Marble Madness and eliminates graphical glitches in many other games. The scanline-based (fast) mode is used in the menu, and the cycle-based (accurate) mode is used in-game. This is configurable in nemulator.ini.
* Added options to disable sprite limiting (to reduce flicker) and to mask the sides of the screen (to hide scrolling glitches). These are configurable globally and on a per-game basis; see nemulator.ini.
* Fixed bug that could cause random hangs on game selection.
* Improved audio resampling.
