NES emulator for Windows Vista/7 has been updated. Changes:
- Sound engine improvements - audible adjustments to playback frequency are essentially eliminated;
- Fixed IRQ behavior following CLI, PLP, and RTI instructions (fixes Pinbot, High Speed, and some test ROMs);
- More accurate MMC3 implementation;
- Fixed sprite DMA from non-CPU memory (fixes Noah's Ark);
- CRC-based detection for ROMs that aren't adequately described by iNES headers
ROMs are cached on startup for smoother scrolling through the menu (can be disabled in nemulator.ini);
- Hotkeys for resetting games (F2) and switching between fast and accurate emulation modes (F3);
- Emulation of emphasis bits and grayscale mode;
- Fixed handling of OAM reads via $2004 while rendering; Micro Machines is working properly now;
- A lot of code reorg/cleanup and a few bug fixes.
- Added support for the following mappers: MMC6 - Startropics, 23 - Contra (J), Parodius, Crisis Force, 67 - Fantasy Zone 2 (J), 78 - Holy Diver (J), 93 - Fantasy Zone (J), 94 - Senjou no Ookami, 119 - Pinbot, High Speed, 184 - Atlantis no Nazo, 185 - Spy vs. Spy (J), Mighty Bomb Jack (J).
