Save StatesĪ single save state is supported per ROM, which can be loaded/saved using the remappable keys mentioned in the Controls section. This is very cumbersome, however, so by default Player 2 is not mapped to any buttons. If you desire to play with a second controller, it can be mapped to other buttons on the calculator using the Remap Buttons option in Options->Controls. Note that if you set the turbo setting to 30 Hz, this may be too fast for some games causing them to malfunction. This is not re-configurable, and could very well lose your save data on games with battery backed saves. Volume Down - (minus), decreases the volume, though at lower levels it will have more scratchiness and lower accuracy.Volume Up: + (plus), increases the volume, though at the maximum level this will cause more distortion.

Help for the current selected option is in the upper right. You can also use ALPHA to quickly back out of a submenu. In the menu system use the arrow keys and SHIFT or ENTER to select. The emulator does support the NES 2.0 ROM format, but I haven't extensively tested it. Keep filenames for these files should be simple and less than 32 characters, such as MyGame.nes. NES roms (.nes) also should go inside of the root directory. InstallĬopy the nesizm.g3a file (or nesizm_cg10.g3a if you have an FX-CG10) to your Casio Prizm calculator's root path when linked via USB.

There is a large install base of players who can now play NES over many many hours of battery life with 0 input lag from keyboard to display. This project has its roots in my interest in early game development technology, as well as the inherent benefits of the Prizm as a platform. It runs most titles at 60 FPS with no overclocking on the FX-CG50.

NESizm was built from the ground up with performance in mind, while maintaining accurate emulation and compatibility wherever possible with clever caching, forced alignment, and hand written assembly where necessary. It currently supports the FX-CG10, FX-CG20, FX-CG50, and Graph 90+ E Casio calculators. NESizm is a Nintendo Entertainment System emulator for the Casio Prizm series of graphics calculators.
