Nofrendo
Nofrendo is a NES emulator. Do you want to play your original Mario cartridge on your NumWorks calculator? Search no more! Thanks to this emulator, you’ll also be able to revive many other classic games like Super Mario Bros 3, The Legend of Zelda, Metroid or Castlevania!
How to get games
We can't provide you any games, because of legal reasons. However, you can download games from the internet easily. A search like "nes roms" should give you plenty of results. You can also dump your own cartridges.
You will need to add your rom as an external file. To do so, follow the instructions in the how to install guide.
How to play
The controls are rather straightforward, because the NumWorks calculator uses a layout that’s very similar to the NES gamepad. Select and start are less obvious, so here’s a recap:
| NES gamepad | NumWorks |
|---|---|
| Arrow keys | Arrow keys |
| A | Back |
| B | OK |
| Select | Shift |
| Start | Backspace |
| Reset | Tangent |
| Save state | Square root |
| Save state and exit | 0 |
