# How to play
It’s quite obvious, given how the NumWorks’ keypad looks just like a Game Boy’s. Anyway, here’s a list of the bindings between the NumWorks’ keypad and the Game Boy’s:
| Game Boy | NumWorks |
|---|---|
| Arrow keys | Arrow keys |
| A | Back |
| B | OK |
| Select | Shift |
| Start | Backspace |
To modify the behavior of the emulator, you can use theses keys:
| Key | Action |
|---|---|
| 1 | Use the original game boy palette |
| 2 | Use a pure greyscale palette |
| 3 | Use an inverted greyscale palette |
| + | Render the screen in fullscreen |
| - | Render the screen with the original aspect ratio |

WARNING
Peanut-GB (Color) require more RAM and use more CPU time, so some games won't work at all or will not work in realtime (e.g. 2 second in the real world will last 1 second in the game). Most Gameboy Color games can run on normal Peanut-GB in greyscale for better performance.
