User Guide - dkidd928/cartreader GitHub Wiki

The Cart Reader shield for the Arduino Mega features SNES, Megadrive, N64 and GBA/GBC slots all on one pcb.

SD Card

The sd card should be formatted to Fat32 and be reasonably fast, I'm using a 4GB SanDisk SDHC Class2 SD card. You also have to copy the files from https://github.com/sanni/cartreader/tree/master/sd to the root of the sd card.

Configuration Switches

The little arrow printed on the pcb itself shows the direction the switch needs to be set to be enabled.
By default all switches should be disabled and only enabled if explicitly instructed to do so.
