Instructions | A custom DS flashable cartridge

1

Compile & encrypt the ROM

Compile and encrypt the ROM for the cartridge following the compiling information in this repo.
2
Compile the RP2040 firmware
Compile the firmware with your ROM following the guide here.
IMPORTANT: The DSpico has a function to automatically reset if the microSD card isn't inserted when powered on. This behavior can be disabled by commenting this line present on main.cpp:
```
initSd();

// tryRebootToBootsel(); <-- Comment this

pwr_initPowerSaving();
```
3

Fabricate the Flashcart

Grab the files present in GerardGascon/fanzine-ds-hardware and export all the fabrication files from there.
If you are using JLCPCB for the production, they have a guide here + a plugin that easily generates those files for you.
ADVISE: If you want to test the software before fabricating the hardware, you can do so by just using an existing DSpico and later on fabricate the flashcart.
