Hi,
i've just published my last DIY project for a Flash multicart based on raspberry "purple" Pi Pico clone.
It's a simple and cheap project, i hope you'll like it!

here's the link:

Great job!

Oh wow, that's really cool!

A friend and I had a question regarding this statement:

WARNING! "purple" Pico has not the same pinout of original Raspberry "green" ones, you MUST use the clone or you may damage your hardware.

Can you clarify exactly what this means?[/quote]

If you look for "rp2040 board" or "pico purple" on aliexpress you'll find several offers with different options: green ("original"), black or purple.
The differences are not limited to the pcb colors, since the black has 4mb flash ram instead of the "standard" 2mb, and the purple clone has 16mb flash ram. The not green boards also have a usb-c connector instead of the older used by Raspberry and, most important, they exposed more gpio/pins for using in projects than the green. Only a couple, but really useful when you need 16 GPIO handling bus and 8 GPIO for data! ;)
But, for having more pins with exposed GPIO, the black and purple board had to change a little the pinout, removing some GND pins and CHANGING THE PINOUT FROM THE ORIGINAL RASPBERRY PI PICO (you can note it on the attached pictures).

So, in my SD-1000 i used the "purple" one.
I'm pretty sure you could use also the "black" one (but i haven't tested it) for a multicart with only 4mb for storing games, but you CAN'T use the original PICO since it doesn't work and could be damage itself or your SEGA if used!
