@rpimagazine It's scary how versatile these Pico's are. I've now got Mega CD emulation running on my RP2350B flashcart: https://t.co/mhtL8sVIyN

@GOROman If you're level shifting you can then multiplex the lines, reduce pin count requirements, which opens makes cheaper microcontrollers an option...

@rpimagazine Now have 2x RP2040 flash carts soldered up for the Sega Game Gear.

Another option to update Pico's is to create a TinyUSB MSC device that acts like a usb flash drive, use "FatFS" (or similar) to create a volume on some spare flash storage. Check if .uf2 file was copied and write the update to flash with your own firmware. No bootsel mode needed.
But depends how large your firmware is likely to be as u need extra space to hold the copy before applying the update.
Anything goes wrong, always got bootsel mode to fallback on.

@HD64180 Happens to me quite often, the Picos I'm using have reset button (to short the reset pin) and then will connect properly.
I think after some uses the usb starts to degrade and this connection problem starts. The baud rate trick sounds similar to resetting it.

@i2cjak Did u say Doom on an esp32?

Updated Game Gear flash cart PCBs. First one soldered and confirmed working. Longer duration playtest next.

Features include:
- Slot 0/1/2 4MB bank switching
- SRAM save games
- USB access to SD Card
- 10MB onboard flash drive (i.e. for if/when you don't have an SD card)
- ROM menu with themes and boxart/screenshot browsing

Here's how the boxart/screenshot browsing currently looks:

Pico GG Cart is an RP2040 based flashcart for the Sega Game Gear... if it wasn't obvious.
Here's what the current *prototype* looks like:
