The Cartridge PiRTO II DUO made by Aotta is the new version of the PiRTO II multicart for Mattel Intellivision based now on a Raspberry Pi Pico2 for using double RAM.

This version support Intellivision bin+cfg games, including the JLP acceleration and savegames features.

Here are some improvements that i have made to the PiRTO-II Duo cartridge cover:

• Reduced the hole for inserting the Mini SD Card. (Unless you have fingers big as sausages, you can easily remove and insert the Mini SD Card. I’ve seen much worse situations)
• Added new PCB support bracket. (When inserting the Mini SD Card, the PCB flexed downward)
• Added hole for the Raspberry Pi Pico2 button. (Useful for updating the PiRTO-II Duo without opening the cartridge)
• Added hole for the USB connector. (Useful for updating the PiRTO-II Duo without opening the cartridge)
• Increased thickness of the front/top internal cartridge support.
• Slightly narrowed the hole for resetting/restarting the cartridge to use the button cover.
