Custom Firmware for ATGames Legends Flashback

Was wondering if there is any progress for making it possible to add games easily or replace the firmware? The only mentions that I have heard is that you would need to desolder the flash chip, place it into a programmer, flash the games you want, and then solder it back in. The process is very time consuming, and overtime, the pads would start to deteriorate. Looking for answers here.

Reviving this thread real quick to give anybody some clues on what the hardware is. It uses a Monkey King 3B SoC, which is supposedly an AllWinner A13 or some other chip, since most of these from DMC are mostly based on AllWinner.

I think all Legends and Genesis Flashback devices from 2018 to 2020 used same rock monkey chip. I'm guessing Pico can be installed. There's no sd card so hence de solder chip.

How can a Pico be installed into these?

This device is not based in Rockchip (Monkey King 3.6/RK3036 and RK3066) or Allwinner SoC, it uses a custom chip like the one running on the Atgames Atari Flashback Portable. I don't think anyone was able to access this SoC besides using a reader to extract the Flash Memory contents.

Be sweet to add screen and battery to unit and replace board with Legends Flashback 2018 50game board to this unit or maybe put in Ambernic Sega unit. I simply cannot play anything without rewind feature anymore lol.
