Coremaze undertakes a reverse engineering journey to revive the USB interface of the ME2 handheld device, a 2008 toy that synced game data with online worlds. When no software or drivers survived for this niche device, the preservationist from Miuchiz Reborn community had to physically extract the firmware chip to uncover its communication secrets.

With no archived software to reverse engineer, the author turned to hardware extraction. After failing to desolder the SST39VF3201 flash chip with conventional tools, they used a heat gun and knife to remove the protective epoxy blob covering the microcontroller. This revealed the silicon die underneath but no identifying markings.

The dumped firmware contained USB communication code, but identifying the instruction set proved challenging. Despite trying various processor types in Ghidra disassembler, the code remained undecipherable. Even after finding USB-related signatures in the code, the mystery persists without a clear path forward.
