ROG Ally Community Rebuilds The Proprietary Asus EGPU
As far as impressive hacks go, this one is more than enough for your daily quota. You might remember the ROG Ally, a Steam Deck-like x86 gaming console that’s graced our pages a couple lf times. Now, this is a big one – from the ROG Ally community, we get a fully open-source eGPU adapter for the ROG Ally, built by reverse-engineering the proprietary and overpriced eGPU sold by Asus.
We’ve seen this journey unfold over a year’s time, and the result is glorious – two different PCBs, one of them an upgraded drop-in replacement board for the original eGPU, and another designed to fit a common eGPU form-factor adapter. The connector on the ROG Ally is semi-proprietary, but its cable could be obtained as a repair part. From there, it was a matter of scrupulous pinout reverse-engineering, logic analyzer protocol captures, ACPI and BIOS decompiling, multiple PCB revisions and months of work – what we got is a masterpiece of community effort.
