1G1R Lab started the way most retro projects do: a new handheld, a fresh SD card, and a weekend that turned into a year. Duplicate ROMsets, region variants, broken conversions, mystery folder layouts, firmware quirks — every problem solved twice because nothing was written down.
So we wrote it down. Twelve months of research, 59,000+ games curated across 96 systems, battle-tested on 3 real devices. The lab exists so your build takes days, not months — with tools that are honest about what they do, run entirely on your machine, and never touch a file without your approval.
This boundary is permanent and non-negotiable. It is what allows the lab to exist in the open.
