[Lovable Chevy] finished her portable build, ending up with a handheld that takes both SNES and NES cartridges. We’ve got to say congratulations on reaching the finish line as her first build log post was in March of ’08. But it was worth the wait. The little device, which is a mash-up of the hardware from a Retro Duo along with a PSone screen and 4250 mAh battery, looks quite nice thanks to her skill and patience when building the case. Take a look at the obligatory demo video after the break.
