Another handheld continuing the lineage of “homebrew” devices, although certainly a bit closer to the “emulation handheld” style of systems. Releasing sometime during 2013 after a successful Kickstarter campaign, the GCW Zero doesn't seem to have sold a lot, but it was received relatively well anyway. Specification-wise, the GCW Zero contains 16 GB of internal storage, a 1GHz Ingenic-brand MIPS CPU, a 320×240 screen, and 512 MB of DDR2 RAM. Some imply that at least a few proper games released for this device, which means it cannot be merely considered an “emulation handheld”.
