I never thought that I’d ever have to say this about a prototype, but this Daikatana Game Boy Color development cartridge, which came directly from DOOM designer John Romero, has too many differences. Documenting them all was a colossal challenge that involved taking nearly 2,000 comparison screenshots over a period of months.

Leave behind any prejudices that you may have about the PC first-person shooter because, as an old-school-Zelda-inspired throwback, the handheld Daikatana‘s right on point.
