An artist and retro gamer who goes by the name PlatinumFungi created a fully functioning, Mega Man-styled NES mod entirely by hand, according to a post on his site.
PlatinumFungi tackled the project in honor of Mega Man's 25th anniversary. The mod was created by "cutting, filing, sanding, wiring [and] soldering," PlatinumFungi wrote, and everything created with hand tools.
"No professional cutting, etching, or other machines were used," PlatinumFungi wrote. "I lost track of how many hours went into this weeks ago — it was truly a labor of love."
