No, this is no April Fools joke! Following the preservation of arcade games Rockman EXE Battle Chip Stadium and Rockman EXE: The Medal Operation a few months ago, preservation group SciLab Secrets has now managed to get a hold of the final arcade game: Medal Network Rockman EXE.
Medal Network Rockman EXE was the first arcade Mega Man Battle Network game, having been released exclusively in Japan in 2002. Like The Medal Operation, you play the game by inserting arcade medals, which lets you roll dice and advance MegaMan on a game board, possibly netting you more medals.
Compared to The Medal Operation, the gameplay in Medal Network is fairly simplistic, though almost no information or footage about the game exists today. The team at SciLab Secrets is currently working on getting the game to a playable state; they are already able to boot into the game on MAME, though many of the graphics are corrupted. You can see some screenshots below.
