The Virtual Boy Japanese prototype "Niko-Chan Battle" is not a completed game. The homebrew community has in essence completed the coding of the game and has also done an English translation. If anyone is interested in having the "English" version of this game with it's own box art, then I found these custom boxes online. Sadly, I couldn't find the spine or the back, but apparently, you can actually buy these boxes from the creator from the interweb. Thought I would share that as it's really the only thing not included in the most recent Virtual Boy upload. There are translated English roms available called "Faceball Remastered" which is basically the same game as "Niko-Chan Battle" except the title/loading screen was edited to "Faceball Remastered". Maybe this box will get added in the future.
