The manual for the 3DS VC version of Radar Mission contains a passage that went unnoticed either because people don't read manuals, no one bought Radar Mission, or both.
Radar Mission is the only game released on the North American 3DS VC so far that has multiplayer, so it is not entirely surprising that this news has not surface yet. But if this omission is generalized for all 3DS VC games, we can expect gamers to start caring a bit more once games like F1-Race, Waverace, or Pokémon, start appearing on the service.
Not surprised (given that no N64 games worked with Controller Pak functions on the Wii), but a bummer nonetheless. But still, the only game I would be seriously disappointed about with this would be Pokemon. I honestly don't remember playing any GB games other than that.
Yeah, I have to say I'm not too surprised, and honestly not too broken up about it. I kinda' expected that to be the case, especially since that would likely require at least some sort of basic recoding of the game and who knows how that would work (literally and legally).
Aside from one or two games not named Pokemon, I can't think of any GB games I played multiplayer and took seriously. I actually played more Lynx games multiplayer, lol...
...wait, that's not funny, that's kinda' depressing.
Disappointing news. Not unexpected though. But honestly, I rarely played multiplayer games on Gameboy, so I suppose this won't affect me personally. Tetris on Gameboy is the only one that I really got a lot of use out of on Gameboy, not counting Pokémon. Of course, both of those franchises have updated versions that blow the old ones out of the water, so... yeah. No harm, no foul from my perspective.
