Enebias: Ahoy there, GOGers! I know this is not a PC game, but... I have a code for Mighty Gunvolt, on the Nintendo 3DS, born as little reward for being a backer of Mighty No.9... too bad the damn racists at Nintendo decided that only North Americans can have it. So, if you are a North American, own a 3DS and do not loathe Nintendo's regional rescrictions like I do, the code is yours, no strings attached.
I cannot verify if it works, but I see no motive why it shouldn't. Just reply to this message to let me know if you're interested. More than a reply (though I doubt I'll get even one) will mean random selection.
I'm sorry I cannot offer this to anyone, but blame Nintendo for that. :(

lazylazyjoe: I'd like that, if you still have it.
