I'm more than willing to both playtest and/or code, but I don't know if I really have enough credentials for either...
for playtesting: I'm no scrub, but I'm no pro either. I've only been to a few local unofficial tournaments (like one at my house in high school for melee (50 people... most of the people there were scrubs though), a Brawl one at GameStop the opening night, a few hosted by a gaming club at UWEC)... all of them I got either 1st or 2nd. None of that says much imo, but I have improved significantly since then... in Minus I mostly focus on Peach, Snake, DK, and Diddy and I'd be more than willing to narrow down to one character if you want testing on any particular character (I play almost every character... the ones I listed are just the ones I play / like the most.... DK is by far my best). As for how often I can playtest against (good) human players... pretty much every day for an hour. On weekends more. Both my housemates play smash and one of them is of similar skill level to me (we do one on one and take turns) and the other is not far behind (he didn't play smash much before but he's getting good fast). I could see if I could get some of my other friends to play me more (who are also solid players), in which case I could playtest even more.
as for coding: I have no idea if I'm presently capable of it... I'm a CS major at EC, but that's a recent change, and as such, I'm only in sophomore level CS classes atm. I've never done coding for smash, so I don't know how hard it is or what exactly it entails... I can tell you that I know Java best and have some experience in C++. If someone's willing to get me started, or at least send me a link to a tutorial or something, I could see if I'm capable of it. If I am, I'm more than willing to spend about 5-10 hours a week on it (I don't know if I could afford much more with the exception of when I'm on break... I'm taking a three CS classes that are supposed to be taken in sequence, all at once this semester, so that eats up a LOT of my time).
so yeah... that's that. Really not sure that cuts it, but thougth I'd offer. I'm certainly interested.
