If you want something a little more badass looking, I might take a request for a Keystick.
It doesn't have the same close feel as an actual keyboard, but it's pretty usable. No messy configuration either.
I know I posted this before somewhere, but here is the picture:
This box came out pretty bad but I'd make you a far better looking one (this was a gift so I wasn't going to make anything professional looking, though money would certainly motivate me otherwise). The art I think was fine though. The ironic part is the start and select button are sanwa's (The Japanese standard for Arcade-stick high quality buttons).
The keys I use are mechanical, so it's pretty highquality. Way better than your plastic sensors in most keyboards.
That being said, I highly recommend you just learn stick. Very few people these days (except maybe Chibi) "learned stick" just because they played in arcade. They made the choice to set back their execution for a couple months to learn it, and it wasn't easy to start. But if you
really want it I can be paid to do it because I'm lacking money these days. PM me if that's the case. What's also been done is people like "arcade buttons" but not the stick itself. So they just get all arcade buttons, including a PC-Style setup 4 arcade buttons (generally sanwa). Just so it's organized/looks like a keyboard, but are big arcade buttons. I can do that as well, if it sounds more appealing. If both you and Shadow want one, it'd definitely be easier me to bulk order parts. I could also do different layouts, if you would prefer that as well.
The standard would be PS2/PC compatible (though lol if it's PC compatible why not just use your keyboard). I could look into the possibility of doing other systems as well, though.
