Save yourself the frustration! |
The fact is when you can buy a mini-pac for less than $30 (plus shipping) or for about $5 more get a similar controller from Groovy Game Gear, spending hours first learning about things like matixing, ghosting, and blacking and then actually taking apart and figuring out how to hack your keyboard is just a waste of time.
Sure, ten years ago, it was a great option, but thanks to Andy and Randy (the owners of Ultimarc and Groovy Game Gear) it's just not worth the effort. Now, if you are a masochist there are several good webpages devoted to hacking keyboards (1, 2), but you will not find me wasting either of our valuable time discussing it.
