I'm trying to build an arcade cabinet from scratch (not totally from scratch, since I would probably get the cabinet wood parts done by someone else) and, as all the noobs, I have some questions i would like to ask:
-This whole thing about keyboard encoders has confused me pretty much, and so i ask a simple question: how many buttons will I be able to push simultaneously without any problems, and does this vary from encoder to encoder?
-I want to build a cabinet for 2 players, 7 buttons each, a trackball, spinner, etc. I would love it if you had recommendations for the joysticks(8-way), buttons(would like microswitches), and the trackball.
Sorry if I've made you mad with my noobish questions

, but bear in mind that I'm only 14 yrs old and got a lot of questions (should be ordering Project Arcade soon to demystify some stuff

)
More questions will probably follow, since i'm a little tired now (going to take a nap)
