Thanks for the tips! One caveat I should have added is that I'm talking about one switch purely from the physical access point of view. Adding cognitive disability issues (the area I work in) brings up a whole different set of design challenges.

For picking letters/numbers/menu-options, many of the games I've seen use a timed rotating selector. This could be a pointer rotating around a dial, a highlight skimming from top-to-bottom (or left-to-right), etc...once the highlight/pointer is over the desired item, the button-press chooses. It may also be good to include a cancel/back option and an "I'm done"/okay button with longer dwells (and for text-entry, a backspace). One of the other things I've liked with the rotating-highlight in a menu is having it actually slide over the blanks-between-options too so that there's a bit of space between them to assist you in choosing the option you want, rather than being off by a fraction of a second.
