Ah, right x.x. Is there a way to fix LCD issues on a regular 83+?

No way AFAIK except to modify the program, a near-impossible task without source code. :(

How common is it for an 83+ to have a slower LCD driver, anyway?

It's guaranteed for pre-2003 calculators. The pre-1999 83+ Series uses the Toshiba T6A04. In 1999, it was switched to the equivalent Toshiba T6A04A. After 2003, TI-switched to the Toshiba T6K04 for the 83+, 83+ SE and the 84+ series. I'm not sure about the 84+ SE, though. Interestingly enough, all of those drivers can handle screens at least 120 pixels across and 64 pixels high.

Not very. I mostly heard about those issues back when the 84+ came out. Some 83+ users had LCD problems but then a few years later I heard less about those problems on the 83+.

There's some really interesting stuff that can be done with this.

Look at Z-Address and Word Size to see some really cool stuff! ;D

Yeah I believe Z-Address is what ROL2 and some of my other old RPGs use for earthquake effects
