Title Ultimate PTT Patch
Description The second version of my ptt patch. It erases the evil part of the Push-to-Test code from the TI-84 Plus OS. Afterwards it only displays an option screen and a fake "reset complete". Hooks are preserved, groups and pics too, and programs remain undisabled. OS version 2.43 only. Changelog: - FlashDrv is not needed anymore - Version check for fool-proofness

Note! This review was written for a previous version of this file!

For those who don't follow events in the TI-sphere closely, the PTT function is a new feature in the 2.40 and above TI 84 OS. If you hold down the left, right and ON keys at once while the calc is off, you will get a menu that allows you to enter testing mode (go ahead, try it). If you turn the mode on, all your programs and apps are disabled. Needless to say, this feature was designed for teachers to limit their students' calcs.

As for the program, it disables this feature. It works, and that's the most important part. After I hacked my calc using the program, I got a fake PTT reset menu instead of a real one. However, few teachers are tech-savvy enough to know about PTT in the first place, so the program is of limited use. Hats off to the programmer, though, for digging into the system OS and finding a "patch."
