I have tested it on the following calculators that I own:

TI-83 Plus (OS v1.19)
TI-83 Plus Silver Edition (OS v1.19)
TI-84 Plus Silver Edition (OS v2.55MP)
TI-Nspire with TI-84 Plus Keypad (OS v2.46)

Community members have verified that it works on the following variants:

TI-84 Plus
TI-84 Plus Pocket SE
TI-84 Pocket.fr (French version of the Pocket SE?)

The following calculators are not supported because their internal hardware and firmware are too different:

TI-73, 80, 81, 82, 85, 86
TI-83 (without Plus)
TI-84 Plus C Silver Edition
TI-84 Plus CE
TI-83 Premium CE (French version of the TI-84 Plus CE)
TI-Nspire CAS, CX, CX CAS, CX II, CX II CAS
TI-89, 89 Titanium, 92, 92 Plus, Voyage 200
