Some features are disabled in the Nspire versions: the key combo for the self-test doesn't work, and the TI-84 Plus Silver Edition OS can't be upgraded (an error is returned by the computer link software). The version of the boot code is 1.02, according to 0x400F of ROM page 7F (see WikiTI). Starting with version 2.42 (and continued with 2.44 and 2.46), even-numbered versions of the TI-84 Plus Silver Edition OS are used while the latest version available for the real TI-84 Plus Silver Edition is 2.43.
The speed is roughly the same, and the RAM and archive memory have equivalent sizes (the whole memory of the TI-Nspire is not visible from the emulated TI-84 Plus Silver Edition). Fortunately a ROM image of the emulated TI-84 Plus can be dumped through the DBUS with standard tools such as TiLP.ĭo not expect the emulated TI-84 Plus Silver Edition to offer more features than the real one. The OS code is encrypted and perhaps compressed with the rest of the TI-Nspire OS code in certificate field 8070. The archive memory of the TI-84 Plus Silver Edition is integrated to the TI-Nspire OS as 64KB files in a PK-Zip file (see the OS upgrade file format).
