mktiupgrade 1.1.2

This update fixes support for explicit signatures and fixes support for Windows.

Windows users should download the included binaries. Mac users should compile it from source. Linux users can download the included binary but should probably just compile it from source. Cygwin users should compile it from source.

mktiupgrade 1.0.0

mktiupgrade creates (and optionally signs) OS upgrade files for TI calculators from ROM dumps. The first release includes support for:

• TI-73
• TI-83+
• TI-83+ Silver Edition
• TI-84+
• TI-84+ Silver Edition
• TI-84+ Color Silver Edition

In addition to supporting traditional OS signatures, it also includes support for specifying an arbituary signature, which may be useful to those hoping to exploit flaws in the TI boot code. It's built to be flexible and give you all the options you require to customize the build to your liking. It is suggested that you use other tools to produce a ROM file for your OS, which you can modify and feed into this tool.

If you are looking for a source of inspiration as to how you might integrate this tool into the toolchain for a third-party OS, try KnightOS.
