Editing TI-89 Program with .89z Extension? - Cemetech | Forum | TI-BASIC [Topic]

Hey Guys....i got a ti program from a friend of mine with file extension 89z. i want to edit it but i can`t open it.Any help?

From what I've been able to gather, it's an assembly program format. Looking at http://www.ticalc.org/archives/files/fileinfo/410/41007.html , the .89z is the program that runs the game, the .89y are support files holding data. If memory serves.

To extend that further, if as tifreak8x says it is an Assembly program, then you won't be able to edit it unless you have the source code and a compiler or assembler. This contrasts with a .89p program, which is TI-BASIC and can be modified on-calculator.

yes it`s an assembly program but i dont have the source code...i tried with a lot of programs to edit it but no success

Using a program like IDA Pro (or other m68000 assembly decompilers), you could get the assembly source from the .89z (once the actual executable data is extracted from the .89z), can be edited, reassembled, and put into a .89z.

This, however, is an advanced topic requiring disassembling and m68k experience.

AFAIK, IDA Pro doesn't have features tailored to TI-68k/AMS ASM programs. dasm-tigcc ( https://github.com/debrouxl/gcc4ti/tree/next/trunk/external/dasm-tigcc ) and obviously TIEmu do.

One more question.I am more familial with c++ and i wonder if there is a program which can change a c program to ti program.Is it possible?

Yes, the suite GCC4TI lets you compile C programs for the TI-89 series of calculators. Unfortunately, there is no such widely-accepted equivalent for the TI-83/TI-84 Plus series.
