What are 92I files and how to open them

Are you having problems opening a 92I file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your 92I files.

What is a 92I file?

A .92I file is a TI Bitmap file.

TI Bitmap is an image file created by Texas Instruments devices, specifically TI-92 graphing calculators or the Graph Link software, used to store simple monochrome pictures taken or drawn on the calculator. A PIC variable of the TI-92 can be copied or transferred via TI-Graph Link or similar tools, saving it in a file with the .92i extension. These picture files are typically used for adding graphics, backgrounds, or custom images in TI-92 projects or display routines.

TI Bitmap files are produced by storing PIC variables from the calculator's memory. When transferred to a computer, the file format encodes the picture data along with a header that allows linking software to identify the variable type. Software that interacts with TI-92 variables - TI Graph Link, third-party tools such as TiLP, or utilities in the TI development community - reads .92i files, typically for preview, conversion, or re-uploading back to a calculator.

TI Bitmap files begin with a distinctive 8-byte ASCII signature TI92 (bytes 2A 2A 54 49 39 32 2A 2A) at offset 0, followed by a standard TI-variable file header. The image part ('PIC' type) contains a 2-byte "data length" field, then 2-byte height, then 2-byte width, followed by row-packed 1-bit-per-pixel bitmap data (each byte holds up to 8 pixels). After the bitmap data comes a tag byte that always has the value DFh.
