For those who like the details:


- The logo_24xx.bin is a GIR file of type 19 (like the 37xx).
- The logo inside is a 16-bit bitmap encoded in 565 color (as opposed to a PNG in the 37xx)
- The original file logo_24xx.bin is way too big. It has been made as a dump of a 24xx flash memory. It is filled by unused FF at the end of the file. GIR_Editor will remove them which will explain the smaller file size.

GIR_Editor v0.40

This program will extract all symbols from a fw1_resources.bin file or logo.bin file. Such files can be extracted from .RGN or .GCD firmware files using RGN_Tool. Symbols can be extracted, previewed and saved from fw1_resources.bin files. So far, only resource files with type 10, 11, 12, 19 or 20 can be opened. The program will tell you if the file type is not recognized. If you have a GIR file of type 19 & 20, you can also replace existing symbols by new ones of any file size. Once modified, save to a new resources.bin file and flash to the GPS. (Refer to previous post above this one for examples of what can be done...)

When logo.bin files are used, symbols can be extracted, previewed, saved and replaced with new bitmaps bitmaps of the same dimentions, but with different file size. Symbols are converted and saved as 24-bit bitmaps. You may edit and save the bitmaps with different editors including MS Paint. You may save the new symbols as 16-bit RGB 565, 24-bit or 32-bit bitmaps. When replaced, they will be converted back to 16-bit RGB 565. No compression is involved so do not worry about file size if you use the same bitmap dimentions. Once done, you can save the moddified file to a new .bin logo file.
