Bitmap Hunter V4







Hi Guys,
Bitmap Hunter is a homebrew program for Sony PSP designed to hunt,
and directly edit monochrome or 256 colour bitmaps within firmware files for electronic devices
so they can be user customised.

This one was inspired by HACKBMAP.EXE by Datrex, a DOS application
used to hunt for bitmaps within Garmin Etrex GPS firmware files.

Hackbmp.exe did not have the functionality to edit images,
so it was only good for finding bitmap offsets to be later edited with other tools.

Screenshots provided show samples from Garmin GPSmap 60CSx GPS latest firmware.
The 60CSx images are proof of concept, as there is no provision to edit the intro screen image
of the GPSmap 60 series, and the USB screen is also different.

I don't expect many (if any) of the PSP or GPS community to find a use for this,
due to the requirement of both Homebrew capable PSP and Garmin GPS hardware.

I think Apple Ipod firmware can be used with this too, although I don't have one to try.

Greetings to Datrex, and the guys who customised the Garmin etrex for
mountain biking:

I've upgraded to the 60CSX, and keen to be the first to customise it
beyond the ways intended by the manufacturer!
