Bitmap Hunter V3
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 image is proof of concept, as there is no provision to edit the intro screen image of the GPSmap 60 series.
I don't expect many (if any) of the PSP or GPS community to find a use for this, due to it's nature,
and the requirement of both Homebrew capable PSP and Garmin GPS hardware.
Greetings to Datrex, and the guys who customised the Garmin etrex for
The etrex Mountain Biker
I've upgraded to the 60CSX, and keen to be the first to customise it
beyond the ways intended by the manufacturer!
