Bitmap Hunter changelog

v5 · May 4, 2009

Hi Guys,Here's an update to Bitmap Hunter for devices 16 bit graphics.Bitmap Hunter is a homebrew program for Sony PSP designed to hunt,and directly edit monochrome, 256 colour, or 16 bit bitmaps within firmware filesfor electronic devices so they can be user customised.Bitmap Hunter has now been tested with Apple Ipod firmware,although I don't own the ipod hardware to try loading it.YouTube Video (shows GPS with modified screens at the end) : is of Bitmap Hunter V4 with 256 colour (8 bit) graphics.This definately marks my retirement from the PSP scene (the programming side at least).I've moved on to my first Windows program, and would like to look into the Apple iphone later on.It would be safe to say this will be my last public PSP program unless I happen to need somethingfor myself in aid of some project that may also suit others.Cheers, Art.

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 devicesso they can be user customised.This one was inspired by HACKBMAP.EXE by Datrex, a DOS applicationused to hunt for bitmaps within Garmin Etrex GPS firmware files.eTrex fan&tuning pageHackbmp.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 imageof 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 formountain biking:The etrex Mountain BikerI've upgraded to the 60CSX, and am first to customise it's graphics that I'm aware of.Cheers, Art.
