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.

eTrex fan&tuning page

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 am first to customise it's graphics that I'm aware of

Hi Art,

Another quality release! I was thinking - would it be possible to extend this to png files? My thought is this tool would actually be excellent for the language translation of homebrew (i.e. the text held as png graphics within the PBP, that you cant amend with a hex editor). At the moment I need to extract the png files, fire up a graphic editor, then repack the PBP. It would save alot of time and would also be applicable to a wider audience. Anyway just a thought...

cheers

This is an absolutely wicked app Art! Should work with almost any mp3 player firmware.

Thanks
This was supposed to be my first Windows program, but I've had trouble with the last
two CDs that the C++ biulder came on, so I decided to do it with the PSP.
Pls let me know the results if you find another device to work with.

@ rosera,
It would be possible in theory, but work different.
You wouldn't be able to see a png until you selected the exact start offset since they are compressed,
which would make searching this way slow, but since png headers would be intact for homebrew,
a program could just search an eboot and easily find them by itself.

You could easily start developing Win/Linux/Mac Apps with the Qt SDK (that is a nice IDE together with MinGW compiler and Qt Gui/Network/etc. Library bundled together). It's free and licensed with GPLv3 and LGPL and defo worth a look

If you fancy .Net I would rather take Visual Studio instead of C++ Builder.

I only chose Borland C Builder because a friend has it, and I can get plenty of real life support.
I would opt for anything closer to C programming for the PSP to make the transition easier.
It's a bit overwhelming.

Ha ! This is awesome !

Thanks for this Art. You truly have passion for programming.

Hi,
Thanks,
I have a 16 bit mode now, which is what was needed to edit colour ipod software.



Just haven't quite got a release package ready.
Got the Windows stuff happening too, already on my first project
