Resource Hacker Tool For The Boot .img

A tool to mod the boot.img and input your own boot up screen.
Warning: I haven't tried it myself. I don't have the facilities to unbrick my GP2x so I rather not mess with the bootloader.

This tool should allow you to edit the boot.img image of the 3.0 firmware. If you are brave you are allowed to try it out, or if you know how to unbrick your GP2x in case it messes up.

I've used a simular trick to edit the bootscreen of my MP3 player, but that was not in the bootloader. It does nothing more then extract the image located in the bootloader to a BMP (converting it to 32bit) and putting it back in (converting it back to 16bit at which it was in)

You do realise that messing with the bootup screen is dangerous, and likely to turn you 2x into an expensive paperweight unless you have jtag equipment and software to resurrect it?
 
Oh joy,

People, please realise this scores very low on the common sense level ;).

If you really must customise the boot screen in your bootloader your better off building your bootloader from the source itself. The exact image locations can change on each build and running a tool such as the one above on the wrong gp2xboot.img is going to pop the image right over needed code.

Sure its a pain to build your own and not a simple task but at least your can test it before you flash it to your GP2X and brick it. Anyway, touching the bootloader without jTAG and ways to debug it and ensure its ok is a mugs game, the GPH supplied bootloader updates are flaky enough as it is :p.

Why people seem to insist on wanting to do this on the GP2X is beyond me as unbricking can very often not be straightforward (even with a BoB and all the hardware I frequently have to tweak my software to overcome new and interesting bricks that have come to me to be fixed after others have tried)

You would not change the bootlogo on a PSP as you would except it to leave you with a £100 paper weight, give the same credence to doing it on the GP2X.

Changing the kernel logo is another matter entirely as that is an all together safer thing (though still not without risk). I even added status updates to the Open2x kernel boot screens recently to show where in the boot progress you are and information on how to customise it if anybody is interested is here (in fact I would love any offers of help to create some boot 'themes' :D).

I read your link, do you have any screenshots or video captures you can show us? For design purposes, it would help theme artists to visualize the boot-up sequence.

I put a thread in general about just that (rather then take this off topic). I will try and add some images later tonight. I have a few ugly looking themes in the current kernel source but it's a little hard to take screenshots ;).

Well the bootloader could be modified to use a custom image the same way as gph one uses custom sound from NAND, not from the boot area.

Agreed (in fact that is just what some of the Open2x bootloaders do) but it does not detract from the fact that the stock booloaders have the image embedded in the binary :D. It would also require a little thought about the NAND layout if you wanted to keep GPH firmware compatibility as that makes lots of assumptions about were things are.
