Some help editing the Custom Boot Animation for CFW on Powkiddy V90

[MajorBS]

Hello, all.

I am currently customizing a Powkiddy V90 for a good friend of mine as a gift. I see from other discussions here that the file is not video but an actual programmed sequence that plays out with a .png file that scrolls down with the Game Boy start up audio.

The only thing I'm looking to edit would be the .png with different wording and since I have 0 programming knowledge and no access to Linux I was wondering if anyone would be able to help me out to generate a replacement boot-logo file.

Thanks for your help in advance.

This is going to be a bit dumb, but probably the easiest method for a one-off:

1. Fork this repo: https://github.com/MiyooCFW/logo
2. Upload your image to http://tomeko.net/online_tools/file_to_hex.php?lang=en to generate a big 0x... string
3. Edit your fork of https://github.com/MiyooCFW/logo/blob/master/assets.h - overwrite the existing 0x... string that covers lines 112-153 in with the new one from step 2
4. Also copy the 0x... string into https://tools.knowledgewalls.com/noofcommascounter to get the number of commas
5. Edit the number on line 111 of your assets.h be the number of commas from the previous step + 1.
   E.g. if it had 99 commas, then you'd change the line to 100:
   static unsigned char png_logo_powkiddy[100] = {
6. Commit your changes.
7. Go to the Actions tab on your fork, wait for the CI build to complete, and download the Powkiddy boot logo
8. Copy it to your microSD, overwriting the boot-logo file in the main partition.

I'm not 100% sure this will work, as we're mixing between tool chains. If the logo compiles but doesn't work on your device, try changing this line in your fork to image: nfriedly/miyoo-toolchain:steward and then wait for another build to complete.

Thank you for the reply.

Unfortunately I do not understand most of the nomenclature you are noting. What does "Fork this repo" mean and how do I accomplish it? Does that require linux or a virtual machine. If so unfortunately I do not have access to it.

As an example, here is the image I would be attempting to replace the "Powkiddy®" logo with in the boot-logo file:

I'll do what I can to explain it, but this might be beyond your capabilities.

What does "Fork this repo" mean and how do I accomplish it?

Go to the link in step 1. and click the "Fork" button in the upper right. Here's more info: https://docs.github.com/en/get-started/quickstart/fork-a-repo

No, that's part of why I called it "dumb" - we're using GitHub's infrastructure to do everything. The only thing you need to do outside of your web browser is copy the boot logo over to the microsd.

Thank you for the explanations. Very helpful.

I have completed what you noted at https://github.com/MajorBS/logo/blob/master/assets.h. I think I did it correctly.

I went to the actions tab > CI Build but I do not see any tools to download a new copy of "boot-logo".

[nfriedly]

Huh, that's strange. I thought the Actions stuff would be enabled by default. There's probably a way to turn it on in settings, but I just set up a Pull Request from your fork to mine, mine is running Actions - you can download the logo from here: https://github.com/nfriedly/logo/actions/runs/4399541295

[MajorBS]

Thank you very much. That worked perfectly!
