I got the new 2GB one in and sadly it seems to be to new for the image, I get the dreaded start4.elf is not compatible, this board requires newer software.

Yes, there have been quite a few topics in the forum with this error - the solution is to use the weekly build image from https://files.retropie.org.uk/images/weekly/.

@mitu Yes thanks, I read about it. I will try to see if just the start4.elf and recovery4.elf will make my old SD card come alive.

Just replacing the start4.elf actually made it boot into the intro video, but after the video I just get a black screen.
At least one step further!

I had to setup my retropie from scratch to get it to work on the Pi-400 and the new 2GB Pi4B I got.
I got almost everything working except some of the openbor games (the script mentioned in the emulator section on the site does not seem to be in my image).

The biggest issue I have now though is that for GBA, GBC and GB games the games will only show in the top left quarter of the screen. No matter the retroarch setting I change, and no matter the resoltion I choose in the launch menu, nothing changes this.
The games are playable if I disable the basel, but I am confused because GBA was actually the first system i got working on my new install, and it worked fine.
After getting the rest of the systems working I went back and the resultion changed just on these 3 nintendo handheld systems. So instead of rendering in the center of the screen as usual, it renders the whole image in the top left of the screen at 1/4th the usual size as if the top left quarter of my tv is the whole screen.

Do you have any idea what could have caused this?

Then disable the bezels, looks like it's an issue with them.

What I meant is that since its in the top left corner of the screen, the bazel will cover up most of the image, but if I disable the bazel, the whole image will be visible but still in the top left quarter of the screen.

@infyra This doesn't look like a standard config - how did you install the bezels ?

Infyra

@mitu
I can't remember installing them, dont they come with the image? Maybe they were in my old folder on the USB and retropie imported them too.
Anyway, I figured out how to move the viewport to the center of the screen, if I enable the integer scaling under scaling options in retroarch it will move the picture to the center, and then I can pump it to about 10x so it will fit the bazel.
If I don't use integer scaling I can move it to the center of the screen manually by adjusting the x and y of the viewport, but in either case, I cannot get retroarch to save the configs in the /opt/retropie/configs/gba/retroarch.cfg folder.
I have manually saved a config and overwritten the retroarch.cfg but it seems it will only enable the integrer scaling without keeping the 10x configuration.

I have also tried these instructions: https://retropie.org.uk/docs/Smaller-RetroArch-Screen/
However, adding these to the config does not do anything for me:

Adding these lines to the config doesn't move the viewport when I start a GBA game:

aspect_ratio_index = "23"
custom_viewport_width = "720"
custom_viewport_height = "480"
custom_viewport_x = "600"
custom_viewport_y = "300"

Thanks for all the help so far!

Bezels are not provided by RetroPie and they need to be configured manually or by installing the packs provided with the Bezel Project.
You'll have to find the configuration of the bezels, which should be a .cfg for the system and/or for the game, and adjust there the settings (viewport size, resolution).

@mitu
Thanks for all the help, I finally figured it out. There was a directory config overwriting in the folder with the bios config, when I removed that one my own configs worked and everything is now perfect.
