[WANTED] Emulation images for Raspberry Pi 400

I tried the 32 GB “Ultimate Fighters Image from DB” on my RPI-400, but it does not work.
Pity, I had it set up on a table with an arcade stick and a big TV and was ready for some fightan gayms.

The Linux bootup sequence states “Newer software is needed for this board”.

I assumed the Raspberry 400 is a RPi 4 with 4 GB RAM in a keyboard enclosure, but I assumed wrong.

How can I tell what images will work with my model?
Obviously if the NFO says “This is made for RPi3 or RPi3B” it will be incompatible, but what about the variations and regressions amongst RPi4 boards? Is there a list of them somewhere?

Is there a way I can update or rebuild an existing image to work with newer software, or should I just try various images until I find one that works?

Thanks for taking the time to read this!

I tried another random RetroPie image from GoogleDocs, this one was 16 GB.
Same error

start4.elf not found
start.elf incompatible
Newer software is needed for this board

The only thing I get working with this board so far is Pimiga 1.5 Lite.

Perhaps only images that are declared as compatible with Raspberry Pi 400 will actually work.

I wonder if I could update this image just by updating the boot files with the ones from the latest RetroPie 4.7.1…

I tried updating a pre-made RetroPie image to work with my RPi400, thus:

1. Write older, incompatible .img to 32 GB card
2. Write ‘retropie-buster-4.7.1-rpi4_400.img’ to 8 GB card
3. Copy contents of boot folder from 8 GB card to my PC.
4. Use partition tool (MiniTool Partition Wizard Home Edition) to move unreadable data partition to an empty SSD on my PC. Delete the original data partition from 32 GB card.
5. Enlarge the boot partition on 32 GB card. (minimum 312 MB)
6. Copy newer boot data from PC to enlarged boot partition on 32 GB card.
7. Copy data partition from PC to 32 GB card.

This would just produce a blinking text mode cursor in the upper left corner of the screen.

The Partition Tool i used was pretty old, it didn’t recognize the filesystem of the data partition. It may have copied it incorrectly or resized partitions in a way that Linux does not recognize.

Anyone on this forum use a Raspberry Pi 400?

After further research, I discovered that the Pi400 is quite different from the standard Pi4 board. The CPU is different enough so that old Pi4 software will not work on the Pi400. Only the latest kernels and OS builds will support both.

On arcadepunks, I found only two images that support the Pi400:

https://www.arcadepunks.com/cobalto-v4-128gb-recalbox-7-1-1-raspberry-pi4-400-from-galisteo/

and the Pimiga 1.5MF one.

Pity, I  hoped there would be more. :-/

If I wanted to have more builds, I would have to make them myself.
“Roll your own!”, as they say.
That is a bit more time investment than I’m willing to put in, producing an emulation image is an enormous effort.

Time to order big SD card, I guess…

I have a Pi400 and I can confirm that the image “The Big Schmoo” works on the Pi400.  We do need more Pi400 love for future images because it is crazy powerful.
