Namco pacman rasp pi compute module 4 based arcade game software update failed any idea how to fix

Looking for suggestions on how to fix my file I have the update from namco https://bnaa.wetransfer.com/downloads/2ca4d18225c4ac60618888c9bdbfa41920230915172535/1d6a03 and the old SD card with a lot of files still on it, but seems to boot to black screen now like its in some update mode... any idea what I can do to try and save the SD card?

Seems to run on raspbian

SD cards is prone to fail, check it for faults.

The SD card is fine, it was a failed update and they do not have to software available to image a new one. I am not sure what is broken on it to prevent booting

I found a modified version someone apears to have made from the original but I’ve reversed some of it and can get it to boot to the initialization screen does not seem to get past there.
