redream not working

mitu

Then I suggest you reinstall again redream. The package does contain the file not found in your error (/opt/retropie/emulators/redream/redream.aarch64.elf).

It does contain redream.aarch64.elf, it's referenced in the redream script we were having problems with. See image for my directory structure and files

You say you installed RetroPie using the RPI Imager image, but your image shows a newer kernel and a 64bit system (?), which we don't include. Did you use rpi-update to update your system by any chance ?

I don't specifically remember doing so but it's quite likely i have at some point done rpi-update.

I noticed an issue with the symlinks last night so I'm going to investigate that but I'm AFK right now. I'll come back with my findings.

Why ? rpi-update is not meant to be used for regular updates, it even tells you so when you run it. Your bootloader and kernel have been upgraded to the latest beta and that's why your system is running a 64bit kernel, but with a 32bit system. it's most likely the reason redream doesn't work since it thinks the system is 64bit, but the aarch64 (64bit) executable cannot run on a 32bit userland.

You can either re-install the relevant packages to remove the beta kernel/bootloader or add arm_64bit=0 to the booloader configuration file (config.txt, in the /boot folder).

Thanks @mitu

I'm going to check to see if the symlinks issue is the problem first (it seems as tho the bios files symlinks are not working, I've not fully investigated but it seems nothing happens if I try to 'cat' the bios files). If that's a red herring then I'll try to force 32bit mode as advised. I'll update the post as usual. Thanks again for your help.

Cheers.

I finally got it sorted out thanks to you, the issue was indeed was the 64/32 bit mismatch. Forcing 32 bit mode with arm_64bit=0 and fixing the issue with the symlink that points to the bios fixed it. Thanks so much for your help and patience, im so releived to have finally got it fixed. I couldnt have done it without you! Cheers!

@c0un7z3r0 Glad you got it working. Also, don't use rpi-update again for regular updates.

@mitu Will do! Thanks!

@mitu This was the cause of my issues. More info here.

My issue was also fixed by adding arm_64bit=0 to /boot/config.txt.
