Update and roms not working

[RetroPieVin]

Hi,

I updated an old retrofit installation from 2.8 to 4.4. Now a lot of my roms are not loading. Any ideas how to fix or should I re-install old version.

Thanks

Isn't 4.4 several jumps in operating system? I can't imagine you could successfully make that kind of update directly. 4.3 was on Jessie and 4.4 was on Stretch. That alone makes 99% of folk have to restart from a new image.

@RetroPieVin Did you upgrade using the Retropie script?

@Thorr69 It depends on how they did it. If you use the Retropie script, you can update the Retropie portion up to 4.4 on Jessie Raspbian. Version 4.5 dropped Jessie support and you had to start fresh to upgrade to 4.5. If you attempt to upgrade the distro underneath, that is where the problems quickly come into play.
