@quicksilver my prayers have been answered. They added an uninstall function today!

I know this is an old post but it's the only one I can find that has a similar issue especially with SNES. I'm assuming it has to do with I have donkey Kong rev a and the the image for the bezel doesn't have that name

@zfa said in Retropie Bezel Project & lr-mame2003 cfg does not persist after update?:

I guess the real fix is to get The Bezel Project guys to use the names as per the Retroarch guys, or make sure they include symlinks where there are name changes across versions of a core. If this doesn't work then update your emus again in case you have a version reporting itself as being mame2003 as per @Virtualman post.

This name change/folder change came from RetroArch leadership rather than the mame2003 core. The code logic for this is kind of obscure but it has to do with enabling netplay between a broader range of different systems.

Based on the RA rationale for making the change I expect it will be permanent.
