Thanks!!

@greenhawk84 That's a very nice trick. Until now, I was under the impression that AdvanceMAME was the only arcade emulator where the BIOS files and clones could reside away from a main ROM grouping. Thanks for sharing this.

to answer your second question, i've had good results with this shader set: https://github.com/aybe/RetroArch-shaders just grab the .glsl & .glslp files for the ones you want and drop them in ~/.config/retroarch/shaders

@battlecat One way to do this would be to do the following: Scrape all of your roms to make sure all are listed in the gamelist.xml file. Manually edit the gamelist.xml file (usually located in ~/.emulationstation/gamelists/<system>) to remove the unwanted roms. From the main emulationstation screen, push start, then find the option in the menu that says "Parse gamelist.xml file only" or something like that. Reboot your system, then enjoy! This is how I hide the various bios files as well. Of note, if you add a new system or rom, you'll have to disable the "Parse gamelist.xml" option to see the new roms, unless you've scraped them already. Good luck!

@Freakadude said in Strange cloned RetroPie Image issue!: This is a self backup and restore issue/question. Sorry for assuming you were using a 3rd party image. I hope our fellows posts above helped you. Cheers!

I tried to do the same actions, and then I tried to fix it by this tutorial but it didn't help me anyway. what else could you suggest? thanks

@MajorDangerNine Thanks - I'll check it out.

@mediamogul I am going to try and test these this weekend before adding them all the list but it is a very good list indeed.
