Hello, first time post here. I’ve been following the guide to the letter, as this is my first time trying this project. I lost the ability to launch roms after installing the PiTFT due to an error(partially my fault). At the end, it mentions to edit the runcommand.sh to add a DMT-87 mode in order to prevent from switching the HDMI resolution. First off, I was using the 3.0.0 Beta2, so there is no get_mode() function in runcommand.sh. I improvised and added it anyways in the get_parameters() function. This was my error, as I should have just skipped the step and not added it anywhere. If you add the line, it results in a blank screen on the PiTFT and you can’t do anything. I experimented with a lot of settings and moving that line in a few places before realizing that I should just delete it and try it out. Just posting this so it could help someone not waste a couple hours like I did, or maybe it should be added to the guide. I haven’t tested it any further than launching a couple roms, but for now I’m just assuming that the latest beta doesn’t require us to add that line.
