Case sensitivity INSIDE another file has gotten me multiple times.

@mitu I have been trying to run Flink(U) and Dragon's Lair @quicksilver thank you, I was going to try that it's nice to have a confirmation beforehand

It is from MAME 0.205 (x64) release.

@Dinsdale The bios for picodrive can basically be copied and renamed to bios_CD_U.bin bios_CD_E.bin bios_CD_J.bin and then the cd should work for lr-genesisplus-gx. The audio seems to be baked in with the .bin, this usually will work so I don't know why it isn't. Maybe the .cue has a line break edit that make it incomplete, and you could try checking for carriage returns with edit+, maybe the emulator accepts them anyways. Could try searching for a method to separate the audio tracks. extract audio from segacd. Or try to convert to CHD with chdman; "sega cd .cue to .chd"

@mitu Yes I tested them on PC and they aren't working on PC either so definitely seems to be a problem with the files themselves. Here is a pastebin of the info command: https://pastebin.com/s6g48Nr7

You can use iso+ogg for more space (edited with cue files) with games who have many sound track and lr-genesis-plus. Turborip is fine for compress in that format. Chd is fine too and more easy, but more heavy in general. Picodrive use cso+wav but i don't use it.

@tommyellas Please read the forum's rules - https://retropie.org.uk/forum/topic/2/forum-rules, there's no ROM/bios/games sharing.

@saccublenda Ive found switching between discs was an issue when select-x to retroarch menu When using bin. and .cue roms. Try using just .iso roms for mutli disk games like night trap and ground zero texas. Worked for me

@Shmeter.man are you using a thumb drive to put the bios on? There are issues with the sega cd bios' and that method. Use something like winscp to put the bios files on.

@meleu I think RetroArch doesn't care about extensions... Jeezy Creezy.... It was just that easy. Ahhhhhhh well. At least when I'm wasting a ton of time and the answer is just this simple at least I'm learning new things, right? I absolutely can't believe the best answer was changing .bin to .cue. Works perfect for launching the game, and it shouldn't give any problems with our script either. Thanks everybody!

@RobotLimeLtd That is not the default for retropie - default retropie has # Sets the "system" directory. # Implementations can query for this directory to load BIOSes, system-specific configs, etc. system_directory = "/home/pi/RetroPie/BIOS" in configs/all/retroarch.cfg - perhaps you overwrote the config?
