I appreciate the link @JoeViking245, however I believe I have followed everything there. For additional info of my dilemma: Playstation games in a BIN and cue format work fine I only have one PSP game in ISO format, as opposed to CHD and it is the only game detected in LaunchBox However, if I boot up Ape Escape: On The Loose from that screenshot you can see this is the correct hash and is detected by Retroarch and RetroAchievements appropriately

I have a large collection of games, most of which are detected correctly in LaunchBox when it comes to RetroAchievements. However, after much struggle I noted certain compressed file types such as CHD (PS2 / PSP) and RVZ (GameCube) are not recognized by LaunchBox. I can confirm that these are RetroAchievements compatible hashes from the source acquisition and detection when launching the games in RetroArch, Dolphin, etc. Is this a known limitation of LaunchBox that is mentioned anywhere for users to know, or something that the LaunchBox or RetroAcehievements teams are looking to fix?
