Due to many variables and compatibility between Cores that support CHD, it is recommended you try out V4 AND V5 in any given circumstance, to ensure you have the most optimal conversion. IE: If you attempt a V5 conversion with PS1 Games, some may have no music if run through CDMage and become .bin+.cue Whereas, a proper .cuesheet would potentially have correct sound. And, due to Arm conflicts, V4 tends to work best for Sega Saturn/Sega Dreamcast. So, until you get the hang of things, try a few different conversions!
