kalymos 1db7d37c05 Added support for the SCPH-5903
The mod for this model was developed by analyzing signals and adjusting the lead-in frames to accurately distinguish game discs from Video CDs (VCDs) and audio CDs. Additionally, this update fixes an issue where game discs were occasionally misidentified and read as music discs.
