Hardware Changes in the SCPH-5502 (V30 era):
- CD-ROM Controller: Switched from the DSP (CXD1815Q) to a newer DSP (CXD2545Q). The V30 BIOS contains the optimization tables for this new chip, allowing it to read CD-R media slightly better than the launch model.
- Sound RAM: Reduced noise on the SPU (Sound Processing Unit). The V30 BIOS tweaks the DMA timing to prevent audio skipping during heavy 3D loads.
