| CLEARSPU || Clears/resets the SPU2 by setting the registers to a known state and zeroing SPU2 memory. If the SPU2 asserts an interrupt when this library is active, it will cause a bus error due to the fact that the callback function is set to NULL. Only used by the OSDSYS of the SCPH-10000 and SCPH-15000, probably retained for backward-compatibility. Appears to use an older version of the libspu2 library. ||

For 2.20+ ROMs, if high bit of 0xBF801450 is set, ROM region is read with SCMD 54/0x36 and patched using 0xFFFE0180 and 0xFFFE0184, MAC address is read with SCMD 55/0x37 and is loaded to 0xFFFE0188 and 0xFFFE018C, and 0xFFFE0190 is set to byte at offset 1 of EEGS config (config 0). ||

| OSDSND || OSD sound library. This is a combination of the tentative libraries "libspu2", "libsnd2", "rspu2drv" from the PS2 runtime library, which are mostly ports from the PS1 runtime library.

However, it does not contain the VSync/Alarm based callback code that is in libsnd2 in SDK 1600. ||
