Spu2-X 1.5

Hey guys, In light of recent fixes and additions we prepared a new SPU2-X release for you 😊

This one focuses on SPU2 emulation accuracy but there's also the much requested volume adjustment feature included. You can now try a fake SPU2 reverb mode that may sound better than the (still somewhat broken) original reverb.

Emulation improvements:

• Reverb engine reviewed and mostly rewritten.
• Initialization modified to reflect test results, including a critical portion of the BIOS initialization sequence to support fast boot.
• Hardware reset feature removed because tests failed to prove its existence.
• Possible null pointer access eliminated.
• Added support for reading KON and KOF registers, which is used in the BIOS.
• Improved voice loop logic based on tests.
• Constantly mix the input area and generate IRQs from accessing it.

Among the fixed games are titles such as:

• F1 2005
• Burnout in-game music
• Tomb Raider (the whole series)
• Spyro the Dragon
• Gauntlet Dark Legacy
• Legacy of Kain Soul Reaver 2
• etc

Hope you enjoy, and please report all (new) bugs if you find them!
