- The range of the audio buffer size is now 1~3072 samples.
- Corrected a bug in the PSG code that affect the starting phase of the waveform generators.
- Separated the emulation of the two low-pass RC filters(DUO-R) from the BLEP audio synthesis.
- The high-pass RC filter(DUO-R) now use floating point numbers instead of integers.
- Optimized version of the BLEP synthesis for processors that support the SSE2 instruction set.
