This release fixes performance regressions introduced in v0.5r870, particularly when streaming audio is playing, and fixes a cause of high interrupt latency with SD Card Adapters.Soulcalibur II is an example of a game sensitive to interrupt latency, where the graphics processor can easily crash.@Extrems committed:

• Less hacky kickstart for ISR.
• Optimize streaming audio decoding.
• Bundle boot.iso for GCLoader.
• Reinstate partial read buffer.
• Omit lock for non-disc reads.
• Move start block token to ISR.
• Don't force video mode if video mode is unavailable.
