-- 1.21.2: --April 2, 2018:Updated bundled copy of Tremor to address a security vulnerability.SS: Improved emulation of SCU DSP DMA to program RAM, per tests on a SS(still nowhere near perfect, the way it's implemented on hardware is kind ofhorrible, but it should work ok if games use it how it's meant to be used); fixes graphical glitches in "Shining Force III - Scenario 2", and perhapsin the other "Shining Force III" games as well.SS: Flush the prefetched SCU DSP instruction when PC is set via PPAF, instead of when END/ENDI executes or when execution is forcibly stopped, per tests on a SS.SS: Disallow SCU DSP LOP from being written in a looped single instruction unless it's the final iteration, per tests on a SS.SS: Allow SCU DSP LOP to underflow to 0xFFF with LPS and BTM, per tests on a SS.
