Here's an actual translation - into English rather than gibberish - by a human:
Many changes in prototype R13: tentative implementation of DSP and 68000 instructions, VDP2 graphics handling, CD block rebuilding, and dynamic recompilation, etc.
I guess the big change is the introduction of dynamic recompilation of SH2 instruction handling. But that doesn't work with some software, so it looks like some work is still needed. There's an option to toggle dynarec on and off.
Despite much effort, I haven't managed to get the graphics working in "Dead or Alive" or to fix the crashes in "Radiant Silvergun". I can't work out what the problem is... so for now I'm ignoring it and working on other things.
So, I guess the next thing will be to implement SCSP. Emulating it properly would be hopelessly complicated, so I'm trying to think of a way to fudge it.
