+0.9-2xb u4 (unofficial notaz release, done on Exophase's request)
+- Wiz port. No emulation related changes.
+- Wiz: dropped SDL for video and hitting hardware directly (GPH SDL can't
+  be trusted, it doesn't do double buffering as of firmware 1.0).
+- Added new optimized software scaler with interpolation.
+- gpSP is now saving ROM dir on exit. Delete romdir.txt if you don't
+  want that.
+- gpSP now comes with wARM, new kernel module+lib for ARM cache control
+  (replaces mmuhack).
+- gpSP no longer invalidates whole icache after recompilation, might
+  case minor speedup.
