+#ifdef PSP\r
+* SVP is not emulated.\r
+#endif\r
 * Various VDP quirks (window bug, scroll size 2, etc.) are not emulated,\r
   as very few games use this (if any at all).\r
-* Some games don't work or have glitches because of inaccurate timing and sync\r
-  between the emulated chips.\r
+* The emulator is not 100% accurate, so some things may not work as expected.\r

 Changelog\r
 ---------\r
+1.40\r
+  + Added support for SVP (Sega Virtua Processor) to emulate Virtua Racing,\r
+    wrote ARM recompiler and some HLE code for VR.\r
+  * Changed config file format, files are now human-readable. Game specific\r
+    configs are now held in single file (but old game config files are still\r
+    read).\r
+  * Fixed a bug where some key combos didn't work.\r
+\r
 1.35b\r
   * PSP: mp3 code should no longer fail on 1.5 firmware.\r
   + PSP: added gamma adjustment option.\r
