as very few games use this (if any at all).\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. Credits to Exophase and\r
+ Rokas for various ideas.\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 when new one is missing).\r
+ * Fixed a bug where some key combos didn't work as expected.\r
+ * Fixed a regression in renderer (some graphic glitches in rare cases).\r
+ * Adjusted fast renderer to work with more games, including VR.\r
+ * Fixed a problem where SegaCD RAM cart data was getting lost on reset.\r
+ * Greatly reduced SegaCD FMV game slowdowns by disabling read-ahead in the\r
+ Linux kernel and C library (thanks to Rokas and Exophase for ideas again).\r
+ Be sure to keep "ReadAhead buffer" OFF to avoid slowdowns.\r
+ + PicoDrive now comes with a game config file for some games which need\r
+ special settings, so they should now work out-of-the-box. More games will\r
+ be added with later updates.\r
+ + Files now can be deleted by pressing A+SELECT in the file browser.\r

\r
1.35a\r

graphics corruption in EU Mega CD model1 BIOS menus.\r
+ PSP: added additional "set to 4:3 scaled" display option for convenience.\r
