+ Added data pre-buffering support, this allows to reduce frequency of short pauses\r
in FMV games, but makes those pauses longer.\r
* Fixed PCM DMA transfers (intro FMV in Popful Mail).\r
+ + Properly implemented "decode" data transformation (Jaguar XJ220).\r
+ * Integrated "better sync" code into cyclone code, what made this mode much faster.\r
+ * Fixed a bug related to game specific config saving.\r
\r
1.201\r
+ Added basic cheat support (GameGenie and Genecyst patches).\r
