 Changelog\r
 ---------\r
-1.4x\r
+1.50\r
+  + Added some basic support for Sega Pico, a MegaDrive-based toy.\r
   + Added proper support for cue/bin images, including cdda playback.\r
-    .cue sheets with iso/cso/mp3/wav files listed in them are also supported.\r
+    .cue sheets with iso/cso/mp3/wav files listed in them are now\r
+    supported too (but 44kHz restriction still applies).\r
+  + Added bin_to_cso_mp3 tool, based on Exophase's bin_to_iso_ogg.\r
+    The tool can convert .cue/.bin Sega CD images to .cso/.mp3.\r
+  * Changed how scheduling between 68k and z80 is handled. Improves\r
+    performance for some games. Credits to Lordus for the idea.\r
+  * YM2612 state was not 100% saved, this should be better now.\r
+  * Improved renderer performance for shadow/hilight mode.\r
+  * Added a hack for YM2612 frequency overflow issue (bleep noises\r
+    in Shaq Fu, Spider-Man - The Animated Series (intro music), etc.)\r
+    Credits to Nemesis @ spritesmind forum. Works only sound rate\r
+    is set to 44kHz.\r
+  + Implemented some sprite rendering improvements, as suggested by\r
+    Exophase. Games with lots of sprites now perform better.\r
+  + Added better idle loop detection, based on Lordus' idea again.\r
+  * "accurate timing" option removed, as disabling it no longer\r
+    improves performance.\r
+  * "accurate sprites" was removed too, the new sprite code can\r
+    properly handle sprite priorities in all cases.\r
+  * Timers adjusted again.\r
+  * Improved .smd detection code.\r
+  * ARM: fixed a bug in DrZ80 core, which could cause problems in\r
+    some rare cases.\r
+  * ARM: fixed a problem of occasional clicks on MP3 music start.\r
+  * Minor general optimizations and menu improvements.\r
+  * Fixed a bug in Sega CD savestate loader, where the game would\r
+    sometimes crash after load.\r
   * Fixed a crash of games using eeprom (introduced in 1.40b).\r
