 About

-This version of PicoDrive is another enhanced version of Dave's
-Megadrive / Genesis emulator for Pocket PC, which now can also emulate
-Sega/Mega CD. The original Dave's code was heavily modified (including
-Cyclone core), parts of it were rewritten in asm, many features added,
-accuracy increased. Sega/Mega CD emulation is mostly based on Gens code.
-This version is aimed at ARM-based handheld devices, so ports exist for
-GP2X handheld console, Symbian smartphones and other devices.
+This is yet another Megadrive / Genesis / Sega CD / Mega CD emulator, which
+was written having ARM-based handheld devices in mind (such as PDAs,
+smartphones and handheld consoles like GP2X of course). The critical parts
+(renderer, 68K and Z80 cpu interpreters) and some other random code is
+written in ARM asm, other code is C. The base code originates from Dave's
+(fdave, finalburn) PicoDrive 0.30 for Pocket PC. The Sega/Mega CD code is
+roughly based on Stephane Dallongeville's Gens.

 Changelog
 ---------
-1.2x
+1.32
+  + Added some new scaling options.
+  + Added ability to reaload CD images while game is running (needed for games
+    with multiple CDs, like Night Trap).
+  * Fixed DMA timing emulation (caused lock-ups for some genesis games).
+  * Idle loop detection was picking up wrong code and causing glitches, fixed.
+  * The ym2612 code on 940 now can handle multiple updates per frame
+    (fixes Thunger Force III "seiren" level drums for example).
+  * Memory handlers were ignoring some writes to PSG chip, fixed (missing sounds in
+    Popful Mail, Silpheed).
+  * Improved z80 timing, should fix some sound problems.
+  * Fixed a bug with sram register (fixes Phantasy Star 4).
+  * Added code for PRG ram write protection register (Dungeon Explorer).
+  * The memory mode register change in 1.31 was unsafe and caused some glitches in
+    AH-3 Thunderstrike. Fixed.
+  * Fixed a file descriptor leak.
+
+1.31
+  * Changed the way memory mode register is read (fixes Lunar 2, broken in 1.30).
+  * Fixed TAS opcode on sub-68k side (fixes Batman games).
+  * File browser now filters out mp3s, saves and some other files, which are not ROMS.
+
+1.30
   + ISO files now can be zipped. Note that this causes VERY long loading times.
   + Added data pre-buffering support, this allows to reduce frequency of short pauses
-    in FMV games, but makes those pauses longer.
+    in FMV games (caused by SD access), but makes those pauses longer.
   * Fixed PCM DMA transfers (intro FMV in Popful Mail).
+  + Properly implemented "decode" data transformation (Jaguar XJ220).
+  * Integrated "better sync" code into cyclone code, what made this mode much faster.
+  * Fixed a bug related to game specific config saving.
+  * Frameskipper was skipping sound processing, what caused some audio desyncs. Fixed.
+  * Fixed reset not working for some games.
+  + New assembly optimized memory handlers for CD (gives at least a few fps).
+    Also re-enabled all optimizations from 0.964 release.
+  + New idle-loop detection code for sub-68k. Speeds up at least a few games.
 
 1.201
   + Added basic cheat support (GameGenie and Genecyst patches).
