+Cheats
+------
+
+PCSX and cwcheat cheat formats are supported. PCSX .cht file can be loaded from
+"extra stuff" menu after game is loaded, while cwcheat cheats are automatically
+loaded from cheatpops.db file, if one is present in emulator's directory and
+has any cheats for the loaded game in it.
+If any of those files are successfully loaded, 'cheats' option will appear in
+the main menu where it is possible to enable/disable individual cheats.

+r15 (2012-08-02)
+* various compatibility fixes
+* attempts to fix various SPU issues
+* Exophase fixed blending issue in his NEON GPU
+* fixed some potential crashes
+* gpu_unai: merged range fix from Franxis
++ added cheat support
++ menu: pressing a key in file list now seeks to a file
++ new code, fixes and refactoring to improve portability:
+  support RAM offset, translation cache in data segment,
+  SDL support, multiple sound output methods, configure script
+* unified plugin names for all ports
++ initial libretro support
+
+r14 (2012-03-04)
+* GLES GPU: implemented frameskip
+* GLES GPU: merged some changes from schtruck/FPSE
+* Caanoo: potential workaround for save corruption
+  (always exit emulator cleanly before turning off the console
+   to reduce chance of corruption)
+* Caanoo: fixed a bug in GTE code (graphic glitches in some games)
+* Caanoo: reworked vibration support, should support more games
+* various refactoring/minor tweaks
+
+r13 (2012-01-09)
+* yet more fixes for regressions from earlier versions
+* various fixes for NEON GPU (in collaboration with Exophase)
++ NEON GPU supports interlace mode now, but it's not always
+  enabled due to frameskip glithes (can be changed in the menu)
+* cdda should resume on savestate load now
+* fixed date display in menus to honour locale
++ pandora: added support for minimizing the emulator (while ingame only)
+
+r12 (2011-12-24)
++ new ARM NEON GPU rasterizer from Exophase (NEON hardware required)
++ new GPU emulation code
++ new analog controller configurator
+* changed frameskip handling (again..), higher values supported
+* fixed several more regressions from earlier versions
+* changed cdrom code with hope for better compatibility
+* sprite optimization for PCSX4ALL plugin
++ Caanoo: added vibration support
+
+r11 (2011-10-31)
++ added Wiz support
+* Caanoo: fixed tv-out
++ Caanoo/Wiz: added scaling (16bpp only)
++ Caanoo/Wiz: added touchscreen-as-buttons input (4 sections)
++ added .cbin support
++ added multidisk eboot support (use "next multidisk CD" in exras menu)
+* some GTE related optimizations
+* various other optimizations
++ added some speed hack options for slower devices
+  (get more speed at stability and correctness loss)
+* fixed several compatibility issues
+* fixed a few crash situations
+* various minor adjustments
+* maemo: merged some code from Bonapart
+* maemo: fixed BIOS issue (hopefully)
