Mednafen v0.9.33.1 WIP Changelog:

March 8, 2014: Fixed compiler errors when compiling without the debugger. Fixed a couple of memory leaks. PSX: Made better use of exceptions in the loading and initialization code paths(and avoid leaking memory if a part of the process fails). PSX: Protect against sound buffer overflow without causing a call to abort() so that using save states(when they're added) or power toggling/resetting in the debugger while in step mode is safer. PSX: Output of debug messages to stdout and stderr is now controlled via the "psx.dbg_level" setting, whose default value of "0" disables almost all debug messages. Set the setting to "3" to obtain roughly the same output as previous versions of Mednafen. March 1, 2014: Modified the simple interpolation pixel shader code to avoid using the GLSL 1.3 function "round()", for better compatibility with some OpenGL implementations.
