Added <string.h> to the global include list in mednafen.h.
Added boolean setting "debugger.autostepmode" that, when set to 1, will cause Mednafen to automatically start the debugger in step mode after a game is loaded(only if Mednafen has a debugger for the emulated system, of course).
NES: Fixed CNROM emulation initialization bug.
PCE: ADPCM software reset was erroneously also resetting the playback frequency. Fixed. (Fixes ADPCM voices in Gulliver Boy)
PCE: Fixed disassembly of the JMP $(AAAA, X) instruction.
PCE, PC-FX: Improved PSG LFO emulation.
PC-FX: Emulated gamepad button presses weren't being decoded from the driver-side data correctly(causing problems on big-endian platforms). Fixed.
PC-FX: Improved the logging of the ROM font system call in the debugger, to also include the callee address and the size of the glyph being requested.
PC-FX: Disassembly of the "nop" instruction will no longer show the virtually meaningless operand.
PC-FX: Fixed alignment and prettified the disassembly of LDSR and STSR instructions.
SMS: SMS pause and 2-player support were erroneously commented out. Fixed.
