0.4.1 ----- *New Features* - Basic support for the Saturn Keyboard adapter peripheral - You can now navigate up to a drive selection on Windows - Added support for binding more "special" keys *Bugfixes* - It's now possible to navigate to the root directory on Unix-like systems - Fixed a bug in movep.l - Fixed a crash bug in the memory management code - Fixed a bug in the header parsing code, that caused a crash when the "International Name" field was empty - Fixed some minor graphical corruption in Sonic 2 split-screen caused by a bug in vflip combined with interlace mode - Corrected the PC value pushed onto the stack for line A emulator and line F emulator traps - Fixed a bug in ensure_dir_exists that would cause it to fail to create directories in some cases when mixed path separators were used - Fixed a bug that would result in a buffer overflow when starting a game with a long title from the menu *Accuracy/Completeness Improvements* - All Z80 instructions are now implemented - Z80 Half-carry flag is now fully implemented - Implemented undocumented Z80 flag bits - R register is now incremented appropriately - Redundant opcode prefixes are now handled properly - Z80 core now passes ZEXALL! *Other Changes* - Added Buck Rogers to the ROM DB - Added Wonder Boy in Monster World to the ROM DB (for real this time) - Added Evander 'Real Deal' Holyfield's Boxing to the ROM DB - Slightly better handling of directory read errors - Added "Special Thanks" to About menu - Use local app data folder for saves and config files on Windows rather than Unix-style locations 0.4.0 ----- *New Features* - Genesis ROM based Graphical User Interface - command line is no longer required for basic functionality - Added support for the Mega/Sega Mouse - Configurable low pass filter - 68000 overclock and underclock - Scanlines can now be controlled via the config file and defaults to off (previously was always on) - VSync can now be specified via the config file and defaults to off (previously just used the OS/driver default) - Fullscreen mode can now be specified via the config file in addition to the command line flag - New 68K debugger command 'co' allows a list of commands to be run each time a breakpoint is hit - 68K debugger now supports the 'di' command like the Z80 debugger - New debugger command 'yt' displays YM-2612 timer info - Added support for controller hotplug (game controllers don't need to be plugged in before starting BlastEm) - IO devices can now be automatically configured by ROM DB entries *Bugfixes* - Fixed calculation of window start column - removes graphical glitches in Afterburner 2, Fireshark, Dungeons and Dragons: Warriors of the Eternal Sun and probably others - Fixed the implementation of LDD and LDDR - Fixed ABCD/SBCD - eliminates the score counter problem in Bubsy - Fixed btst when used with immediate destination - Fixes a crash in NHL 95 - Fixed YM-2612 attack phase and sustain level - Fixed mapping of YM-2612 key on/off bits to operators - Fixed YM-2612 LFO AMS shift values - Fixed YM-2612 LFO phase modulation - Fixed mapping of registers to operators in Channel 3 special mode (for real this time) - Fixed a small bug in YM-2612 timer reloads - Fixed peripheral ID for 3-button pad - Accesses by the 68K to the low 4MB of the address space, but outside of the defined ROM will no longer cause a crash - Config files and shaders saved with Windows-style line endings will no longer fail to load - Fixed a crash bug on Windows by properly detecting invalid destination modes for immediate variant opcodes *Accuracy/Completeness Improvements* - All 68000 instructions are now implemented - Implemented 68000 privilege, address error and illegal instruction exceptions - Z80 half carry flag is now implemented for the trivial cases - Fixed timing of the Z80 IM and certain LD variants - Implemented interrupt latency - Fixes Sesame Street: Counting Cafe - Interrupts are know acknowleged based on what the VDP thinks its asserting rather than what the 68K actually is acking - Fixes Fatal Rewind - Improved timing of 68000 interrupt processing - Improved timing of Z80 busack response - Fixes a crash in Barkley: Shut Up and Jam - Adjusted the amount of time the 68000 is blocked during DMA - gets rid of remaining part of "YOUR EMULATOR SUX" text in overdrive - Corrected order individual words of a longword are written when the predecrement addressing mode is used as the destination of a move instruction - Adjusted relationship between Horizontal counter and render events to better match tests/measurements - Adjusted vertical interrupt timing to better match measurements - Improved timing of 68K/Z80 interactions based on tests *Other Changes* - Z80 disassembler now supports a start offset parameter: -s - Windows build now uses link time optimization like the others - Optimized the VDP code - Improved audio resampling - Added Mega Man - The Wily Wars to ROM database - Added Wonder Boy in Monster World to ROM database 0.3.1 ----- *New Features* - BlastEm will now open a new terminal window when starting the debugger if it's not attached to one - Errors are displayed in a message box if no terminal is attached - Pure SDL render path for when OpenGL 2 is unavailable (thanks Higor EurÃpedes) *Bugfixes* - GDB remote debugging works again - Fixed a name conflict that prevented vgmplay from being built on OS X *Other Changes* - Windows build now includes the disassemblers, VGM player and save state viewer 0.3.0 ----- *New Features* - 32-bit x86 CPUs are now supported - BlastEm is now available for OS X and Windows - Finished support for the Sega mapper used by Super Street Fighter 2 - Added support for EEPROM saves - Added support for large flat-mapped ROMs (used by some homebrew ROMS) - New 68K debugger command bt (backtrace) - I/O devices (gamepads and other peripherals) can now be configured in blastem.cfg - VDP Debugger views from before 0.1.0 have been restored *Bugfixes* - Partial emulation of floating bus bits for certain I/O regs (fixes Super Offroad 2) - Fixed shadow/highlight mode - Implemented AM and fixed LFO update speed - Fixed negative detune values - Corrected register to operator mapping for channel 3 special mode - Initial stab at emulating cycles being stolen from the 68K when the Z80 accesses its bus - Better handling of creating a savestate in "uncooperative" games/demos -
