Atari ST/STE emulator

Version 0.90 (2006-08-22):

--------------------------

 

- Better Spectrum 512 support (60Hz support, improved I/O memory waitstates).

- STE right border opening support (used in Obsession, Pacemaker).

- Blitter Smudge mode support (used in Pacemaker demo).

- Wheel-mouse simulates cursor up and down.

- Work-around to FDC handling, --slow-fdc option is not anymore needed.

- Bugfix to MFP, sound works now in more YMRockerz releases.

- Bugfix to GEMDOS path handling (Hatari SIGSEGV).

- Bugfix to emulated memory initialization (4MB was cleared earlier, now exactly the amount set up for Hatari. Saves memory on embedded systems if less than 4MB is specified.)

- Re-written command-line option handling.

- (Again) lots of code const/static, type usage and indentation cleanup.

- Preliminary support for TOS 3.0x and 030 TT software that runs in ST resolutions and doesn't need PMMU.

- Native GUI for Mac OSX.

- ACSI emulation fixes to get HD formatting to work with AHDI 5. HD emulation now works quite fine with AHDI 5 (but other HD drivers are currently not supported).

- Joystick shortcut changed to toggle cursor emulation between ports 0 and 1.

- Keys for all Hatari shortcuts can now be configured from hatari.cfg.

- Added command line option for setting ST keyboard mapping.

- Joystick command line option requires now parameter for a port for which the joystick cursor emu is enabled.

- Fixed relative mouse event handling in zoomed low-rez.

- Hatari shows now more of the bottom borden (screen size is now 384x276 instead of 384x267).

- Fixed sync delay timings - sound should now be better (e.g. on Mac OS X).

- Added basic support for compiling Hatari with MinGW.

New MAME GP2X 2.5:

 

Added the modifications done by Slaanesh for MAME GP32 2.2 (WEB):

- Sample support!. Several games have full sound now (Phoenix, Donkey Kong, Zaxxon...). The samples are available for download HERE.

- Z80 C core updated for improved compatibility. New games fully working (1942, Jungle King, Crazy Climber...).

- Rearrange Taito sound effects driver to take priority over music channels. Means sound effects play now (Jungle King, Alpine Ski...).

- Improved drivers: Berzerk, Frenzy, Quantum, Battlezone and Stargate.

- Added the possibility to use L+R+Start or L+R+Select to exit to the game selection menu. This has been added to use the emulator without the Center push of the joystick, not available in some WIP D-pad replacements. Thx, DaveC, for the suggestion.

- Corrected the command line support for future external frontends, thx to Zaq121.

Multi-system emulator

August 21, 2006 - Mednafen 0.6.4 Released

0.6.4:

 

* Added somewhat experimental Neo Geo Pocket(Color) emulation based off code from NeoPop, heavily modified.

* GB: Fixed frame rate when sound is disabled.

* Added →, ←, ↑, and ↓ characters to the Lynx, GB, GBA, and PC Engine directional button names used for button configuration, to match the NES button names.

* PCE: Added setting "pce.adpcmlp", default value 0, that when enabled, will cause Mednafen to apply a lowpass filter to ADPCM sound output with a rolloff frequency dependent on the current ADPCM playback frequency. This makes ADPCM voices sound less "harsh", however, the downside is that it will cause many ADPCM sound effects to sound a bit muffled.

* PCE: Moved the OpenGL screen clearing code into the FlipOpenGL() function to fix a problem with some PCE games that use multiple resolutions per frame having a partially corrupted screen when the OSD was up.

* PCE: Fixed save state loading with save states created during a CDROM data transfer.

* Fixed a bug that was causing flickering OSD remnants to remain onscreen in fullscreen mode if the OSD was drawn outside of the game screen area.

* Fixed a bug in the resizing code for save state previews that was causing save state previews for the NES, GB, GBA, and Lynx to look absolutely horrible.

* Assigned the two keys "-"(not the numpad instance) and "=" to functions "decrement selected save state slot" and "increment selected save state slot", respectively.

* Removed the checks preventing save state usage when playing NSFs, since save states may be useful with NSFs in some circumstances.

* Added a new setting "ckdelay", which controls the length of time, in milliseconds, that a button/key corresponding to a "dangerous" command like power, reset, exit, load state, etc. must be pressed before the command is executed. The default value is 0.

* Input mapping configuration is now saved after argument parsing if there is no game to be loaded, allowing a command like "mednafen -inputcfg pcegamepad1" to work properly.

* The message "Configuration finished." will now be displayed when button mapping for the selected input device is complete when using the in-game configuration process.

* PCE: Fixed a bug in the debugger involving disassembling block memory transfer instructions(effectively, the length was being fetched 1 byte too early).
