Model 2 Emulator v0.3 posted by ElSemi 22/08/2006

 

After more than 2 years without updates here is a new version of my Model 2 Emulator. The main changes are all speed related. The emu should be faster now. Also it now supports Frameskip and AutoFrameskip. This will probably be the last version of the emulator unless some Fujitsu TGP MB86234 docs appear to finish the emulation of the 2 and 2A cores.

 

* I've rewritten part of the emulator for increased speed.

* The SHARC core has also been speedup by removing unused SHARC features that weren't used by model2.

* Added frameskip and autoframeskip (with + and - in the keypad).

* Added Ski Super G and OverRev.

* Fixed topskater and virtualon control maps.

* This is probably the last version of the emulator, unless some Fujitsu TGP MB86234 docs appear

to finish the emulation of the 2 and 2A cores. Sorry, I know I still have to do the digital

sound board emulation for STCC and TopSkater but I have no free time.

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).
