PC emulator

Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium/PentiumII/PentiumIII/Pentium4 or x86-64 CPU including optional MMX, SSEx and 3DNow! instructions.

Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows® 95/98 and Windows® NT/2000/XP or Windows Vista.

SNES emulator

2007-09-16 - bsnes v0.023 released

 

I've recently fixed a bug in bsnes that I feel is serious enough to warrant a new release, even though little else has changed.

 

I attempted to build this release with MinGW, but ran into problems with profiling and JMA support, so this release was built with Visual C++ once again.

 

Changelog:

 

* Fixed serious bug in S-SMP incw and decw instructions -- fixes sound bug in Emerald Dragon

* Added Nach's MinGW fixes -- can now be compiled with MinGW/GCC3 or MinGW/GCC4

* Fixed const char* cast warnings in GCC 4.2, thanks to [vEX] for the feedback

* Updated source to use latest libraries for libco, libui, etc.

* Added new advanced options to adjust aspect ratio correction

* Cleaned up source code a bit

Sinclair Spectrum emulator

The Latest Version of Speccy is 1.5

The latest release adds network play, support for "extended" CPC .DSK files, better scanline simulation, and an optional soft video mode. Also, it fixes many bugs with ZX Spectrum +3 and TR-DOS disk support.

 

Speccy-Symbian 1.5 also adds the NetPlay support (interoperable with Windows version) and the new "Fill&Soften" zoom mode. The source for instabilities introduced into the previous version has been removed, and the games now run at normal speed. Finally, I have added virtual keyboard support to the built-in menu, so you that you can type file names there to save files.

 

New in This Version

 

* Added network play option to Speccy-Windows and Speccy-Symbian!

* Added support for "EXTENDED CPC DISK" .DSK files (ZX Spectrum +3).

* Added -verbose bit for illegal memory accesses.

* Now polling joystick once per screen update to save on CPU cycles and network traffic.

* Fixed a bug in Z80 OUTDR/OUTD/etc. opcodes where B register was decremented after performing OUT operation. ZX Spectrum +3 disk writes work now.

* Fixed uPD765 IRQ-STATUS command to return "invalid command" when no IRQs pending. CP/M-80 now boots on Spectrum +3.

* In ZX Spectrum 128kB mode, only paging in TR-DOS from BASIC, but not from BIOS.

* Made [bACKSPACE] key generate [CSHIFT]+[0], i.e. Spectrum key combination to delete a character.

* Continued working on the DISCiPLE/+D disk drive support.

* Added new, much better, scanline simulation and video softening effects to Speccy-Windows.

* Speccy-Windows full-screen mode now runs in 640x480 resolution.

* Added "Scorpion 256kB" option to the Speccy-Windows menu.

* Added -sync/-nosync option to Speccy-MSDOS to sync screen updates to the timer (use -vsync for VBlanks).

* Added -zoom/-nozoom option to Speccy-MSDOS that will zoom Spectrum display to fill the whole screen, using image softening algorithm.

* Speccy-MSDOS now runs in 640x480x15bpp VESA screen mode when -zoom or -tv options used, otherwise it runs in 320x200x15bpp screen mode.

* Switched Speccy-MSDOS from outdated DOS4GW to more up-to-date DOS32a extender.

* Added [CONTROL]+[F8] key combination to Speccy-MSDOS to toggle display zoom on/off.

* Added Spectrum +2 and +3 ROMs to Speccy-Symbian installation.

* Fixed problem with gameplay being too fast in Speccy-Symbian.

* Fixed possible source of instabilities in the S60 open file dialog in Speccy-Symbian.

* Fixed exit via Symbian-specific menu.

* Fixed premature termination of the emulation thread when exiting Speccy-Symbian, soundtrack recording and config saving work again.

* The [C] ("Clear") key is not longer used to toggle sound in Speccy-Symbian. It acts as [bACKSPACE] instead.

Front End

New In This Version

(For M.A.M.E. version 0.119)

 

* Added additional values in the All Window Views, Prescale, and Audio Latency settings.

* Added an option to delete a game's .cfg file after gameplay. If you use the OSD in M.A.M.E. to change settings such as Brightness, Contrast, or Gamma, these changes will override those in the mame.ini. Deleting the game's .cfg file ensures that MAME Classic settings will be used everytime you play that game.

Added the main Refresh to the Status Bar.

* All Window Resolutions now gets its values from your system so you will probably find different resolutions available. In prior versions I had these hard-coded.

* Fixed an issue where not all bootleg games would be hidden if you selected Hide Bootleg Games in Options.

* Fixed some issues (I hope) involving resorting on a new column, exiting, restarting and then having the same game that was highlighted when you exited highlighted upon restarting. This is the second time I tried to fix this.

* Made some of the settings slightly more descriptive.

* Made some minor GUI changes when MAME Classic is maximized.

* Removed some erroneous values in the Frame Skipping setting.

* Removed some xml code (& for example) that would show up in the Game and Manufacturer columns with some games.

* The game lists now show multiple screen information if a game has more than one screen.

* The ROM Compare function now gives you the option to move orphan ROMs to a separate folder instead of deleting them. The folder will be created in your M.A.M.E. directory if it doesn't exist.

* Updated to accommodate M.A.M.E. 0.119.
