Stella, an open-source multi-platform Atari 2600 VCS emulator has been updated today. Here's a list of what's new in v3.5.5:
- Due to changes in the debugger, old state files will not work with this release.
- Fixed bug in sound restructuring introduced in the last release; in some cases, there could be some sound 'crackling' when starting a ROM after at least one ROM had already been loaded.
- Several significant improvements to the debugger I/O tab:
- added controller input widgets for many of the built-in controllers, allowing to control joysticks, paddles, etc from within the debugger.
- added ability to modify the SWCHB/SWBCNT port B registers.
- added ability to view TIA INPTx and VBLANK latch/dump bits.
- Reworked 'mcontrol' argument, and added ability to map the mouse axes separately for paddles 0-3 or driving controllers 0-1. In such modes, the left mouse button is tied to the x-axis, and the right button is tied to the y-axis.
- Mouse 'specific-axis' mode is now saved per-ROM, meaning that each ROM can have separate settings. For example, this allows one ROM to use paddles 0 and 1, while another can use paddles 0 and 2, etc.
- The key-combo for switching the mouse between controller modes is now 'Control-0' (Control-1,2,3 have been removed). This switches between all possible modes for the current virtual controllers.
- Fixed bug in 'Fixed Debug Colors' mode; under certain circumstances, playfield graphics could be coloured as being player graphics.
- Fixed bug in PAL color-loss setting in Video Settings; changing the settings wouldn't take effect until the ROM was reloaded.
- Fixed bugs with cheatcode handling; loading a ROM with a cheat disabled would sometimes trash the emulation. More work is required in this area, including the ability to create more advanced types of cheats.
- Updated ROM properties database for all Sega Genesis controller compatible ROMs. Also, the mouse can now emulate a Genesis controller, with the left/right buttons mapped to buttons B and C, respectively.
- Added 'FA2' bankswitch scheme, thanks to code from Chris D. Walton. This scheme will be used in an upcoming 'Star Castle' ROM.
- Updated internal ROM properties database to ROM-Hunter version 7 (thanks go to RomHunter for his tireless research in this area).
- Added several PERL tools to help in automation of analyzing RomHunter ROM set releases.
- Fixed compile issues in Irix when using the default compiler instead of gcc. Thanks go to Rainer M. Canavan for this code.
- Updated included PNG library to latest stable version.

Stella, a multi-platform Atari 2600 VCS emulator has been updated recently. Here's a list of changes in this release:
- Stella is now DonationWare! Please see the DonationWare link on the main webpage for more information.
- Added several improvements to the joystick management code. Joystick event mapping is now saved per device, meaning that if you map events to a certain joystick device, remove the device and then later insert it again, Stella will remember the original mapping.
- The total number of joysticks present and their associated properties (number of axes, buttons and hats) is now dynamic. That is, there's no longer a hard-coded limit on the number of joysticks that Stella can use, or the number of buttons, etc that it contains. This fixes a serious bug with PS3 controllers with 27 buttons, whereby adding a mapping for joystick 0 would inadvertantly change settings for joystick 1, and could potentially lead to a program crash.
- Added 'mcontrol' commandline argument, which can specify to use each mouse axis as a separate paddle. The old (and default) behaviour can be activated by setting this argument to 'auto'. Related to this, removed redundant 'usemouse' argument.
- Huge restructuring of the OpenGL code, making it compatible with OpenGL 2.x+ features (such as vertex buffer objects), while at the same time keeping compatibility with OpenGL 1.5 / OpenGL ES. Because of the required changes, TV effects were removed (they will be added again for the next release).
- Improvements to audio handling, particularly for certain cases of Windows, ATI video cards, and OpenGL mode. The sound device is now opened only once when Stella starts, and is paused between loading different ROMs. This fixes a problem whereby sound could possibly not be functional after loading the first ROM. Related to this, removed the 'audiofirst' commandline argument as it's now redundant.
- Fixed bug with displaying the ROM launcher in Windows XP; the initial load was sometimes taking up to 30 seconds to complete.
- Added logging facility, whereby the output of the application is available within Stella itself. This can still be printed to the console, or also saved to a file. Add the 'loglevel' and 'logtoconsole' commandline arguments which control these settings, and removed the 'showinfo' argument as it's now redundant.
- Updated DPC+ bankswitching scheme to latest code provided by SpiceWare.
- Added MAMCR handling to the Thumb ARM emulation code. Note that MAMCR isn't actually emulated, it is just ignored for now. This fixes a bug whereby accessing MAMCR would crash the ARM emulation.
- Added 'thumb.trapfatal' commandline argument, which causes the Thumb ARM emulation to either trap on a fatal error (throw an exception to the debugger and exit emulation) or simply log the error and continue. This should normally always be enabled, but can be disabled by developers for testing reasons.
- Updated default snapshot directory to be much saner and easier to find. For most systems, it now defaults to the users 'Desktop'. Note that the commandline argument has changed to 'snapdir'.
- The debugger 'print' command now indicates "special" addresses if they are read-only ®, write-only (W) or read-write (R/W).
- Fixed a bug where scrolling the mouse-wheel in certain debugger UI items would cause the program to crash; scrolling now works as expected.
- Fixed minor display issue in the debugger RAM area; some addresses were being displayed as '...'.
- Fixed compile issues in the latest versions of Ubuntu and Debian, and fixed UNIX desktop file so that Stella will launch with a ROM when selected from its icon. Thanks go to Stephen Kitt for this code.
- Updated included PNG library to latest stable version.
- Updated the credits list in the documentation, listing people that have donated hardware to the Stella team.

Ootake, a Turbo Grafx 16 emulator for Windows has been updated today. Here's a list of changes in this release:
- The performance of these days' PC improved. So the default setting was made high-definition setting.
- At the menu space of "Save State" and "Load State", "the elapsed time from the game start" is indicated.
- If the save file is started with the old version (before v1.14), the elapsed time isn't indicated.
- If the game is reset by [F1] key, it's possible to reset the elapsed time. Or, after state file of the old version is read, if you carry out the "File->Set Resume" menu, the elapsed time is reset.
- A severe indication restriction mode of Sprite (at width 336 pixel mode) was mounted.
- When the check is put at "CPU->Perform SpriteLimit" menu, it's effective. In "R-TYPE Complete CD", a flicker of sprite (character) becomes the same motion (intense flicker more the "R-Type I" of Hu-CARD) as a real machine.
- The speed and timing were brought close to the movement of a real machine. In "Metal Angel", the problem which cannot start a game (from v2.58) was solved.
- Additionally, a detailed part has been improved and corrected.
- The execution file for "Windows 98/Me" was opened to the public. The operation test is not done. Please see "Readme98.txt" in the ZIP file about details and notes, etc. http://www.ouma.jp/f...ke263-for98.zip

Ootake, a Turbo Grafx 16 emulator for Windows has been updated today. Here's a list of changes in this release:
- The maximum of the volume adjustment (PageUp,PageDown and FunctionButton+UpDown) was changed to 120 from 100.
- Only the time of a play on Hu-Card game is effective for 101-120. At playing CD-ROM game, 101-120 is the same volume as 100. (To stop saturation of sound)
- When a check is put on the "File->Set Resume" menu, preservation and restoration of volume setting can be done.
- Processing of ADPCM sound was improved. The sound quality improved. In the visual scene of "Jantei Monogatari 2", the problem that sound was difficult to catch improved.
- A volume balance of "wave memory sampling sound" was readjusted. I think The quality of the voice (mainly Hu-Card game) was improved.
- A volume balance of the whole sound was readjusted. I think it approached a real machine.
- With some PC environment, at full-screen of 640x480 (Direct 3D), the problem that the screen upper part flickered was corrected.
- With some PC environment, when overscan territory is indicated at 640x480(Direct3D), there is a possibility which flickers. In that case, choose the "Setting->Screen->DirectDraw(Old)" menu.
- The speed and timing were brought close to the movement of a real machine. In the visual scene of "Jantei Monogatari 2", a problem that a screen was in disorder was settled.
- Additionally, a detailed part has been improved and corrected.
- The execution file for "Windows 98/Me" was opened to the public. The operation test is not done. Please see "Readme98.txt" in the ZIP file about details and notes, etc. http://www.ouma.jp/f...ke262-for98.zip
