[Atari] BigPEmu 1.054 7/03/2023

BigPEmu - Atari Jaguar Emulator vr 1.054 7/03/2023

• Made some adjustments to the refresh rate warning logic introduced in the last version. The warning is inhibited when VSync is disabled (no, don't do it!), and an option to disable the warning has been added.

Fight For Life (1996, Mirage Media)

• VLM's CD+G support is now working.
• Refresh frequency can now be specified when selecting a display mode. (previously, the highest available was auto-selected)
• The program will now warn you if you're using a native display refresh rate which is lower than the Jaguar's current display frequency. (50Hz for PAL, 60Hz for NTSC)
• There's now a warning under the Mount Images menu telling users to avoid setting a cartridge image with a disc image if the two they were not designed to run in together. Depending on the CD BIOS (and if one is set at all), this can cause a wide variety of problems, so don't do it.
• Fixed a Blitter issue which was introduced several versions ago. The issue could result in crashes, especially when running Fight for Life.
• Fixed a problem with SUBQMOD, although there are no known instances where this fix changes any behavior in the retail library.
• Fixed more unmapped read behavior which was preventing some homebrew from running correctly.
• Fixed a Blitter negative base address issue.
• Various other minor bug fixes. Thanks to all of the people who submitted bug reports through the web site!

BigPEmu - Atari Jaguar Emulator vr 1.052 13/02/2022

• Added a "Sample Scale" option for the System Audio Disc.
• I heard you like minor timing fixes, so I made some minor timing fixes to the minor timing fixes.

BigPEmu vr. 1.051

• Minor timing fixes.

BigPEmu vr. 1.05

• Jaguar CD support! This encompasses a whole bunch of new functionality. Thank you to Mycah Mattox for donating the Jaguar CD hardware, this hardware was essential for my research.
• Added -nodevicechange and -fulldevrefresh as command line options.
• Added -forceloadaddr and -forcerunaddr as command line options.
• Added -setcfgprop and -setcfgpropcat as command line options.
• Added -audiocapindex as a command line option, can be used when launching *VirtualDisc_SystemAudio as the ROM image via command line.
• Added -physdevindex as a command line option, can be used when launching *VirtualDisc_SystemPath as the ROM image via command line.
• Added another DirectInput workaround which may help prevent stuck analog controls on some machines. Thanks to neurocrash for spending a lot of time running tests for me on a machine where this was an issue!
• Fixed a problem with depth writes in 32-bit mode, thanks to 42Bastian for providing a test case.
• Fixed an issue with word strobes not being correctly scheduled until a write to SMODE/SCLK. (only relevant when running with no boot ROM set)
• Fixed a timing problem with EEPROM reads.
•  Fixed scaling on monitors with a non-standard DPI.
• When adding a new individual input trigger in the binds menu, the prompt mode now defaults to "specify hold and button" instead of just "specify button". (in line with binding all inputs via "Set All")
• Lots of additional core emulation fixes which came along with CD support.
• Implemented some intentional redundancy in the OpenGL video plugin's state management, to guard against things like Discord's video capture poking around in the context without cleaning up after itself.
• With CD support wrapped up, I'm taking a short hiatus! I need to recouperate, generate some income, and prepare for the next phase of my cancer treatment. Please don't inundate me with fix/feature requests via e-mail/Discord/etc. during this time. Instead, I ask that you use the less invasive Bug Report form on the web site. Thank you for your consideration!

BigPEmu Version 1.04 12/27/2022

Zero 5 (Telegames,Inc., 1997)

• Added -devmode as a command line option. Don't get too excited, this isn't opening up full developer build functionality just yet. (and the option will be auto-enabled in proper developer builds) It does enable a developer menu, though, and some additional developer-oriented key binds.
• Added a "Local EEPROM" option to the new developer menu at CJ Reboot's request.
• Added a "Save Window Position" option to the new developer menu at CJ Reboot's request.
• Added an "Always on Top" option to the new developer menu at CJ Reboot's request.
• Added a new set of developer input binds, which are only accessible when using -devmode. Most of these new binds were added at 42Bastian's request.
• Now picking through individual device/state changes instead of just refreshing all input devices when a DEVNODES_CHANGED-type message is received. Fixes input disruptions on machines where something is causing DEVNODES_CHANGED spam.
• Fixed a problem when recording a movie with the "Increment on Save" setting enabled. Thanks to Doug Engel for finding this bug!
• Fixed a crash when entering the Zero 5 sound options screen.
• Every issue which was submitted through the Bug Report form on the website has now been resolved. Thanks to everyone who contributed! If you submitted something which still isn't resolved in this build, let me know.

BigPEmu Version 1.03 12/21/2022

• Fix for some emulator state overrides not sticking when launching software via command line.

BigPEmu Version 1.01 12/05/2022

• Added interlaced display support. This is definitely not working the way it works on hardware, but it addresses the test case that Doug Engel was kind enough to send over.
• Added a "force horizontal overscan" option.
• Added an option to force Jaguar GD emulation, which enables bank switching even in ROM images smaller than 6MB.
• Added -localdata as a command line option.
• Changed the first visible column default. (applies to both NTSC and PAL)
• Fix for a 16-bit DAC write bug. (fixes one-sided audio in Super Burnout)
• Fix for a problem on the Blitter's SRCSHADE data path. Thanks to Doug Engel for reporting the BattleSphere bug which led to this fix.
• Fix for OP sometimes running over HDE, thanks to CJ Reboot for reporting the associated bug.
• Fix for input bindings sometimes not being picked up from per-game config files. This bug could also potentially cause game-specific bindings to "stick" and infect the global config bindings.

BigPEmu Version 1.01 12/05/2022

Hover Strike (AtariCorporation, 1995). Natywne screenshoty są pozbawione wszelkich wodotrysków, ale wielki plus za możliwość mapowania robienia zrzutów na padzie lub klawiaturze.

• Added variable-sized EEPROM support, thanks to Reboot for providing some test cases. 512 byte and 2KB EEPROM settings are picked up from the MRQ file if it exists, otherwise any number of EEPROM address bits can be specified via the -eeprombits command line option.
• Added JaguarGD bank switching support.
• Fix for exception-handled M68K reads in unmapped address space.
• Fix for Blitter not correctly wrapping cyan/red on add when ADDDSEL is set, thanks to ScatoLOGIC for reporting the BattleSphere bug which led to this fix.
• Fix for Blitter not starting on the correct bit when block width is less than pixel size and phrase mode is not enabled, thanks to ScatoLOGIC for reporting the BattleSphere bug which led to this fix.
• Going in for a major surgery tomorrow (2022/12/06), so expect that I'll be mostly unavailable and that there won't be any emulator updates for at least a couple of weeks.

BigPEmu Version 1.00 12/01/2022

• First public release!

Checkered Flag (AtariCorporation, 1994). HDR plus HLSL, trzeba popracować trochę nad ustawieniami.

BigPemu GUi - dużo opcji i bardzo przejrzyste menu

Defender 2000 (AtariCorporation, Feb, 1996)

Flashback: The Quest for Identity (a.k.a. Flashback) (U.S.GoldLtd., Jun, 1995)

Wolfstein 3D (1994, Atari, ID Software)

BigPEmu - Atari Jaguar Emulator vr 1.092 6/10/2023

• Added an optional rewind feature, see the new "Rewind Count" setting as well as the new "Rewind" key bind.
• Added an optional network rewind feature, see the "Network Rewind" setting under the Network menu. Rewinds the state and immediately runs the emulator back to the current frame when an input discrepancy occurs. Requires a powerful machine to avoid hitches. (emulating Jaguar frames isn't cheap)
• Added analog/mouselook support to the AvP script.
• Added a new Wolfenstein 3D script with analog/mouselook support. (includes always-strafe and always-run options)
• Added a new Iron Soldier script with analog/mouselook support.
• Minor performance improvements.

International Sensible Soccer (1995, Sensible Software). I dużo deformacji ekranu.

BigPEmu - Atari Jaguar Emulator vr 1.091 22/09/2023

• AvP multiplayer fixes.
  • Fixed some player projectile weapons not colliding with other players.
  • Fixed a bunch of AI projectiles not being correctly synchronized.
  • Fixed an issue which would sometimes cause AI to stop attacking.
  • If a human player teleports into a new level without a weapon, the shotgun is now automatically granted.
  • Fixed a bug which could sometimes cause bigpemu_net_behind to misreport.
    • New script functions: bigpemu_net_hostmsg, bigpemu_net_disconnect, and bigpemu_net_lastclient.

BigPEmu - Atari Jaguar Emulator vr 1.09 17/09/2023

• New "State Sync" network device type, synchronizes system state across the network. This allows local 2-player games to be played over Internet/LAN connections.
  • Very simple implementation that just stalls out if input doesn't arrive in time. State Sync Delay option adjusts the anticipated latency window. If you run into timing issues, the host can manually kick everyone back together by loading a state.
  • State Sync Remap can be used to remap the first local input device to any other input device. Also allows overlapping controls. (e.g. two peers both affecting the first input device)
  • Works with any number of clients, with clients above the supported input device count being treated as spectators.
• New "Script" network device type, allows scripts to implement custom network/socket handlers. Includes automatic delta compression and some other niceties.
• A new script adds multiplayer to AvP!
  • Implements networking from scratch using the aforementioned socket interface, and works with the unmodified retail ROM image.
  • Proper client-server architecture, up to 32 players can drop in at any time during gameplay. (in theory)
  • Generally handles the fundamentals, but expect plenty of limitations, bugs, and odd behavior. This game wasn't designed to support multiplayer, and I've left a few threads hanging under the guise of "shippable."
  • Enemies can correctly change off between player targets.
  • I hope this serves as another demonstration of the sort of madness which can be accomplished with the scripting system, and I'd love to see others give this sort of treatment to more titles.
• Lots of new scripting/VM functionality.
  • UI event callbacks for custom rendering over/under the rest of the UI.
  • New UI rendering functions for various primitives and text.
  • Input functions to allow querying input states across all native devices.
  • Scripts can now load and render/play texture and sound resources.
  • New native-backed 4x4 matrix/transform operations.
  • Script can now get a list of ROM from from the current ROM directory, and load images in that directory.
  • Scripted polygon texture references now have the option of pointing to native texture resources. Could be useful for something like a high-res texture replacement script.
• Fixed a floating point comparison bug in the VM interpreter.
• VM modules are now loaded automatically if a .bigpcvm file is present with the same name as the ROM image being loaded, similar to other image-specific resources. This allows Jaguar software to be distributed alongside emulator-specific script enhancements.

BigPEmu - Atari Jaguar Emulator vr 1.08 26/08/2023

• JagLink support is here!
  • Max player count is supported in AirCars and BattleSphere, with the potential for any number of emulated Jaguars to be networked together.
  • Special splitscreen functionality has been added.
  • Works over Internet/LAN or locally via loopback.
    • Don't expect anything to be playable or stable over the Internet unless you've got LAN-like latency and no packet loss.
  • When the central host loads a saved state, it's automatically propagated to all clients.
  • Here's a video which goes over all of the network features and demonstrates a splitscreen setup: https://youtu.be/b2e7Vl4aLps
• Added -cfgpath and -cfgpathabs command line options. This overrides the default config path, useful for splitscreen instances.
• Added -windowx and -windowy command line options. Useful for tiling out instances for splitscreen play.
• Added a -noborder command line option. Removes the border from the window in windowed mode, best used with -windowx, -windowy, -forcewidth, and -forceheight.
•  Added an -alwaystop command line option. Keeps the window always-on-top, also useful for splitscreen mode.
• Added -netlisten, -netconnect, -netport, -netmax, -netloaddelay, -netpcldelay, and -nettcp command line options.
• Bumped the debugger protocol version, make sure you update to the latest Noesis if you're using the developer build.

BigPEmu - Atari Jaguar Emulator vr 1.071 08/08/2023

• Fixed a bug which was causing the VR Swap Eyes setting to be incorrectly tied to other settings. This probably explains reports from some users of being "cross-eyed" by default.
• Added stereoscopic rendering support for the GPU list variant used by the MC3D stage 1-3 boss.

BigPEmu - Atari Jaguar Emulator vr 1.07 05/08/2023

•  Jaguar VR support is here, with head tracking and stereoscopic rendering.
  • A new Head Tracker input device type has been added, along with some options for converting analog inputs to tracker angles.
  • Stereoscopic rendering is fully implemented, and integrated into the scripting system.
  • Check out all the new settings in the Video/VR menu.
  • The scripting system has the potential to add Head Tracker support and stereoscopic rendering to any Jaguar title, so more Jaguar VR games may be coming!
  • This video demonstrates and explains some of the new VR functionality: https://youtu.be/BAJjzlrsbis
• Added an OpenVR plugin to support the new Jaguar VR implementation.
• A new script is included to implement stereoscopic rendering and enable Head Tracker support in the final/retail version of Missile Command 3D.
  • To map the head tracking through any analog input with the script enabled: set the second input device type to "Head Tracker", and bind the second device's analog inputs to whatever pleases you.
  • To enable stereoscopic rendering with the script enabled: go to Script Settings in the menu and enable the stereoscopic rendering option. Stereo-capable scenes will be rendered using the emulator's selected VR/anaglyph 3D settings.
  • When VR is enabled (via the Video/VR settings) and successfully initialized, if a compatible headset is present, its orientation will automatically feed the Head Tracker input.
  • Stereoscopic rendering was never actually implemented in MC3D, this is a brand new software feature designed to fully realize the potential of Jaguar VR.
• Fixed a Blitter issue with DCOMPEN in phrase mode. (introduced in the Patreon-exclusive 1.061 build)
• Lots of changes/additions for developer mode, and separate debugger-enabled builds are now available from the official web site. Check the ReadMeDev.txt file in the debugger-enabled build distribution for more information. (introduced in the Patreon-exclusive 1.061 build)

Aliens vs Predator (1994, Atari)

BigPEmu - Atari Jaguar Emulator vr 1.06 25/05/2023

• New scripting system. In developer mode, scripts are auto-recompiled on startup. Developer options are also available to automatically detect script changes while the application is running. Compiled scripts must be enabled through a new Script Modules feature.
• A new script is included which allows Cybermorph to render polygons/textures at the native resolution.
• An option for adjusting MSAA has been added to the video settings. This is only relevant to things which use the native depth buffer, like the new Cybermorph script.
•  A new script is included which allows uncapping the framerate in Alien vs. Predator.
•  A new script is included which fixes flickering in the Brett Hull Hockey prototype.
• A simplified CRT library along with a whole bunch of BigPEmu-specific API functionality is included in the scripting system via the Scripts/bigpcrt library.
• Basic native DLL (CDECL) call functionality has been implemented in the scripting API, so that others can take the initiative to start implementing things like RetroAchievements as desired.
• Added native mouse input support. (must be enabled in the input settings) Mouse movement and buttons can be bound to analog, rotary, and digital inputs interchangeably.
• Some more work on debugger-enabled builds has been done behind the scenes, but this shouldn't affect anything user-facing just yet.
•  Even more terrible secrets have been added.
• Made sure native rendering works even with a Screen Effect active. However, this isn't generally a recommended combination, as the effect will be sourcing from a native-resolution buffer instead of a Jaguar-resolution buffer. (post-Patreon build addition)
•  Added a -conout command line option. Under Windows, this spawns a console and directs log output here instead of to a file. (post-Patreon build addition)
•  The breadth of functionality encompassed by the scripting system is too vast to cover here, so I've made a video to highlight some of the features and explain how the existing scripts work: https://youtu.be/y4gXxSmLOg4
• Please help me out with support on social media and Patreon! Things have continued to be rough on the health front lately, and I've found it's getting harder to use Twitter to reach my actual target audience, so I'm depending more on organic word of mouth to spread project news and hopefully bring in support.
