[Shamus] +* Added some more developer goodies to Alpine mode. [Shamus] +* Re-added command line switches. [Shamus] +* Moved JERRY into host audio IRQ. This should make sound much smoother, though + it may run ahead of the rest of the emulator. [Shamus] +* Kludged a fix into the audio handler to set the correct frequency for audio + playback. Note that there could still be problems with this approach, as it + can be easily fooled. Thanks to Dr. Typo for the initial analysis and insight + into this bug. :-) [Shamus] +* Preliminary fixes for proper emulation of memory reads between $200000 and + $800000. [Shamus] +* Proper handling in the OP of objects with 0 IWIDTH. [Shamus] + + +Virtual Jaguar v2.0.2 GCC/Qt +---------------------------- + +* Fixed problem on OP with 24BPP bitmaps. [Shamus] +* Cosmetic GUI fixes. [Shamus] +* Switched to UAE 68000 CPU core. [Shamus] +* Fixed some RISC STORE and LOAD alignment issues. Still need to verify against + real hardware. [Shamus] +* Fixed video frame timing for both NTSC *and* PAL. [Shamus] +* Improved OP logging, added emulation of OP bug. [Shamus] +* Fixed addressing bug with UAE 68000 core. [Shamus] + + +Virtual Jaguar v2.0.1 GCC/Qt +---------------------------- + +* Fixed NTSC timings; they were hardwired to PAL rates. [Shamus] +* Fixed possible missing trailing slash on path fields input by user. [Shamus] +* Fixed exit hotkey to work on Win32. [Shamus] +* Changed PAL/NTSC switch to only work when virtual machine is powered off. + [Shamus] +* Miscellaneous documentation fixes. [Shamus] + + +Virtual Jaguar v2.0.0 GCC/Qt +---------------------------- + +* Switched GUI to Qt. And there was much rejoicing. ;-) [Shamus] +* Added detection code to fish out files from inside ZIP archives. What this + means is that now you can have other goodies inside of your ROM ZIP like + labels, box art, and overlays. See built-in help for details. [Shamus] +* Various usability improvements, too many to list here. ;-) [Shamus] +* Various compatibility improvements to the Jaguar core, too many to list + here. ;-) [Shamus] + + +Virtual Jaguar v1.1.0 GCC/SDL (r299 - Never officially released) +---------------------------------------------------------------- + +* Switched OpenGL rendering to 32 BPP. This is not only how a real Jaguar + renders graphics, but it also gives VJ a nice speed boost. ;-) [Shamus] +* Changed execution to a time-based solution so that timers and IRQs and + such can happen when they're supposed to. [Shamus] +* Fixed blitter writes so that Intensity[0-3] and Z[0-3] are written in the + correct order. [Shamus] +* Major rewrite of blitter to conform the the TOM ASIC nets. This should fix a + bunch of stuff that wasn't working correctly before. [Shamus] +* Fixed writes to 64 bit blitter registers. [Shamus] +* Refactored GUI to be more maintainable, better looking and more responsive. + [Shamus] + + +Virtual Jaguar v1.0.7 GCC/SDL +----------------------------- + +* Various fixes to make for smoother compilation on MacOS. [Adam Green] +* Fixes to filetype parsing. VJ now properly recognizes .abs, .jag, .rom, + and .j64 files--be sure to check the README for the gory details! [Shamus] +* Added a kludge to allow homebrew demos to run without a Stubulator ROM and + without crashing the emulator. [Shamus] +* Fixed a blitter intensity addition problem. This fixes the title in Hover + Strike and the road/shadows in Checkered Flag. [Shamus] +* Partially fixed a problem with the SUBC opcode in the RISC processors. This + allows Hover Strike, Phase Zero and Fight For Life to boot into their title + screens and makes them somewhat playable. [Shamus] +* Fixed a horizontal scaling problem in the OP and the off-by-one bug that it + reintroduced. This fixes the road in Atari Karts and probably a few others. + [Shamus] +* Fixed a long standing blitter bug that kept certain doors in AvP from + rendering correctly. [Shamus] +* Fixed some vertical positioning bugs in the OP. Now Checkered Flag, Alien + vs Predator and probably others now work as they should (graphically ;-) + [Caz] +* Better GUI support. Most options in the GUI work now, and more are expected + to be functional in the near future. [Shamus] +* Fixed a few more lingering blitter bugs (there are more to be found). This + fixes most of the glitches in Cybermorph and Alien vs Predator. [Shamus] +* Fixed an Object Processor scaled bitmap bug that caused incorrect + positioning of scaled bitmaps that started outside the line buffer, and + also fixed a problem that caused the OP to hang in certain situations. This + fixes Bubsy, International Sensible Soccer, and probably a few others. + [Shamus] +* Cleaned up various bits of video rendering related code. [nwagenaar] +* Added support for OpenGL textures with a depth of 16bpp, 24bpp or 32bpp. + [nwagenaar] +* Rewrote several OpenGL related rendering code concerning the new OpenGL + texture depths and texture sizes. [nwagenaar] +* Rewrote several OpenGL rendering functions concerning speed related items. + [nwagenaar] +* Several bugs resolved due to OpenGL and normal rendering code. [nwagenaar] +* Default resolution for OpenGL is now 640x480. [nwagenaar] + + +Virtual Jaguar v1.0.6 GCC/SDL +----------------------------- + +* Added support for gzipped ROM files. [Adam Green] +* Added OpenGL support. Because of this, aspect ratios in the various + graphic modes should be correct now. Thanks goes to Niels for enlightenment + in this area. :-) [Shamus] +* Moved all platform specific video code to video.cpp. This should make it + easier to add functionality to the video subsystem without having to chase + code around in places where it didn't belong. [Shamus] +* Key bindings are now customizable. [Shamus] +* VJ now uses a config file (vj.cfg) for commonly used settings. Settings in + the config file can still be overridden by command line switches. [Shamus] +* Preliminary GUI mouse support. [Shamus] +* Fixed an off-by-one bug in the Object Processor when dealing with scaled + bitmap objects. [Shamus] +* Fully virtualized screen size. What this means is that we can keep the + Jagaur screen displayed in a convenient size (320 x 240) and the graphics + that various ROMs display will now be properly centered (more or less, they + were really centered for a TV display). [Shamus] +* Border color is now displayed properly. [Shamus] +* Fully pipelined DSP core. Because of this, Wolfenstein 3D now has sound. To + use the old core, use the -nopipeline switch. [Shamus] + + +Virtual Jaguar v1.0.5 GCC/SDL +----------------------------- + +* Various fixes to the codebase so that it compiles and works properly on + Linux. :-) The makefiles are almost identical now, the only thing that's + different between them are the SYSTYPE and EXESUFFIX variables defined at + the top. [Shamus] +* Fixed a pernicious blitter bug that kept Rayman from doing proper collision + detection. [Shamus] +* Added a simple file selector so that typing in long filenames in order to + run the emulator is no longer necessary. :-) To use it, instead of + supplying a ROM name, simply put in the name of the directory where your + ROMs live. [Shamus] +* Removed all the assembly language code from the DSP, so it should be a + little less buggy now. Also, removed some brain-dead timeslice releasing + that was causing a bunch of problems with various ROMs. [Shamus] +* Added sound support! In order to hear any sound, you probably have to + start VJ with the -dspon switch. Also, unless you have a very fast computer + the sound is going to be choppy. Hopefully future optimizations will cure + this. ;-) [Shamus] +* Added GUI support. You can see the results by hitting the TAB key while the + emulator is running. ;-) [Shamus] +* Lots of cleanups to the source code including the ability to trace who + writes what to where.
