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. [Shamus] Virtual Jaguar v1.0.4 GCC/SDL - source only release --------------------------------------------------- * Lots of bugfixes. [Shamus] * Jaguar BIOS now works properly and is used by default. BIOS failure was due to a bug in the GPU (specifically in the SUBC and ADDC opcodes). To override this behavior, use the -nobios switch. [Shamus] * Rewrote the OP code--mostly because it was pissing me off. ;-) Not to mention that it was almost completely unmaintainable in its former state and was just plain wrong in its implementation in many places. Because of this, some RMW effects that were missing from AvP are present now and leftover crud in scaled bitmaps in Rayman is gone now. ;-) [Shamus] * ZIP support! Now there is no longer any need to unzip ROMs (although if you prefer to waste HD space, VJ will gladly accomodate you). The code to support this is a pretty ugly hack, but it works and there are other fish to fry at the moment. Also, ZLIB is now required to compile VJ. [Shamus] * Support for PD ROMs. Currently the only one that works at all is JagMania, though as the hardware emulation gets better more PD ROMs will begin to work. Note that you must use the -nobios switch for this to work. [Shamus] * Preliminary support for PAL Jaguar emulation. Default is NTSC. To use it, use the -pal switch. [Shamus] * Support for DSP activation. The DSP is now *off* by default, since it doesn't work properly yet. Use the -dspon switch to force the DSP on. [Shamus] * Removed all hacks that were written to support a specific ROM from the OP and GPU code (much more remains to be removed). Since the CRCs that were calculated to support these hacks were done on byte swapped ROMs, they weren't working anyway. Besides which, a hack means that you don't understand the hardware properly and/or don't know how to write the code to properly emulate the hardware. ;-) [Shamus] * Renamed the executable from the ridiculously named jag_em to the more sensibly named vj. Note that the Jag_em.cpp file has also been changed to reflect this name change. [Shamus] * Removed Aaron Giles 68K dissasembler in favor of the one included with the Musashi core. It's there, why not use it? ;-) [Shamus] * Reordered the order of A, B, and C buttons to more accurately reflect their respective positions on a real Jaguar controller. Also fixed a small bug that kept the number pad from reporting the right numbers to the emulator. :-) [Shamus] * Started to remove the !__PORT__ defintions from the source code. Since this is supposed to be a portable emulator, we won't be using any MS specific code anyway. [Shamus] * Fixed some problems with the blitter when doing clipping and bit expansion. Also fixed (reintroduced?) a bug that existed in the real blitter HW (the YADD1 bit in A2--fixes Tempest 2000). [Shamus] * Probably a bunch of other stuff that I've forgotten about. ;-) [Shamus] NOTE: Tested only on WIN32 platform! ;-) Virtual Jaguar v1.0.3 GCC/SDL - source only release --------------------------------------------------- * Converted GNU assembly in the GPU core to C code -- Rayman and Alien vs Predator work again. :-) [Shamus] * Removed closed source Starscream and replaced it with the open source Musashi core. Because of this, VJ runs a little faster now. :-) [Shamus] * Various cleanups to the source files (still lots of work to do!) [Shamus] NOTE: Tested only on WIN32 platform! 1.0.1 - 1.0.2 - Unreleased, mostly for testing/finding bugs ----------------------------------------------------------- * Lots of stuff happened, but we can't remember any of it. :-) Virtual Jaguar v1.0.0 GCC/SDL - initial source release ------------------------------------------------------ * Converted VC++ assembly to standard GNU assembly; * Fixed small bugs in SDL related items (keyboard/graphics); * Added *some* optimalisations to the graphics sources; * Added joystick support (not tested); * Added joystick port support (not tested); * Added frameskip support; Source only release. Tested on BeOS, Linux, FreeBSD and WIN32. SOUND emulation was NOT done. Need help with this one :) SDLEMU (Niels Wagenaar & Caz) - http://sdlemu.ngemu.com
