1 Virtual Jaguar v1.0.7 GCC/SDL
2 -----------------------------
4 * Better GUI support. Most options in the GUI work now, and more are expected
5 to be functional in the near future. [Shamus]
6 * Fixed a few lingering blitter bugs (there are more to be found). This fixes
7 a few glitches in Cybermorph and Alien vs Predator. [Shamus]
8 * Fixed an Object Processor scaled bitmap bug that caused incorrect
9 positioning of scaled bitmaps that started outside the line buffer, and
10 also fixed a problem that caused the OP to hang in certain situations. This
11 fixes Bubsy, International Sensible Soccer, and probably a few others.
15 Virtual Jaguar v1.0.6 GCC/SDL
16 -----------------------------
19 * Added support for gzipped ROM files. [Adam Green]
20 * Added OpenGL support. Because of this, aspect ratios in the various
21 graphic modes should be correct now. Thanks goes to Niels for enlightenment
22 in this area. :-) [Shamus]
23 * Moved all platform specific video code to video.cpp. This should make it
24 easier to add functionality to the video subsystem without having to chase
25 code around in places where it didn't belong. [Shamus]
26 * Key bindings are now customizable. [Shamus]
27 * VJ now uses a config file (vj.cfg) for commonly used settings. Settings in
28 the config file can still be overridden by command line switches. [Shamus]
29 * Preliminary GUI mouse support. [Shamus]
30 * Fixed an off-by-one bug in the Object Processor when dealing with scaled
31 bitmap objects. [Shamus]
32 * Fully virtualized screen size. What this means is that we can keep the
33 Jagaur screen displayed in a convenient size (320 x 240) and the graphics
34 that various ROMs display will now be properly centered (more or less, they
35 were really centered for a TV display). [Shamus]
36 * Border color is now displayed properly. [Shamus]
37 * Fully pipelined DSP core. Because of this, Wolfenstein 3D now has sound. To
38 use the old core, use the -nopipeline switch. [Shamus]
41 Virtual Jaguar v1.0.5 GCC/SDL
42 -----------------------------
44 * Various fixes to the codebase so that it compiles and works properly on
45 Linux. :-) The makefiles are almost identical now, the only thing that's
46 different between them are the SYSTYPE and EXESUFFIX variables defined at
48 * Fixed a pernicious blitter bug that kept Rayman from doing proper collision
50 * Added a simple file selector so that typing in long filenames in order to
51 run the emulator is no longer necessary. :-) To use it, instead of
52 supplying a ROM name, simple put in the name of the directory where your
54 * Removed all the assembly language code from the DSP, so it should be a
55 little less buggy now. Also, removed some brain-dead timeslice releasing
56 that was causing a bunch of problems with various ROMs. [Shamus]
57 * Added sound support! In order to hear any sound, you probably have to
58 start VJ with the -dspon switch. Also, unless you have a very fast computer
59 the sound is going to be choppy. Hopefully future optimizations will cure
61 * Added GUI support. You can see the results by hitting the TAB key while the
62 emulator is running. ;-) [Shamus]
63 * Lots of cleanups to the source code including the ability to trace who
64 writes what to where. [Shamus]
67 Virtual Jaguar v1.0.4 GCC/SDL - source only release
68 ---------------------------------------------------
70 * Lots of bugfixes. [Shamus]
71 * Jaguar BIOS now works properly and is used by default. BIOS failure was
72 due to a bug in the GPU (specifically in the SUBC and ADDC opcodes). To
73 override this behavior, use the -nobios switch. [Shamus]
74 * Rewrote the OP code--mostly because it was pissing me off. ;-) Not
75 to mention that it was almost completely unmaintainable in its former
76 state and was just plain wrong in its implementation in many places.
77 Because of this, some RMW effects that were missing from AvP are present
78 now and leftover crud in scaled bitmaps in Rayman is gone now. ;-) [Shamus]
79 * ZIP support! Now there is no longer any need to unzip ROMs (although if
80 you prefer to waste HD space, VJ will gladly accomodate you). The code to
81 support this is a pretty ugly hack, but it works and there are other fish
82 to fry at the moment. Also, ZLIB is now required to compile VJ. [Shamus]
83 * Support for PD ROMs. Currently the only one that works at all is JagMania,
84 though as the hardware emulation gets better more PD ROMs will begin to
85 work. Note that you must use the -nobios switch for this to work. [Shamus]
86 * Preliminary support for PAL Jaguar emulation. Default is NTSC. To use it,
87 use the -pal switch. [Shamus]
88 * Support for DSP activation. The DSP is now *off* by default, since it
89 doesn't work properly yet. Use the -dspon switch to force the DSP on.
91 * Removed all hacks that were written to support a specific ROM from the OP
92 and GPU code (much more remains to be removed). Since the CRCs that were
93 calculated to support these hacks were done on byte swapped ROMs, they
94 weren't working anyway. Besides which, a hack means that you don't
95 understand the hardware properly and/or don't know how to write the code to
96 properly emulate the hardware. ;-) [Shamus]
97 * Renamed the executable from the ridiculously named jag_em to the more
98 sensibly named vj. Note that the Jag_em.cpp file has also been changed to
99 reflect this name change. [Shamus]
100 * Removed Aaron Giles 68K dissasembler in favor of the one included with the
101 Musashi core. It's there, why not use it? ;-) [Shamus]
102 * Reordered the order of A, B, and C buttons to more accurately reflect their
103 respective positions on a real Jaguar controller. Also fixed a small bug that
104 kept the number pad from reporting the right numbers to the emulator. :-)
106 * Started to remove the !__PORT__ defintions from the source code. Since this
107 is supposed to be a portable emulator, we won't be using any MS specific
108 code anyway. [Shamus]
109 * Fixed some problems with the blitter when doing clipping and bit expansion.
110 Also fixed (reintroduced?) a bug that existed in the real blitter HW (the
111 YADD1 bit in A2--fixes Tempest 2000). [Shamus]
112 * Probably a bunch of other stuff that I've forgotten about. ;-) [Shamus]
114 NOTE: Tested only on WIN32 platform! ;-)
117 Virtual Jaguar v1.0.3 GCC/SDL - source only release
118 ---------------------------------------------------
120 * Converted GNU assembly in the GPU core to C code -- Rayman and
121 Alien vs Predator work again. :-) [Shamus]
122 * Removed closed source Starscream and replaced it with the open source
123 Musashi core. Because of this, VJ runs a little faster now. :-) [Shamus]
124 * Various cleanups to the source files (still lots of work to do!) [Shamus]
126 NOTE: Tested only on WIN32 platform!
129 1.0.1 - 1.0.2 - Unreleased, mostly for testing/finding bugs
130 -----------------------------------------------------------
132 * Lots of stuff happened, but we can't remember any of it. :-)
135 Virtual Jaguar v1.0.0 GCC/SDL - initial source release
136 ------------------------------------------------------
138 * Converted VC++ assembly to standard GNU assembly;
139 * Fixed small bugs in SDL related items (keyboard/graphics);
140 * Added *some* optimalisations to the graphics sources;
141 * Added joystick support (not tested);
142 * Added joystick port support (not tested);
143 * Added frameskip support;
145 Source only release. Tested on BeOS, Linux, FreeBSD and WIN32.
146 SOUND emulation was NOT done. Need help with this one :)
