1 Virtual Jaguar v1.0.5 GCC/SDL
2 -----------------------------
4 * Various fixes to the codebase so that it compiles and works properly on
5 Linux. :-) The makefiles are almost identical now, the only thing that's
6 different between them are the SYSTYPE and EXESUFFIX variables defined at
8 * Fixed a pernicious blitter bug that kept Rayman from doing proper collision
10 * Added a simple file selector so that typing in long filenames in order to
11 run the emulator is no longer necessary. :-) To use it, instead of
12 supplying a ROM name, simple put in the name of the directory where your
14 * Removed all the assembly language code from the DSP, so it should be a
15 little less buggy now. Also, removed some brain-dead timeslice releasing
16 that was causing a bunch of problems with various ROMs. [Shamus]
17 * Added sound support! In order to hear any sound, you probably have to
18 start VJ with the -dspon switch. Also, unless you have a very fast computer
19 the sound is going to be choppy. Hopefully future optimizations will cure
21 * Added GUI support. You can see the results by hitting the TAB key while the
22 emulator is running. ;-) [Shamus]
23 * Lots of cleanups to the source code including the ability to trace who
24 writes what to where. [Shamus]
27 Virtual Jaguar v1.0.4 GCC/SDL - source only release
28 ---------------------------------------------------
30 * Lots of bugfixes. [Shamus]
31 * Jaguar BIOS now works properly and is used by default. BIOS failure was
32 due to a bug in the GPU (specifically in the SUBC and ADDC opcodes). To
33 override this behavior, use the -nobios switch. [Shamus]
34 * Rewrote the OP code--mostly because it was pissing me off. ;-) Not
35 to mention that it was almost completely unmaintainable in its former
36 state and was just plain wrong in its implementation in many places.
37 Because of this, some RMW effects that were missing from AvP are present
38 now and leftover crud in scaled bitmaps in Rayman is gone now. ;-) [Shamus]
39 * ZIP support! Now there is no longer any need to unzip ROMs (although if
40 you prefer to waste HD space, VJ will gladly accomodate you). The code to
41 support this is a pretty ugly hack, but it works and there are other fish
42 to fry at the moment. Also, ZLIB is now required to compile VJ. [Shamus]
43 * Support for PD ROMs. Currently the only one that works at all is JagMania,
44 though as the hardware emulation gets better more PD ROMs will begin to
45 work. Note that you must use the -nobios switch for this to work. [Shamus]
46 * Preliminary support for PAL Jaguar emulation. Default is NTSC. To use it,
47 use the -pal switch. [Shamus]
48 * Support for DSP activation. The DSP is now *off* by default, since it
49 doesn't work properly yet. Use the -dspon switch to force the DSP on.
51 * Removed all hacks that were written to support a specific ROM from the OP
52 and GPU code (much more remains to be removed). Since the CRCs that were
53 calculated to support these hacks were done on byte swapped ROMs, they
54 weren't working anyway. Besides which, a hack means that you don't
55 understand the hardware properly and/or don't know how to write the code to
56 properly emulate the hardware. ;-) [Shamus]
57 * Renamed the executable from the ridiculously named jag_em to the more
58 sensibly named vj. Note that the Jag_em.cpp file has also been changed to
59 reflect this name change. [Shamus]
60 * Removed Aaron Giles 68K dissasembler in favor of the one included with the
61 Musashi core. It's there, why not use it? ;-) [Shamus]
62 * Reordered the order of A, B, and C buttons to more accurately reflect their
63 respective positions on a real Jaguar controller. Also fixed a small bug that
64 kept the number pad from reporting the right numbers to the emulator. :-)
66 * Started to remove the !__PORT__ defintions from the source code. Since this
67 is supposed to be a portable emulator, we won't be using any MS specific
69 * Fixed some problems with the blitter when doing clipping and bit expansion.
70 Also fixed (reintroduced?) a bug that existed in the real blitter HW (the
71 YADD1 bit in A2--fixes Tempest 2000). [Shamus]
72 * Probably a bunch of other stuff that I've forgotten about. ;-) [Shamus]
74 NOTE: Tested only on WIN32 platform! ;-)
77 Virtual Jaguar v1.0.3 GCC/SDL - source only release
78 ---------------------------------------------------
80 * Converted GNU assembly in the GPU core to C code -- Rayman and
81 Alien vs Predator work again. :-) [Shamus]
82 * Removed closed source Starscream and replaced it with the open source
83 Musashi core. Because of this, VJ runs a little faster now. :-) [Shamus]
84 * Various cleanups to the source files (still lots of work to do!) [Shamus]
86 NOTE: Tested only on WIN32 platform!
89 1.0.1 - 1.0.2 - Unreleased, mostly for testing/finding bugs
90 -----------------------------------------------------------
92 * Lots of stuff happened, but we can't remember any of it. :-)
95 Virtual Jaguar v1.0.0 GCC/SDL - initial source release
96 ------------------------------------------------------
98 * Converted VC++ assembly to standard GNU assembly;
99 * Fixed small bugs in SDL related items (keyboard/graphics);
100 * Added *some* optimalisations to the graphics sources;
101 * Added joystick support (not tested);
102 * Added joystick port support (not tested);
103 * Added frameskip support;
105 Source only release. Tested on BeOS, Linux, FreeBSD and WIN32.
106 SOUND emulation was NOT done. Need help with this one :)
