WARNING : this is a beta release !

What is Virtual Jaguar GCC/SDL
Virtual Jaguar is a software dedicated to emulating the Atari Jaguar hardware on
a standard PC. The software was originally developed by David Raingeard of
Potato Emulation [http://potato.emu-france.com] and was released under the GPL
on 25 June 2003.

Virtual Jaguar GCC/SDL is not only a port of the MS Visual C++/SDL sourcecode
but has also been extended and rewritten so that we can enjoy Atari Jaguar
emulation on every platform which uses the GCC compiler and that can make use of
the Simple Directmedia Layer library (SDL).

The port was done by the SDLEMU crew (http://sdlemu.ngemu.com) and especially by
Niels Wagenaar and Carwin Jones. A major portion of the rewrite was done by
James L. Hammons. You may contact us by e-mail (sdlemu()ngemu.com) or leave a
message on the SDLEMU Official Forum (see the website). Patches and bugfixes are
particularly welcome! :)
More information about SDL can be found at http://www.libsdl.org.

The AmigaOS4 port is done by HunoPPC.

- AmigaOS 4.1 update 2 with OpenGL compatible graphic card
- Jaguar Bios (jagboot.rom)
- some ROMs to play (obviously !)

- This emulator is running slow on our actual machines due to limited raw CPU
power necessary to emulate a DSP (wait for SamEP460 or X-1000 !).
- Games are playable with no DSP: exemple= Rayman; pinball fantasies; cannon
fodder etc..  
- Joystick supported
- tested on AOS4.1 update 2 (untested on AOS4.0 and AOS4.1) 
- tested on SAM ep440 667 Mhz with 64Mo, SAM Flex 800 Mhz  (with ATI Radeon 9250
128Mo) and AmigaOne XEG4 800 Mhz (with ATI Radeon 9000 pro 128Mo)
- report bugs to HunoPPC at http://www.clubevolution4.com/HunoPortSDL/

From the command line :

vj [romfile] [switches]

  -? or -help     : Display usage and switches                
  -frameskip 1-10 : Enable frameskip 1 - 10 (default: none)   
  -joystick       : Enable joystick/gamepad                   
  -joyport 0-3    : Select desired joystick port              
  -bios           : Boot cart using Jaguar BIOS ROM           
  -nobios         : Boot cart without using Jaguar BIOS ROM   
  -dsp            : Force VJ to use the DSP                   
  -nodsp          : Force VJ to run without the DSP           
  -pipeline       : Use the DSP pipelined core                
  -nopipeline     : Use the DSP non-pipelined core            
  -gl             : Use OpenGL rendering                      
  -nogl           : Use old non-OpenGL rendering              
  -fullscreen     : Enable fullscreen mode (default: windowed)
  -window         : Enable windowed mode                      
  -pal            : Force VJ to PAL mode (default: NTSC)      
  -ntsc           : Force VJ to NTSC mode
Or launch a SHELL script with icon and load ROM from the GUI

default settings in vj.cfg : OpenGL rendering with Blurry filtering, window
mode, NTSC, DSP disabled, use Joystick/Joypad

Important: reset the emulator from the menu (press ESC to access it) if you are
blocked in a game
