1) Full-screen playing, even in HD modes: Now you can play at full-screen, both with 480, 720p or 1080i. This has been achieved by replacing all the SDL code related to video, with Xbox native Direct3D code.

2) Noticeable speed improvement: Besides the full-screen support, the native Direct3D code also brang a speed improvement. This makes that some games that were hardly playable in the last version, can be played in this one at good speed (for example Kasumi Ninja or Zool 2). Besides, many games that need overclocked sound/GPU, will have better sound and less graphical glitches now, because the overclocking factor now is much lower.

3) Improved compatibility: There are new playable games that didn't work (or were unplayable) in previous versions, like Soccer Kid, Protector Special Edition, Zero 5, Worms, Evolution - Dino Dudes, Kasumi Ninja...

4) Better savegame management: In the past versions, there was an annoying bug that caused that, if you didn't exit from the game in a proper way (START+BACK) you lost all the saved games related to that rom!! This bug has been fixed with a better savegame management. Now, if you exit bad, you will only loose the current game, but all the previous saved progress will be kept. So, you will never loose your saved games again (time to beat Rayman now?).

1) Now you can have a lot of games in your "roms" folder (the previous version had a bug when you had more than 50-60 roms). And these roms can have moderately long names if you want. Anyways, remember that the files must have a "normal" name if you want that the emulator is able to recommend the best settings for that game. For example, if you have the game Rayman you can name it like "Rayman.zip" or "Rayman (Ubisoft).j64" or whatever you want that begins with "Raym"... but don't rename it like "My favorite game.zip", because the emulator will not know that it is Rayman!

2) Preliminary screenshots support. The emulator search for screenshots with the same name of the rom (but extension "jpg") in the "media/artwork/action" folder (like in the Xtras) and if it exists, it will show it when the game is selected in the menu. This package contains some screenshots of some of the most famous games, but you must rename your roms like them if you want them to work. For example, if the screenshot is "Kasumi Ninja.jpg", rename your rom as "Kasumi Ninja.zip".

3) Background music

4) Better joystick management

If you have an HD monitor, you can configure Virtual JaguarX to display graphics in 720p or 1080i resolution. In this version of the emulator, only the gameplay will be shown at those high resolutions, but the rom list menu will still be shown at 480, no matter what you configured.

To configure a high resolution, select a game in the rom list menu. After that, the emulator will show the "RECOMMENDED OPTIONS" screen. Go to the last option ("Video Mode") and select your desired resolution (480, 720p or 1080i) and after that press START to begin playing. The game will be displayed in your selected resolution.

Furthermore: you only need to do this one time. The next time that you select another rom, the emulator will "remember" your selected resolution, and it will configure it automatically as the "recommended option" (although you can change it again if you want).

Please, note that I don't own an HD TV, so I have not tested the high resolution modes myself, but beta testers have confirmed that it is working well (thank you very much to darknior for testing this!).

Please, keep in mind that the emulation is still not perfect. Even games marked in green color are not perfect (especially speaking about the sound emulation). Green color does not mean "perfect gameplay". Green color means that you can play and enjoy the game without major problems, although the emulation in many cases is not 100% accurate (or even the sound does not work at all).

It is not needed that you change anything, because the emulator will try to select the best options automatically. Anyways, here is a description of the options, because you CAN change them manually if you want:

Frameskip: The emulator will skip the emulation of some frames. This can help to make the emulation faster.

Sound emulation: The DSP is the module that makes the sound in the Jaguar. This option lets you overclock this unit, to make the emulation faster (although the quality of the sound will be worse).

GPU Speed: The GPU (Graphic Process Unit) is the module that makes the complex graphics in the Jaguar. This option lets you overclock this unit, to make the emulation faster (although you may face graphical glitches).

Force FPS: You can select an amount of FPS (frames-per-second) and the emulator will try to "overclock everything dinamically" in a smart way, in order to achieve that frame rate. In fact, you will see that in many games, the recommended configuration is "Force 50 FPS", which was the default speed for many Jaguar NTSC games.

This is not usefull for every game, because sometimes the synchronization of the modules is made by one of these modules, and if you overclock it, the game can be even slower. As allways, the recommended settings are usually the best.

There are even some games where you will see that the recommended configuration is forcing a lower number of FPS (not 50). This is normal, don't get worry by that

Use BIOS: The "BIOS" is that animation that played when selecting a game (with the red "Jaguar" word). You can select to play this BIOS or not. Many games work both with or without BIOS, so in these games, the emulator will recommend you to skip the animation. Other games do require to use BIOS (like Rayman) and the emulator will recommend you to USE BIOS automatically. And there are even games that require to NOT use the BIOS (for example Wolfenstein 3D) and the emulator will recommend this to you too. Shortly: you will not have the need to touch this option, as the emulator selects it properly for you.

Video Mode: You can choose between 480, 720p or 1080i. The option that you chose, will be remembered by the emulator, and it will be recommended in the future for every game (so, it is not needed that you configure it all the time). Note that 720p and 1080i resolutions will only be used during the gameplay, but the rom list is still at 480 resolution.

NOTE: The emulator will suggest the optimal configuration options for a NORMAL XBOX. If you have a Trusty Xbox, these options will be valid in cases where no overclocking has been selected, and even in cases where the "Force FPS" is used, because this is a smart option that will overclock the systems considering the speed of your machine. But some games have a recommended configuration with fixed overclocking values (for example, Overclock Sound x3, or GPU x4...). In these cases, it's possible that the game runs a bit faster than normal if you have a Trusty Xbox. If this is the case, you will have to change a bit the configuration options manually.

To install the emulator, simply copy it to your hard disk, and put the roms inside the "roms" folder.

If you had the previous version of Virtual JaguarX, simply overwrite the old folder with the new one. You will even keep you saved games if you keep the content of the "eeproms" folder.

The image of the screen is the logo.jpg one. You can replace it if you want. The background music is the BGM.ogg file, and you can also replace it if you want.

You must keep in mind these 3 things:

* This version of the emulator only works from hard disk. Running from DVD is not possible, sorry.

* Roms must be placed, as allways, in the "roms" folder.

* When you choose a game, it will spend a bit more time to start than in previous versions, although after that, everything will run faster and better.

As far as the key mapping is related, you know that the Jaguar has 3 standard buttons (A, B and C) and a numeric keypad. The standard buttons are the most used, and they are mapped in the Xbox buttons A, B and X. After that, we must decide which is the better way to map the numeric pad. At the moment I have mapped the buttons in this way: START = 0, Y = 1, Black = 2, White = 3, Left Trigger = 4, Right Trigger = 5, dPad UP = 6, dPad Right = 7, dPad Down = 8, dPad Left = 9. Anyways, feedback will be very well received, to discuss the best way to map all these buttons.

You can exit of the game pressing START+BACK simmultaneously. You can launch a very limited in-game menu pressing BACK to change the frameskip. In fact, there is only one options that can beconfigured by the user:

* Frameskip: The default value is ZERO, because many games run at full speed (or at least at playable speed) without using frameskip. But if you play a game that runs slow, maybe increasing the frameskip can help a bit to make the game playable. Please, be warned that increasing the frameskip in the middle of the game is possible, but decreasing frameskip in the middle of the game can make it crash (you probably will have to re-launch the rom).

There are some games that work at full speed, the sound effects are good, but the music is crap (because sometimes the quality of the sound can be very bad when overclocking the sound processor). If this is your case, and the music is so bad that you prefer to mute it, keep in mind that several Atari Jaguar games can mute the music pressing the START button (which is mapped to the '0' button of the Jaguar) and you can turn on the music again pressing START again.

So, for example if you are playing Double Dragon 5 or Evolution - Dino Dudes and the music is annoying, press START. The game will be still at full-speed, you will hear the samples perfectly (which is way better than playing without sound) and the music will be muted.

In several other games, the music with overclocking is tolerable or even good, so there is no need to mute it.

It has been reported that the game "Tempest 2000" sometimes starts with graphical glitches if you use the recommended configuration. If this is the case (if the first "pipe" is not drawn properly) exit the game and select it again in the rom list. If the game starts properly, it will run properly all the time.

v0.98
-----

* Full-screen playing

* HD support 720p and 1080i in the gameplay (the GUI is still shown at low resolution)

* Noticeable speed improvement

* Improved compatibility (Worms, Soccer Kid...)

* Better savegames management

* SDL Video code replaced with Xbox native code

* Emulator splitted into two executables (GUI and core)

* Background music in the GUI

* Screenshots support in the GUI

* Bugs fixed in rom list, now a lot of roms can be used.

* Better joystick management


v0.95b
------

* The emulator suggests the recommended configuration for every game.

* Added the possibility of overclocking the GPU

* Added an option to "Force FPS", overclocking dynamically both the GPU and the DSP to achieve the desired frame ratio.

* Added an option to show or not show the BIOS animation at the begining of every game. This is very important to play some games that don't like the BIOS, like Wolfenstein 3D (that game was not playable in the past version).

* Replaced all the SDL code related to the joypad, with DirectInput code.

* Fixed a bug that prevented to play games with strange video resolution changes, like Doom, Evolution - Dino Dudes, or Trevor McFur. In the past version of the emulator, these games only show a black screen. In this version they are playable, although the aspect ratio is not correct yet.

* Fixed some bugs here and there

* Lots of small optimizations here and there, to improve the global speed of the emulator.

* Increased the size of the rom list in the user interface



v0.90
-----

* Initial version

As allways, I want to say thanks to all the people that helped me in this port: Neobomb, Hyper_Eye, Madmab, Freakdave, weinerschnitzel, XtecuterX73, darknoir, the Surreal64 CE team, the creators of the original Virtual Jaguar emulator (nwagenaar, Caz, Adam Green, Aaron Giles, David Raingeard, Bernd Schmidt, Sam Lantinga, Ryan C.

--------------Zx Spectrum Xtras-----------------
----------------Control Scheme------------------

Most games start simply by pressing Start Button (in 2nd controller for a two player game if possible), some other need extra key, usually is Fire (A Button), a number (Right ThumbStick), Enter or Space (X,Y) or a Dichotomous choice (White/Black).

------Keymappings for MOST games:

START Button Start Game

Left Thumbstick Move
DPAD Move

A Button Action/Fire
B Button Secondary OR Up (to Jump)
X Button Space Bar
Y Button Enter

BACK Button Delete

Right Thumbstick Numbers 0-3 (Up 0 | Left 1 | Down 2 | Right 3)
BACK+RT Numbers 4-7 (Up 4 | Left 5 | Down 6 | Right 7)

WHITE Button Dichotomous choice (usually Y - Yes)
BLACK Button Dichotomous choice (usually N - No)

BACK+WHITE Fast Forward

------Keymappings for Simulation/Racing games:

Left Trigger Accelerate
Right Trigger Deccelerate
A Button Accelerate
B Button Deccelerate

------Keymappings for Rotary games:

Left Trigger Rotate Left
Right Trigger Rotate Right

------Keymappings for 3D games:

Right Thumbstick Look/Aim

------Special Keymappings

Notice that certain games requires a special number of keys to control (strategic, simulation, etc). All of those games has is own control scheme. For those games we prepared buttonlist file. Mark YES in “Show button list instead of keyboard” in emulator menu, and in game screen press LTHUMB, you will see a list with possible actions for the running game. If you go to the in-game menu (RTHUMB) and press "Start", you will see action attached to a concrete button on pad. These can also be seen in the control configuration (emudefs or mappings) menu's. You can also take a look on game manual.
