CD Creating

11. January 2007:
Here is the Sourcecode of my BJL-Version of the CD-encryption program.

4. January 2007:
I have altered my BJL-version of the CD-encryption program in that way, that in now runs from CD!
After starting the program from CD you can open the Jaguar-CD-player and insert the CD you want to encrypt.
ZIP-archives (each about 2.3 MB) of the CD-tracks or complete CD-images in several versions can be downloaded here:

Example: Reading from CD

Here is the sourcecode of an example-program which reads 3 graphics from CD whenever the user presses FireB and then shows them on screen .

First graphic Second graphic Third graphic

Program for choosing ChrY-colour values in 256 colour mode

ChrY-program (Uses the joypad in port 1): COLORS.ZIP (Only 3 KB)! Updated on July 14, 2001!

CRY-Viewer (Mouse-Version)

Connecting a digital mouse to the Atari Jaguar

The necessary driver software and an adapted version of the ChrY-program (mouse connected to port 2): COLMOUSE.ZIP (Only 4 KB)!

20060226: Two new demo-programs for mice and RotaryControllers including sourcecode:

TwoMice-demo
With TwoMice you can test your digital mouse at Port2, the sourcecode contains a detailed description of the userinterface.
Updated 20071230: Enhanced the interrupt-handling. OneAxis-demo
OneAxis is derived from TwoMice, it is quite optimized and evaluates only the data of one axis.

"Rotary Controller"

Variation of the Mouse-adapter for use with an Atari VCS 2600 Driving Controller:

2600 Driving Controller with Jaguar-Joyport-Adapter

The wiring is much simpler:

"Rotary Controller support in Tempest 2000"

Here is a description how you can activate the Rotary Controller Support in Tempest 2000.

Lightguns

You can attach a lightgun to Joypad-Port1 of the Jaguar, but you will need at least an adapter and most likely an internal modification of the lightgun. I had to modify both lightgun-models i own to let the firebutton trigger to close from Ground to the dataline (as the Jaguar will recognize "Ground" as "button depressed").

Adapter for Sega Lightphaser

Adapter for Sinclair Magnum

Balloons is a small lightgun-testprogram (startaddress is $4000), after calibrating the lightgun (please attach it to Joypad-Port1 of the Jaguar) you can shoot on coloured balloons moving from the bottom to the top of the screen.

Lightgun-testprogram 'Balloons' screenshot

Joypad-testing program

The program-archive JPTEST2.ZIP is about 62 KB.

The DevPac-sourcecode-archive for the old version TEAMTAP.ZIP is about 16 KB (no images included).

The DevPac-sourcecode-archive for the new version tttsource20031224.zip is about 284 KB (but all pictures are included).

This program shows which buttons on which joypad is depressed. A depressed button will be marked in green on the Joypad-image and the used TeamTap-port is marked, too. If a joypad is directly connected to the Jaguar it will be shown as connected via Port A of a TeamTap.

Updated on August 15, 2001:

Can now show simultaneously depressed keys! Also shows the ControllerType-bits C1, C2 and C3 of each port!

BJL_PAD: Joypad-Emulation via BJL-cable

As a Jaguar developer using the BJL-kit i was always frustrated by the fact that i had to remove the BJL-cable in order to test 2-player mode games. BJL_PAD (archive is about 96 kb) solves this problem, it lets you control the joypad-port from MS Windows:

BJL_PAD-Hauptfenster

Jaguar-logo patchprogram

The programarchive INTROPTF.ZIP is about 76 KB.

This program exchanges the image of the Jaguar's head on the spinning cube of the intro-sequenz.

A 64*64 16bit-Pixel CRY-file (-->8192 Bytes) is used as input.

Use of JAG-files with FLASH- or EPROM-cards

The programarchive JAG2CARD.ZIP is about 19 KB and contains the utility and its sources.

The program JAG2CARD makes it possible to load JAG-files from a FLASH- or EPROM-card.

Memory-Dump

The programarchive memdump.zip is about 4 KB and contains a program to browse through the Jaguar's memory space.
