Jazz Jackrabbit - OpenJazz source port on RetroPie/Raspbian

Spiky

will this eventually become part of RetroPie package? (like some other ports)

tpo1990

@Spiky Yes it will. Thats my plan, to integrate Jazz Jackrabbit source port into a scriptmodule that makes it available as a package in RetroPie setup.

Im already in the middle of experimenting with this, but with Hexen 2 which is my other project. Once i have gotten Hexen 2 to work as a part of RetroPie package i will do the same to Jazz Jackrabbit and other following source port that i can get working on RPI/RetroPie. :-)

Spiky

@tpo1990 cool, thanks!

tpo1990

@Spiky Your welcome. Im nearly there with Hexen 2. It just need some small adjustments and then i will be working with getting Jazz Jackrabbit to work as a scriptmodule as well.

Good news. I have managed to create a working scriptmodule for Jazz Jackrabbit and created a pull request from my fork of the RetroPie project. Now the reviewing process can begin of the PR. :-)

Edit: The pull request has to wait for now until merge of hexen2 scriptmodule is complete.

You can get the OpenJazz - Jazz Jackrabbit scriptmodule by this command:

wget https://raw.githubusercontent.com/tpo1990/JazzJackrabbit-RPI/master/openjazz.sh -P /home/pi/RetroPie-Setup/scriptmodules/ports/

This will download the scriptmodule from my fork of RetroPie and place it into the /home/pi/RetroPie-Setup/scriptmodules/ports/
Once downloaded, go into RetroPie-Setup as usual and into the Experimental section to find "openjazz" and then install.

Once the game has been installed, it will have been installed with this file hierachy:

Game data location: /home/pi/RetroPie/roms/ports/jazz
Runcommand file: /home/pi/RetroPie/roms/ports/Jazz Jackrabbit.sh
Config location: /opt/retropie/configs/ports/openjazz
Port installation location: /opt/retropie/ports/openjazz

For registered version, replace the shareware files in the Game data location: /home/pi/RetroPie/roms/ports/jazz

I have now created a pull request for OpenJazz/Jazz Jackrabbit for the RetroPie project. Now the review can begin :-)
You can still get the same scriptmodule from my separate git repo for Jazz Jackrabbit.

@tpo1990
i love Jazz jackrabbit,
thanks!
Works great !!! TX !

tpo1990

@shavecat Me too. If you want to use your controller/gamepad, then i suggest using xboxdrv and configure it for Jazz Jackrabbit.

This will make it even better. ;-)

So it's complete? There's some graphic bugs. A line of some sort can be seen on the top of the screen when playing. The menu transitions and level select have missing animations. Maybe more stuff in-game but haven't tested it extensively. Maybe my altered compile settings have something to do with it. I'm using a pi3b+ with retropie 4.4.9.

@Darksavior The port has some issues that needs to be sorted out, but the game is fully playable.

There are some small graphics issues. It might be caused by vsync or bpp settings. You could try changing the screen resolution in game to see if it fixes it. I have set mine to 320 x 240 to eliminate white bars and to fill out the screen in 4:3.

Savestates does not appear to be working as far as my testing goes.

When i first tested the source port, there was no sound/music in game. That has been fixed in the scriptmodule. As for now OpenJazz / Jazz Jackrabbit is considered experimental.

shavecat

everything thing works great for me the sound/music and all.
but u right
Darksavior
i do have
"A line of some sort can be seen on the top of the screen when playing"

snock

Fantastic ... would there be any way to configure ESC on the joystick? Modifying some file.

Could you install the 2?

Thank you for your work.

tpo1990

@snock I use Xboxdrv driver to make my PS4 generic USB gamepad work as a keyboard. For this i use a runcommand file with configuration for openjazz and other source ports. It works great.

Maybe there is some manual setting in the openjazz config file. That would probably be your best bet to look for the ESC setting.

I'm not sure about what you mean with "Could you install the 2?"

Your welcome.

@tpo1990
Any fix's for the jazz 1 ports ?
The stage's when he run full of bugs...
And a chance to get jazz 2 also on ports ?
thanks

tpo1990

@shavecat At the moment no. I have been busy with creating ECWolf source port for RetroPie(Wolfenstein 3D with mods support).

What sort of bugs do you experience?

I have earlier investigated if Jazz Jackrabbit 2 could be built into a working binary for our Raspberry Pi and i found out that it was not possible due to hardware limitations.

I haven't checked for a long time and can not tell if it is possible or not for Jazz 2. Hopefully the new Raspberry Pi 4B will make more source port available to get working.

@tpo1990
Shame jazz 2 will be more then nice !!! will love it ;)

The bonus leve's dont work right at all...(no road all the screen is BLACK u cant see anything beside JAZZ & DIAMONDS).

luckyluca

The port is working beautifully except that the ESC key is not mapped to the joypad.
Any ideas how to map it so that it makes it possible to exit the game without using a keyboard?

please note openjazz.cfg is binary so I'm unable to edit it and look into remapping.

Many thanks
