Use chroot64 terminal
- type
mkdir testbuild
cd testbuild
Download and extract source code to /mnt/data/arm64/testbuild/
Should look like:
/mnt/data/arm64/testbuild/openjazz-oga/
Make necessary changes to the controls.cpp and video.h files if needed. Look bellow for changes.
Now go back to chroot64
- type
cd openjazz-oga - type
make -f Makefile.sdl2
Let it build. Your binary should be located in the root openjazz-oga folder.
Now create your OpenJazz.sh file
#!/bin/bash
cd /roms/ports/openjazz/
./OpenJazz -f "$(pwd)/gamedata" > logfile
Create a folder in ports called openjazz.
Place the compiled binary in OpenJazz binary and openjazz.000 from the root folder to the newly created openjazz folder.
Create a folder called gamedata, place your game data in this folder.
You should now have these items
openjazz/gamedata/
openjazz/OpenJazz
openjazz/openjazz.000

OpenJazz - http://www.alister.eu/jazz/oj/
is a free, open-source version of the classic Jazz Jackrabbit™ games.
OpenJazz can be compiled on a wide range of operating systems, including Windows, macOS, GNU/Linux and *BSD. Also ports are available for some homebrew platforms, for example Wii and PSP, Nintendo Switch, PlayStation Classic.
To play, you will need the files from one of the original games.
With the demise of DOS-based operating systems, it has become necessary to use emulators to play old DOS games. Jazz Jackrabbit™ deserves more - and would benefit greatly from new features.
is a PC platform game. Produced by Epic Games (then Epic MegaGames), it was first released in 1994. The fast-paced, colourful gameplay proved popular, and the game won PC Format's Arcade Game of the Year award. Many people still fondly recall the shareware versions.
OpenJazz was started on the 23rd of August, 2005, by Alister Thomson. Academic pressures put the project on hold until late December 2005. The source code was released on the 25th, and the first version with a degree of playability was released on the 15th of January. Since then, a variety of ports have been released by other people.
More academic pressures meant there were few updates over the following few years, but in 2009 a multiplayer version was released.
SDL2 support was added by KranKRival for the Nintendo Switch and partially ported back over by Swingflip for ports for classic consoles.
OpenJazz is available under the GNU General Public License version 2 or later,
see licenses.txt for additional information.
Enter to choose a menu option, Escape to go back to the previous menu.
F9 to view in-game statistics, P to pause.
Alt + Enter switches between full-screen and windowed mode.
The other controls are configurable via the "setup options" menu. By default, the controls are as follows:
- Left and right arrow keys to move left and right.
- Under Windows,
Alt Gr (right Alt)to jump and theSpace barto shoot. - Under Linux, the
Space barto jump andleft Altto shoot. Right Ctrlto change weapon.
Additionally, most game controllers and joysticks that SDL recognizes can be used. However, not all axes or buttons may be available.
Needed:
- SDL 1.2.x library (https://libsdl.org/).
OR
- SDL 2.0.x library (https://libsdl.org/).
Optional:
- SDL_net 1.2.x library (https://www.libsdl.org/projects/SDL_net/)
OpenJazz ships a basic Makefile that may be used and adapted to the specific
needs of the user or platform where it shall run. For network play, you need a
platform which natively provides sockets or use SDL_net, then either define
USE_SOCKETS or USE_SDL_NET in the Makefile. On the Windows platform, the
socket library (-lws2_32) is needed while linking.
For UNIX systems also an autoconf script is provided, used like this:
./configure # `--help` lists options
make [install]
Further (partly outdated) instructions are available at: http://www.alister.eu/jazz/oj/build.php
DATAPATH- use a fixed path for data filesHOMEDIR- use the user's home directory for data filesSCALE- enable scaling of the video output (i.e. Scale2X...)FULLSCREEN_ONLY- disable window mode, useful for console ports
Execute OpenJazz, depending on the platform and compile time options, the
data files are expected to be under different paths (see above). You can
also specifiy a game folder as command line argument.
