| Readme: | Jazz2 port for MorphOS
**********************
Open source reimplementation of Jazz Jackrabbit 2
https://de4th.dev/jazz2/
https://github.com/deathkiller/jazz2-native
Requirements:
-------------
- MorphOS 3.20
- SDL3 package (sdl3.library 3.4.17 or later)
- 3D graphics card with at least 64 MB of VRAM
- Original game data files: copy them into the "Source" drawer, they are
converted into the "Cache" drawer on the first launch
- A gamepad is highly recommended (rumble is supported, I recommend the
GameSir G7 SE)
Known bugs / limitations:
-------------------------
- Some effects are not perfect yet (the shield for example)
- Online multiplayer is disabled
My tests:
---------
Mirari with an X1950: fullscreen 1920x1080x16, about 100-120 FPS
History:
--------
17.10.2026
- Update to the 3.9.0 release
- Now built with libXMP and the SDL audio backend (no more OpenAL and
openmpt)
- Built with SDL 3.4.17, now using sdl3.library
- Uses the system vorbisfile.library for Ogg Vorbis files
- Larger audio buffer (2048 samples)
- Ambient sounds (torch fire of the castle levels) kept at the 3.8.0
volume, 3.9.0 doubled it and it sounded like a crackle
- GL1 backend updated for the new rendering of 3.9.0
- The fullscreen resolution chosen in Options / Graphics is now restored
at startup and with F11 / Alt+Enter
- Settings of the previous version are kept
23.08.2026
- Update to the 3.8.0 release
- GL1 backend updated, AltiVec is no longer needed
- Local multiplayer enabled
20.08.2026
- Built with SDL 3.4.14 and OpenAL 1.24.3 using the SDL3 driver
- Added a GL1 backend with FBO support, multitexturing...
- Logs redirected to a file (jazz2.log)
- Options / Graphics: added VSync, resolution selection and true
fullscreen support
- Added AltiVec support for software rendering (effects, lighting,
water...)
- Optimized cache file generation and added a message for the first
launch
