Overview

Jazz Jackrabbit 2 is a 2D platformer that the native Jazz2 engine replays on modern machines. REG-Linux groups it under ports and relies on the original DOS data so the experience matches the classic release.

Quick reference

  • ROM folder: /userdata/roms/jazz2
  • Accepted format: .game
  • Emulator: jazz2 (native)
  • System group: ports

BIOS

Jazz2 does not require a BIOS dump.

ROMs

Copy your Jazz Jackrabbit 2 installation (Steam, GOG, or disc) to /userdata/roms/jazz2/. The folder should include the full game files—J2Config.exe, J2Snippet.dat, etc. Once the data is in place, create an empty marker file such as:

touch "/userdata/roms/jazz2/Jazz Jackrabbit 2.game"

This tells EmulationStation to list Jazz Jackrabbit 2 in the ports section. Keep the file names and capitalization as they appear on Windows to avoid mismatches.

Emulators

Jazz2 Native

The jazz2 binary (BR2_PACKAGE_JAZZ2_NATIVE) runs the port. It respects standard video/input options, so use the Quick Menu to adjust scaling, shader overrides, or controller bindings.

Controls

Jazz Jackrabbit 2 was designed for keyboard (arrow keys + Z/X) but also supports controllers. Assign jump/shoot to face buttons via REG-Linux’s controller settings and keep the D-pad/analog stick for movement.

Troubleshooting

  • If the title does not appear, make sure the .game file exists and that the ROM folder contains the complete installation (including data directories).
  • Delete /userdata/system/configs/jazz2/ to clear user-specific tweaks when switching between releases or mods.
