Blues Brothers, Jukebox Adventure & Prehistorik 2 engine reimplementation (SDL1)

Blues Brothers

This is a rewrite of the Blues Brothers and Blues Brothers: Jukebox Adventure game engines developed by Titus Interactive.

There is also support for Prehistorik 2.

Requirements

Blues Brothers

The data files of the Amiga or DOS version, full game or demo, are required.

*.BIN, *.CK1, *.CK2, *.SQL, *.SQV, *.SQZ

For sounds and music, the Amiga version files or the ExoticA set need to be copied.

Jukebox Adventure

The data files of the DOS version are required.

*.EAT, *.MOD

Prehistorik 2

The data files of the DOS version, full game or demo, are required.

Changes

Compared to the original DOS executables, the rewritten engines feature:

• horizontal scrolling
• configurable screen size
• dynamically resizable window to control game screen size
• in-game screen controls for screen size, scale & palette
• on-screen messaging
• game cheats: unlimited lifes and energy, no hit
• game pad support with a user-defined jump button

Screen controls

In addition to the default controls, the engine provides several convenience in-game keys for display control.

The screen size lock allows to hold a given game screen size whilst manipulating the window or scale.

In-game palette cycling is only available in Prehistorik 2.

J	Configure jump button
O	Restore original scale & screen size
P	Pause game
S	Toggle screen size lock
