# Blues Brothers
This is a rewrite of the [Blues Brothers](https://www.mobygames.com/game/blues-brothers) and [Blues Brothers: Jukebox Adventure](https://www.mobygames.com/game/blues-brothers-jukebox-adventure) game engines developed by [Titus Interactive](https://www.mobygames.com/company/titus-interactive-sa).

There is also early support for [Prehistorik 2](https://www.mobygames.com/game/prehistorik-2).
## Requirements
### Blues Brothers
The data files of the Amiga or DOS version, full game or [demo](https://archive.org/details/TheBluesBrothers_1020), are required.
```
*.BIN, *.CK1, *.CK2, *.SQL, *.SQV, *.SQZ
```
For sounds and music, the Amiga version files or the [ExoticA](https://www.exotica.org.uk/wiki/The_Blues_Brothers) 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](http://cd.textfiles.com/ccbcurrsh1/demos/pre2.zip), are required.
```
*.SQZ, *.TRK
```
## Changes
Compared to the original DOS executables, the rewritten engines feature :
- horizontal scrolling
- configurable screen size
- game cheats : unlimited lifes and energy, no hit
## Running
By default, the executable loads the data files from the current directory.
This can be changed using command line switches.
