Sega Lindbergh Rideboard Emulator

This project is an emulator for the following large scale attraction arcade games:

• Let's Go Jungle Special
• The House Of The Dead 4 Special

It's possible that this would also work for The Lost World Special, however I've never seen a real machine to test it with.

Building & Running

To build and run on Ubuntu, use the following commands:

sudo apt install build-essential git
git clone https://github.com/bobbydilley/rideboard-emulator
cd rideboard-emulator
gcc rideboard.c -o rideboard
sudo ./rideboard

You can pass the path of your serial device in when running using the following:

sudo ./rideboard /dev/ttyUSB1

Running on Lindbergh

The source and executable for a version of this software that runs on the Lindbergh has also been included.

You should run the software before starting the executable for the game, by adding this line before the game is called in the disk0/hotd4-sp/elf/game file.
