ROLLER

This project aims to implement all the functionality of the 1995 game Whiplash/Fatal Racing in a way that builds and runs on modern PCs. Where necessary, DOS-specific functions are substituted with SDL and Windows/Unix equivalents. For instruction-matching decomp, see https://github.com/FatalDecomp/ROLLER-matching

Installation

Assets from a retail copy of the game are required to run. Download the latest version of ROLLER from the releases page and extract wherever you want. On the initial launch you will be prompted to select a CD image (CUE/BIN or ISO) to extract the assets from. Press the ` key to access additional settings and the debug log.

About

Debug symbol dump generated with wdump, part of: https://github.com/open-watcom/open-watcom-v2

Useful tool in generating nice asm output with symbols from wdump applied: https://github.com/fonic/wcdatool

Directions on how to use wcdatool and get remote debugging working with open watcom: https://www.youtube.com/watch?v=bG9tEZOSrQg

Note: wdump symbol offsets do not account for DOS4GW.EXE. Load FATAL.EXE_split_dos4g_payload.exe (FATAL.EXE with DOS4GW.EXE split off, generated by wcdatool) into Ida/Ghidra to have matching symbol offsets.
