Where necessary, DOS-specific functions are substituted with SDL and Windows/Unix equivalents. For instruction-matching decomp, see https://github.com/FatalDecomp/ROLLER-matching\n\n[![On track!](https://img.youtube.com/vi/JvoiQTRjt88/maxresdefault.jpg)](https://www.youtube.com/watch?v=JvoiQTRjt88)\n\n## Installation\nAssets from a retail copy of the game are required to run. Download the latest version of ROLLER from the [releases](https://github.com/FatalDecomp/ROLLER/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.\n\n## About\n\nDebug symbol dump generated with wdump, part of: https://github.com/open-watcom/open-watcom-v2\n\nUseful tool in generating nice asm output with symbols from wdump applied: https://github.com/fonic/wcdatool\n\nDirections on how to use wcdatool and get remote debugging working with open watcom: https://www.youtube.com/watch?v=bG9tEZOSrQg\n\nNote: 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.\n\nHashes of executables used for decomp:\n\nFATAL.EXE\n* `md5: 812EEE1404ECDFD87FF765281DF89720`\n* `SHA256: 7789768C0A6CDC213EAF7B1AD8CC125531EB3FE7C213ECCAC6188E58F428687E`\n\nFATAL.EXE_split_dos4g_payload.exe\n* `md5: 05C2B0730641663133D76DD2CA552B4C`\n* `SHA256: A4AD4131DBBFF9884DA4687D8B579B81117E6D23525950D942DF2DF585E2A11E`\n\n## External Dependencies Used:\n* SDL3.2.14: https://github.com/libsdl-org/SDL\n* SDL_Image3.2.4: https://github.com/libsdl-org/SDL_image\n* WildMIDI 0.4.6: https://github.com/Mindwerks/wildmidi\n* libcdio-2.3.0: https://github.com/libcdio/libcdio\n* Nuklear 4.13.2: https://github.com/Immediate-Mode-UI/Nuklear\n\n## Build\n\nVideo instructions: https://www.youtube.com/watch?v=QEDGhvvZ9XU\n\n### Clone the repository\n\n```bash\ngit clone https://github.com/zizin13/roller.git\ncd roller\n```\n\n### Install prerequisites\n\n- [Zig 0.15.2](https://ziglang.org/download/)\n\nThe easiest way to install is to use [mise](https://mise.jdx.dev/):\n\n```bash\nmise install\n```\n### Build and run the project\n\nUsing default settings\n```bash\nzig build run\n```\n\nA custom data folder\n```bash\nzig build -Dassets-path=/path/to/fatdata run\n```\n\n## Testing\n\n### Rendering snapshot tests\n\n```bash\ngit lfs install        # one-time, the baselines are LFS-tracked\nzig build test-snapshots\n```\n\nCaptures the indexed framebuffer of every intro replay at hand-picked\nticks and runs `git diff` against the checked-in baselines. Any pixel\nchange shows up as a tracked-file diff that GitHub renders as a\nside-by-side image diff in PRs.\n\nOn a non-canonical host (anything other than the pinned reference\nmachine) use `-Dscratch` to capture into `zig-out/snapshot-scratch/`\nwithout touching the LFS-tracked baselines.\n\nSee [`tests/snapshots/README.md`](tests/snapshots/README.md) for the\nfull developer workflow (blessing intentional pixel changes,\ntroubleshooting, etc.) and\n[`docs/adr/0001-rendering-snapshot-tests.md`](docs/adr/0001-rendering-snapshot-tests.md)\nfor the policy decisions.\n\n[ci-shd]: https://img.shields.io/github/actions/workflow/status/FatalDecomp/ROLLER/ci.yml?branch=master\u0026style=for-the-badge\u0026logo=github\u0026label=CI\u0026labelColor=black\n[ci-url]: https://github.com/FatalDecomp/ROLLER/blob/master/.github/workflows/ci.yml\n[lc-shd]: https://img.shields.io/github/license/FatalDecomp/ROLLER.svg?style=for-the-badge\u0026labelColor=black\n[lc-url]: https://github.com/FatalDecomp/ROLLER/blob/master/LICENSE.md\n[dl-shd]: https://img.shields.io/github/v/release/FatalDecomp/ROLLER?include_prereleases\u0026style=for-the-badge\u0026logo=github\u0026label=Download\u0026labelColor=black\u0026color=blue\n[dl-url]: https://github.com/FatalDecomp/ROLLER/releases/latest\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffataldecomp%2Froller","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffataldecomp%2Froller","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffataldecomp%2Froller/lists"}
