It uses SDL2 for rendering.\n\nPasses [JaCzekanski/ps1-tests](https://github.com/JaCzekanski/ps1-tests).\n\nKindly reminder that Jam lang is experimental yet.\n\n```bash\nmake build\n\n# Or run:\n# LIBRARY_PATH should be where SDL2 is located, in this case is an example in MacOS\n# NOTE: MacOS requires -lobjc as well!\nLIBRARY_PATH=/opt/homebrew/lib jam -lSDL2 -C opt-level=3 -o jamstation main.jam\n```\n\nRunning it:\n\n```bash\n# Run: jamstation \u003cBIOS_PATH\u003e [GAME_PATH]\n./jamstation /path/to/SCPH1001.BIN \"/path/to/Brave Fencer Musashi (USA).cue\"\n\n# BIOS only — boots to the PlayStation shell:\n./jamstation /path/to/SCPH1001.BIN\n```\n\n- **`BIOS_PATH`** - the PSX BIOS image. The original Sony BIOS (e.g. `SCPH1001.BIN`) is copyrighted; if you don't own one, the [PCSX-Redux OpenBIOS](https://github.com/grumpycoders/pcsx-redux) is a free, open-source replacement that boots most software.\n- **`GAME_PATH`** - optional, dispatched by extension:\n  - `.cue` / `.bin` (disc image); the BIOS bootstraps it off the disc. Pass the **`.cue`**, not the game folder, its `.bin` tracks are resolved relative to the cue (multi-track and spaces in the name are fine, so quote paths with spaces).\n  - `.exe` - a PS-X executable, sideloaded after the BIOS boots.\n\n## Tested on x86 and macOS arm\n\n![Suikoden 2 running on jamstation](https://media.mas.to/media_attachments/files/116/674/503/103/746/875/original/5a53ef5936b5095e.jpeg)\n\n## Controls\n\n![PS1 DualShock Controller](https://coregamingnh.com/cdn/shop/files/PS_DUALSHOCKLG.webp?v=1737998619\u0026width=900)\n\nKeyboard maps to a digital PSX controller in slot 1:\n\n| PSX button | Key       |\n|------------|-----------|\n| D-pad ↑    | Up arrow  |\n| D-pad ↓    | Down arrow|\n| D-pad ←    | Left arrow|\n| D-pad →    | Right arrow|\n| ╳ Cross    | Z         |\n| ◯ Circle   | X         |\n| ▢ Square   | A         |\n| △ Triangle | S         |\n| L1         | Q         |\n| R1         | W         |\n| L2         | 1         |\n| R2         | 2         |\n| Start      | Return    |\n| Select     | Right Shift |\n| Quit       | Esc       |\n\n## Memory cards\n\nJamStation emulates a standard 128 KB PlayStation memory card in slot 1, so games save and load exactly as they would on real hardware.\n\nThe card is backed by a file named **`slot1.mcd`** in the current working directory:\n\n- On startup it's loaded if present (you'll see `Loaded memcard: ./slot1.mcd`).\n- On a clean exit: press **Esc** or close the window, the card is written back, so saves persist across runs.\n\nIt's a raw 128 KB image (the common headerless `.mcd` / `.mcr` format), so cards are interchangeable with emulators like PCSX-Redux and DuckStation. To start fresh, delete `slot1.mcd`; a blank card shows up as unformatted, and the BIOS Memory Card manager (or the game) will offer to format it.\n\n## References\n\n- https://github.com/allkern/psxe\n- https://github.com/stenzek/duckstation\n- https://github.com/JaCzekanski/Avocado\n- https://problemkaputt.de/psx.htm\n\n## License\n\nJamStation is released under the [MIT License](LICENSE).\n\n## Disclaimers\n\n\"PlayStation\" and \"PSX\" are registered trademarks of Sony Interactive Entertainment Europe Limited.
