What is WinFellow?

WinFellow is an emulator that reproduces Atari ST/STE/TT hardware on Windows. It emulates the CPU, custom chips, video output, sound, floppy and hard disk controllers, and other peripherals, allowing you to run original game images, demos, and productivity software. WinFellow aims for compatibility and fidelity while providing an easy-to-use GUI for configuration.


Why use WinFellow for retro Atari ST gaming?

  • Accurate emulation of core Atari ST hardware.
  • Windows-native interface—no need for complex command-line setups.
  • Good compatibility with many ST game images and demos.
  • Active configuration options for display, sound, input, and disk images.

Preparing Files: ROMs, Disk Images, and TOS

  • TOS ROM: WinFellow requires a TOS image (the Atari ST BIOS). Acquire a TOS ROM legally (from your own hardware or authorized sources). Place the ROM in WinFellow’s configured ROM directory.
  • Disk Images: Games usually come as .ST, .MSA, .IPF, or .STX files. Store them in a tidy folder structure (e.g., /Games/AtariST/) for easy access.
  • Hard drive images: For multi-game setups, create a virtual hard disk image and install multiple games/folders inside it.

Installation and Basic Setup

  1. Download WinFellow (ensure you’re using a trusted source).
  2. Extract the program to a folder (no complex installer required).
  3. Place TOS ROM(s) into the ROM folder and point WinFellow to that folder via Options > ROMs.
  4. Configure input: map your keyboard, joystick, or gamepad under Options > Controllers. Many modern gamepads map well using XInput.
  5. Point floppy drive A: and B: to disk images when loading games, or attach a hard disk image for more convenience.

Display and Video Tricks

  • Screen Size and Stretching: WinFellow allows scaling and aspect ratio options. Use integer scaling if available to reduce pixel distortion, or enable aspect correction to mimic the original 4:3 ratio.
  • Vertical Sync and Frame Throttling: Enable vsync or frame limiting to avoid running games too fast on modern CPUs.
  • Color Palette: Some games expect the ST’s 16-color palette. Use palette correction if colors look off.
  • Multiple Monitors: Pin the emulator to a single monitor and set full-screen resolution to match your monitor to avoid blurriness.

Sound and Latency

  • Audio Driver Selection: Choose SDL/DirectSound/ASIO options available in WinFellow for lowest latency.
  • Sample Rate: Set the sample rate to 44100 Hz for best compatibility with original music/sfx.
  • Buffer Size: Reduce buffer size to lower latency, but avoid underruns; increase if you hear crackles.

Input: Joysticks, Gamepads, and Keyboard

  • Use modern USB gamepads with XInput mapping for the best experience.
  • Configure digital vs. analog behavior depending on the game (many ST games expect digital 8-way input).
  • Map hotkeys (save state, reset, disk swap) to convenient keys or buttons.

Disk Swapping and File Transfer

  • Hot-Swapping: WinFellow supports swapping disk images while running; assign a hotkey for quick changes in multi-disk games.
  • Mass-Installing: Use a hard disk image to install many games and reduce disk swapping.
  • File Transfer: Use ATR/ST image tools on the host to add files into a hard disk image, or set up a shared directory if WinFellow supports host-guest file access.

Saving and State Management

  • Save States: Use save states to capture exact game moments; remember save states can be emulator-version specific.
  • In-Game Saves: Prefer in-game saves where possible for compatibility with copy protection or game logic that checks for authentic saves.

Performance Troubleshooting

  • Game Runs Too Fast: Enable frame limiting or switch CPU to a lower clock mode.
  • Sound Glitches: Increase audio buffer or try a different audio backend.
  • Graphics Corruption: Verify correct TOS ROM and try different video/compatibility settings.
  • Input Lag: Lower audio buffer, use poll rate settings for USB devices, or try a different controller backend.

  • Disk image utilities: Tools to convert and mount .ST/.MSA/.IPF files.
  • TOS switcher: Utilities that let you test multiple TOS versions quickly for compatibility.
  • Save-state managers and backup tools to prevent corruption.

  • Only use TOS ROMs and game images you legally own or are distributed freely by the copyright holder.
  • Many abandonware sites exist for vintage games, but legality varies—prefer authorized or public-domain releases.

Example Setup: Smooth Retro Experience (step-by-step)

  1. Place TOS 1.02 ROM in WinFellow ROM folder.
  2. Create a 512 MB hard disk image and mount it as ADFS.
  3. Copy several .ST game images into a /Games folder on the hard disk image.
  4. Map an Xbox-style controller with D-pad to digital joystick, A/B to fire/button.
  5. Set audio to 44100 Hz, buffer 256 ms, enable vsync, and use integer display scaling.
  6. Launch a game, use hotkey to switch disks when needed, and use save states for difficult sections.

Final Tips and Community Resources

  • Join Atari ST retro communities and forums to get game images, TOS variations, and setup tips (observe copyright rules).
  • Try demo scene releases to stress-test synchronization and sound.
  • Keep multiple TOS versions handy—some games require specific revisions.

If you want, I can:

  • Provide step-by-step screenshots (describe your OS and WinFellow version).
  • Create a recommended settings profile for your hardware (CPU/GPU/monitor).
