Notes:
brew trust --tap drhelius/geardomelibsdl33aa93ef3; filenames colecovision.rom, coleco.rom or os7.u2). ADAM additionally needs ADAM > EOS ROM (eos.rom, 8192 bytes, common CRC32 05a37a34) and ADAM > SmartWriter ROM (writer.rom, wp.rom or wp_r80.rom, 32768 bytes, common CRC32 58d86a2a)..ddp, 160/320 KiB .dsk, ZIP archives containing one valid ADAM image, and .m3u playlists containing images of the same type. Each drive has its own recent images, playlist and write protection controls. Insert/eject affects only that drive; dropped images use an available matching drive or prompt for a destination. Gearcoleco > Open ROM... starts ColecoVision cartridges.F12 toggles fullscreen. ADAM > Controller 1 / Controller 2 selects gamepad (default), keyboard or no hand controller per port. Bindings come from Input > Gamepads or Input > Keyboard Configuration; keys mapped to a hand controller do not type into ADAM. ADAM controller choices are saved separately from ColecoVision settings.Backspace by default) or a mapped gamepad shortcut to step backwards through recent gameplay.Top+Bottom and Aspect Ratio Standard (4:3 DAR) in the Video menu.--portable, or create an empty file named portable.ini in the same directory as the application binary. On macOS, place the file next to the .app bundle.Normal letters, digits, punctuation, Return, Escape, Backspace, Tab, Shift, Control, Caps Lock and arrow keys map directly. The dedicated ADAM keys use these defaults:
| Host key | ADAM key |
|---|---|
| F1-F6 | SmartKey I-VI |
| F7 / F8 | Undo / Wild Card |
| Home / Insert / Delete | ADAM Home / Insert / Delete |
| Page Up / Page Down | Move-Copy / Store-Fetch |
| End | Clear |
| Print Screen |
Saved keyboard mappings are preserved. Use ADAM > Keyboard > Restore Defaults to adopt this layout in an existing configuration.
When ADAM owns keyboard focus, overlapping emulator hotkeys are available from the menus so SmartKeys and editing keys reach the emulated keyboard. Leaving the window releases every held ADAM key.
ADAM keyboard input follows focus automatically. In normal use, type directly; in debug mode, focus Output to type into ADAM or focus a debugger tool to use its shortcuts. F12 remains the default fullscreen shortcut.

Cartridges use ColecoVision unless Cartridge Hardware is set to ADAM.Save-directory working copy to save complete modified images in the frontend save directory, leaving source files untouched.

All slots are optional and each drive supports playlists. Update older three-slot configurations to this layout; use normal content loading for a single image or playlist.
