GearColeco Core for RetroArch: Supported Features and Scope

GearColeco is an open source, cross-platform emulator for the ColecoVision and Coleco ADAM, written in C++. The official libretro documentation lists it as the RetroArch core for those two systems. Its emulation foundation is described as an accurate Z80 core, including undocumented opcodes and behavior.

What the core emulates

• According to the official documentation, the core targets two systems:
• - ColecoVision — the home console.
• - Coleco ADAM — the computer system, which the feature table separately ties to disk control support.

Frontend features reported as supported

The documentation's feature table marks the following as supported by the core: restart, screenshots, saves, save states, rewind, run-ahead, netplay, core options, memory monitoring for achievements, RetroArch cheats, controls, remapping, subsystem, softpatching, and crop overscan. Disk control is marked supported with an ADAM annotation, indicating it applies to the ADAM side of the emulator.

Capabilities the documentation marks as unsupported

The same table marks native cheats, multi-mouse, rumble, sensors, camera, location, username, language, and LEDs as not supported. Note the distinction between native cheats (unsupported) and RetroArch cheats (supported): cheat handling runs through the frontend rather than the core itself.

Practical implications for setup

Because saves, save states, rewind, run-ahead and netplay are all listed as supported, the usual RetroArch-level workflows for these features are documented as available with this core. Softpatching support means patch-based content modification is handled at the frontend level. Controls and remapping being supported means input configuration is expected to work through RetroArch's standard input menus.

Multi-mouse, rumble, sensors, camera and location are all absent, so setup should not assume support for multiple mice, haptic feedback, motion sensing, camera input, or location services. ADAM users should note that disk control is scoped to ADAM in the documentation rather than marked as universally available.

Limits of this summary

The source documentation cited here does not enumerate step-by-step installation instructions, specific BIOS file names, or per-option core option values in the material summarized. Those details should be taken from the current official libretro core page rather than assumed from this overview.
