About NeoBox

A native macOS Neo Geo emulator with built-in Geolith, CRT shaders, save states, gamepad hot-swap, and per-game memory cards. No setup. Just play. Xbox, PS, Switch Pro, and MFi controllers work over USB or Bluetooth with zero configuration. Each shot is the 304×224 native frame, with the CRT shader baked in if you've got it on. The sidebar is always one click away from the next game. Every choice has a sensible default, the preferences pane is for when you want the arcade feel of a CRT, or when a particular cart needs MVS mode.

About Overplane

Overplane is an AI code generation and build system that verifies and safely compiles plain-language specs into working, verified code. Container-sandboxed agents, replayable builds, and multi-agent support. Overplane combines popular AI coding agents with containers, spec-driven development, and formal verification to create a safer and more reliable AI coding workflow. Overplane keeps the speed and fixes the rest in three moves: contain the agent, wrap it in a real build system, and verify the plan before the code exists.
