Dega vs Mira

Dega is an emulator for Sega Master System, Mark III, and Game Gear games. It runs on Windows and *NIX systems; its README names Windows 95, NT, 98, 2000, ME, and XP. The software is free for non-commercial use only, and the GitHub repository has no releases. Dega supports Python scripting for input, resets, movie playback and recording, and access to a running game's RAM. Python can be used as a module in another program or embedded in the emulator. The distribution includes memory.py, a Python memory viewer and trainer. Users can record a movie and continue recording later from a saved state. Windows provides save-state slots, and Dega also supports a gzip-compressed .dgz save-state format. Other features include loading ROMs from ZIP files, AVI encoding from movie files on *NIX, and Yamaha 2413 FM audio for machines equipped with that chip. It can also combine some games' flickering-glasses effect into a red-and-blue image for red/blue glasses. Technical information estimates compatibility at 97%.

Mira is a free, open-source AI code reviewer for pull and merge requests. It indexes repositories, using project context beyond the changed diff when assessing changes. Review results include inline comments with severity and confidence, plus a pull-request walkthrough and summary. GitHub users can apply one-click suggestions. Security analysis combines model-based review with secret scanning and OSV checks for packages added or upgraded in a request. Mira can learn custom review rules from rejected comments and recurring feedback on merged requests. It supports GitHub, GitLab, Forgejo, and Codeberg; Bitbucket support is planned. Operators deploy Mira themselves as a Docker image, storing indexes in SQLite or Postgres. Requests are routed through OpenRouter, with provider choices including Anthropic, OpenAI, Google, and DeepSeek. The maker says self-hosted deployments send no data or telemetry to its infrastructure. The source is available under Apache 2.0. The free plan includes all features; users pay model-provider costs directly.
