MasterGear vs Mira

MasterGear emulates 8-bit SEGA consoles and computers, including MasterSystem, GameGear, SG1000, SC3000, SF7000, Mark2, and Mark3. It runs on Windows, Linux, and Android. The maker says hobbyists can use it to debug software without rare development hardware. Documentation reports support for about 98% of the maker’s SMS, GG, SF7000, SC3000, and SG1000 cartridge and disk images, while noting compatibility is not complete. Emulated hardware includes the Z80 CPU, console video processors, SN76489 sound, and Mark3 YM2413 FM sound. It can save and load emulation states, but state files are not guaranteed to work across versions on different hardware. Other listed features include automatic GZIP ROM handling, MIDI soundtrack logging, a built-in debugger, cheat support, and NetPlay. Windows and Linux are free; the Android plan costs 430.00 USD once. Game ROM images are not included, and source code is not publicly available.

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.
