My OldBoy! - GBC Emulator

Fast GBC emulation with save states and ROM patching

My OldBoy! brings the Game Boy Color library to life with high FPS and a focus on efficiency. An ASM-optimized core drives its speed, so menus feel snappy and games respond promptly, giving classics a fresh lease of life without getting in the way of play.

Feature-wise, it delivers the essentials that matter. Save states let you freeze progress at any moment, which is perfect for tricky boss runs or quick pick-up sessions. ROM patching is supported as well, so compatible patches can be applied directly, removing the need for external tools. The interface is solid and customizable, offering a clean layout with enough toggles to tailor the experience to your liking without overwhelming you.

There are meaningful trade-offs to consider. File management can get messy if you move or duplicate games and saves across folders, and the emulator will not step in to clean that up. There is no skin support, so you cannot swap in different visual overlays to change the look. Infrared features are limited, which means certain hardware-specific functions from the original handheld may not translate here. Most importantly, the app does not perform periodic auto saves. If your battery gives out before you manually save or create a save state, progress will be lost.

Available as a free version, My OldBoy! is most compelling for players who value speed, straightforward controls and practical tools like save states and patching. Just be proactive about storage organization and make saving a habit. If you can live without skins and do not rely on IR features, this is a focused, high-performance GBC emulator that keeps the spotlight on the games themselves.
