How to Record Gameplay from VBA (Visual Boy Advance) Emulator

VBA runs in a standard window, so you record it like any PC app.

Method 1: Screen Recording (Easiest)

• OBS Studio (Free/Open Source): Add "Window Capture" source → select VBA window. Set output to MP4/MKV. Best quality/performance.
• Xbox Game Bar (Win+G): Built into Windows 10/11. Press Win+Alt+R to start/stop.
• Bandicam / Camtasia: Paid, simpler UI.

Method 2: VBA Built-in Recording (.vbm)

• Tools > Record Movie > Start... saves a .vbm file (input log).
• Deterministic replay: Play back in VBA exactly. Tiny file size.
• Export to video: Tools > Play Movie while recording with OBS.

Method 3: Code Documentation (For Developers)

If you mean "record the game logic": comment your VBA (Visual Basic for Applications) or GBA assembly source code. Use a debugger (no$gba, mgba) to log register/RAM changes during execution.

Tips

• Set VBA video filter to "HQ2x" or "Scale2x" for cleaner upscaling.
• Disable "Throttle" (Space/TAB) while recording .vbm for fast-forward; re-enable for real-time video capture.
