• GBA Emulator: https://github.com/libretro/vba-next
• Test ROM: https://github.com/XProger/OpenLara

• The emulator kernel is based on vba-next and does not depend on any third-party libraries.
• Decoupled from the OS, only relying on lvgl's memory allocation and file access interface.
• Support to use GBA framebuffer directly as lv_canvas buffer, zero copy overhead.
• Audio output.
• Frame rate control.
• Multiple input device.
• Virtual key.
• Memory usage optimization(~800KB + ROM size).
• Game saves support (auto load/save).
• Game Launcher (ROM selection menu).

• Exit to Menu: Long press Select (Backspace on Keyboard) for 2 seconds.
