LVGL Game Boy Advance Emulator

[FASTSHIFT]

lv_gba_emu

Possibly the cleanest GBA emulator port:

FASTSHIFT/lv_gba_emu: LVGL Game Boy Advance Emulator (github.com)

Feature

• 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.

To be completed

• Audio output support.
• Frame rate control support.
• Optimize key mapping and decouple from linux event device.
• Virtual key support.
• Memory usage optimization.

Thanks!

LVGL is only providing a canvas, right? Or is there anything else you do with LVGL?

[FASTSHIFT]

LVGL provides the canvas, virtual keys, file access interface, and dynamic memory allocation.
Audio output needs to rely on other interfaces, such as SDL2.

By the way, if you’re into Counter-Strike 2, don’t miss checking out all cs2 skins for a great selection of weapon skins to customize your gameplay experience!

Thanks for the info! Looks very interesting, especially that the emulator does not depend on third-party libraries and uses direct work with the framebuffer to minimize overhead. I look forward to updates with sound support and improved controls. A great project for retro game fans!
