{{#seo: |title=Vita Homebrew Emulators (Handheld) - GameBrew |title_mode=append |image=mgbavita2.png |image_alt=mGBA }} [https://mgba.io/ mGBA] is a new generation of Game Boy Advance emulator for PS Vita. It is also available available for many platforms including Windows, Linux, macOS, [[MGBA Vita|PSVita]], [[MGBA 3DS|Nintendo 3DS]], [[MGBA Switch|Switch]] and [[MGBA Wii|Wii]]. The mGBA project started in April 2013 for the PC version with the goal of being fast enough to run on lower end hardware than other emulators support, without sacrificing accuracy or portability. Even in the initial version, games generally played without problems. mGBA has only gotten better since then, and now boasts being the most accurate GBA emulator around. Other goals include accurate enough emulation to provide a development environment for homebrew software, a good workflow for tool-assist runners, and a modern feature set for emulators that older emulators may not support. ==Features== *Highly accurate Game Boy Advance hardware support. *Game Boy/Game Boy Color hardware support. *Fast emulation. Known to run at full speed even on low end hardware, such as netbooks. *Qt and SDL ports for a heavy-weight and a light-weight frontend. *Local (same computer) link cable support. *Save type detection, even for flash memory size. *Support for cartridges with motion sensors and rumble (only usable with game controllers). *Real-time clock support, even without configuration. *Solar sensor support for Boktai games. *Game Boy Camera and Game Boy Printer support. *A built-in BIOS implementation, and ability to load external BIOS files. *Scripting support using Lua. *Turbo/fast-forward support by holding Tab. *Rewind by holding Backquote. *Frameskip, configurable up to 10. *Screenshot support. *Cheat code support. *9 savestate slots. Savestates are also viewable as screenshots. *Video, GIF, WebP, and APNG recording. *e-Reader support. *Remappable controls for both keyboards and gamepads. *Loading from ZIP and 7z files. *IPS, UPS and BPS patch support. *Game debugging via a command-line interface and GDB remote support, compatible with Ghidra and IDA Pro. *Configurable emulation rewinding. *Support for loading and exporting GameShark and Action Replay snapshots. *Cores available for RetroArch/Libretro and OpenEmu. *Community-provided translations for several languages via [https://hosted.weblate.org/engage/mgba Weblate]. *Many, many smaller things. ==User guide== If you are using your own BIOS, go to Menu > Configure, set Use BIOS if found to On and select the paths. [https://mgba.io/faq.html mGBA FAQs.] ==Controls== Triangle - Menu Cross - A Square - B Select/Start - Select/Start D-Pad - D-Pad L/R - L/R ==Screenshots==
