Changes

The 3DS does include native firmware for a GBA mode which was mainly used to run ambassador releases instead of having to develop an emulator for them. Because it's technically running a "virtual" GBA, it can't provide features that are normally available on other emulators, such as savestates, screen filtering, or sleep mode, however it does have high compatibility with the exception of cartridges with special hardware, for example, WarioWare Twisted, which has a gyroscope built in. If you're using an old 3DS/2DS, this is the best option to play GBA games.

* open_agb_firm <i>(Name not finalized)</i> - A custom FIRM payload that takes advantage of the built-in GBA firmware, it's still in early development but has an alpha build available. The major advantages of this oaf compared to VC injection is that it performs faster and there aren't any issues with the sound, it utilizes the native hardware (even with VC injection there are issues with the sound, ex.: "Fire Emblem"). It can load the ROM through the SD card instead of having to convert and install them, but needs to be launched on boot instead of being able to use the 3DS HOME Menu (there's ways to make a forwarder for in on the HOME menu, but requires additional setup to get it to work). One major issue is there's a chance that it may not detect the correct save format or will corrupt the existing save file so make sure to backup your saves beforehand (they are currently trying fix it by having a better database for save detection, if you're interested [https://github.com/profi200/open_agb_firm/issues/9 you can help]).** To install, simply put the .firm file in the <code>/luma/payloads/</code> folder and , hold START and power on to load up the chainloader to launch it. There's no way of exiting out once the program starts, so you will need to turn it off and redo the step to load it if you wanted to change games.
