Hacking AGB_FIRM?

So is 3ds backwards compatible with the gba or are the games emulated.
And if it had a gba slot would it play gba carts?

The 3ds is backwards comparable with dsi, which is backwards compatable with ds, which is backwards compatable with gba.
Each of these consoles used the hardware from the previous generation to some extent.
To run gba games the 3ds boots into a modified twl firm to boot the gba hardware buried within. Some parts are emulated (or simulated) because they weren't needed for ds backwards compatability. The 3ds stores the gamepak rom in FCram for example.

Ninty actually tried a software emulator for gba games. You can inject a gba rom into certain virtual console releases and get a buggy, and VERY slow gba emulator running. They dropped it in favor of hardware to keep their promise to the Ambassators.

Thanks. Do gba gamea run at full speed

From what I read AGB_Firm is just slot2 emulation, using some frankenstein, TWL_FIRM.

Yes most injects run at full speed.

Oh ok but why the 3ds is able to run the gba bios screen

No idea? We can also run TWL boot screen! Probably just Nintendo magic.

The TWL boot screen is as far as I know recreated from scratch, it's not the real thing.

Ok
