open_agb_firm VS 3DShell

Don't forget about emulators! Especially if you have a "new" system - you can even play some (mostly 2D) PS1 games, and some N64 games on it, and everything older. On an "old" system you are more limited though - SNES games that use a SuperFX chip (such as SM RPG, Yoshi's Island, Star Fox, and some other ones) will run slow, but Genesis and 8-bit systems will run no problems. And you can run GBA games - on "new" you can even use the system's gyroscope for games like WarioWare Twisted or Yoshi Topsy-Turvy through mGBA, and on any system you can use injects or open_agb_firm - they both run games natively using the ARM7 CPU - the same one GBA uses, carried over into the DS, and it's still included in the 3DS.

Use open_agb_firm. It's a firm, so it's activated in the same way as GodMode9, hold START while turning on the 3DS. You should be able to download it via Universal Updater. open_agb_firm uses the 3DS hardware to give you the same experience as playing on a real GBA.

That depends on how you are running the game on your 3DS. The best way is with open_agb_firm, in which case you will probably need to convert it with https://exelotl.github.io/gba-eeprom-save-fix/ (as linked from https://github.com/profi200/open_agb_firm ).

If you're playing a GBA game, open_agb_firm or a VC inject are your best bets.

You could use open_agb_firm to play your GBA games instead.

Because unfortunately mGBA is a little bit laggy on the 3DS. It’s terrific for game boy and game boy color games, but I digress. You could use something like open agb firm which runs games using the 3DS’ built in gba hardware natively without any lag or slowdowns.

That shouldn't be needed — old versions of 3DShell like 4.3.1 have a built-in FTP server, so any computer, tablet or smartphone can use a FTP program to transfer the games onto the 3DS. You just have to pay attention to which folders you're putting the files into.

You have to click 'Releases' on the page, which bring you to this page: https://github.com/joel16/3DShell/releases

3DShell to navigate the filesystem

There is also an homebrew app, Screenshot Merge, that merges the two images into one, adding black borders to the 4:3 bottom screen to adjust to the 5:3 top screen resulting in a single rectangular image, that can also be easily viewed as intended (top image on top screen and bottom image on bottom screen at the same time) on 3DShell - both apps can be found on Universal-Updater if you have it.

Most probably you downloaded the beta (v5.0.0), which does not have FTP support until the developer releases a stable version. Uninstall it and then install this version (4.3.1), which is the latest stable one.
