mgba VS open_agb_firm

VisualBoyAdvance is outdated, while not bad you can do better than that when mGBA exists

GBA emulator for PC: https://mgba.io/

Visual Boy Advance is actually outclassed these days, use mGBA instead.

Which game do you want to emulate? If you're talking about fe7 (localized as just Fire Emblem in the west), you're gonna need a ROM which I can't link here but I can PM to you if you need it, and an emulator. I recommend Mgba (https://mgba.io/) for GBA games.

Install the GBA emulator called “mGBA” on your 3DS (You can install it through Universal Updater or heres a link to it: https://mgba.io [v0.10.2] ) It should be a cia file to install through FBI.

no, you can use mGBA for GBA games, and MelonDS for NDS games

Here's the thread for the Real Battle Network Gameplay patch, here's the English translation patch, and here's the emulator I recommend where you can just slot in the Navi of your choice to unlock them immediately. The ROM you'll have to scare up for yourself, but I'm sure you can handle it.

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.
