RomPatcher.js VS mgba

You need to patch your rom with the translation patch. On PC there's offline patchers, but using something like https://www.marcrobledo.com/RomPatcher.js/ is probably easiest on mobile.

In that case, you're gonna need a ROM, an emulator (https://www.zophar.net/snes/snes9x.html), a translation patch (https://forums.serenesforest.net/index.php?/topic/63676-fe4-translation-patch-open-beta-v7/#comments), and a patcher (https://www.marcrobledo.com/RomPatcher.js/). Theres different patches for different versions of the game, but the readme in the translation patch tells you which patch to use for your file.

Do you have a 3DS or PSP? I hacked mine and it’s really convenient to play old games on. There’s lots of homebrew tutorials on YouTube. For those games you need to put a translation patch on the rom (I usually use this website to patch stuff). Or sometimes you can find a rom that someone already patched. All this might sound complicated, but trust me it’s not. I barely know anything about computers and this kinda thing, but I figured this stuff out.

I usually get my patches from Romhacking.net, and they specify which ROM you'll need in the the ROM / ISO Information section in each page. For patching, I use Floating IPS. You just need the .ips patch and a copy of the right ROM. You could also use online patchers, like the one over at www.marcrobledo.com.

I then loaded the ISO.file with the latest patch 2.0.31 https://ffhacktics.com/smf/index.php?topic=12767.0 with the help of the following website https://www.marcrobledo.com/RomPatcher.js/

You need to patch it first with a clean emerald rom (Emerald.gba (Trashman)) . Using https://www.marcrobledo.com/RomPatcher.js/

VisualBoyAdvance is outdated, while not bad you can do better than that when mGBA exists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