RomPatcher.js VS EmuDeck

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/

You could look up their Cheat Sheet so you know what BIOS you'll need

INSTALLATION: To install this software go to dragoonDorise/EmuDeck: Emulator configurator for Steam Deck (github.com) or EmuDeck - Emulators on Steam Deck, SteamOS , Rog Ally and Windows to download the software. If it downloads to the downloads folder, make sure you move it to the desktop in order to run it. When it runs it may ask for a sudo password and if not then just follow the on-screen instructions it's pretty simplified so no need for additional walkthrough.

My thoughts after reading your post: 1- Go to steam desktop mode and reinstall emudeck. It will take a few minutes and you will be sure that installation is ok. 2- You can find the extension of the roms that can be read by Emulation Station in this post: https://github.com/dragoonDorise/EmuDeck as a rule of thumb older games can be left zipped while newer need to be unzipped. Good to check in any case. 3- You can follow another tutorial, but the one of retro game corps is the one I followed and it worked... Please, let us know how it goes.

Download this, https://github.com/dragoonDorise/EmuDeck and when you install it, it’ll give you a button to sign up for the patreon.

Emudeck Cheatsheet explains which systems need bios, what the file should be named, and where to put it.
