batteryless-patches VS mgba

This kind of cards are SRAM, but no battery. So just sram patch will do nothing. OP needs patches from this repo: https://github.com/acocalypso/batteryless-patches

If you’re able to do all that you can use this site for the patch. https://github.com/acocalypso/batteryless-patches/tree/main/patches/GBA/Pokemon

and https://github.com/acocalypso/batteryless-patches

Hmm, looking into it it seems to opposite problem actually. Aria of Sorrow already uses SRAM, but these carts only support FLASH. It seems what you need is a "batteryless patch", I found this repo but it doesn't seem to have that game, sounds like the best place to make requests is BennVenn's Discord, might be more in there too I dunno.

VisualBoyAdvance is outdated, while not bad you can do better than that when mGBA exists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

- mGBA repository

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.
