Hacking Emulation Hackroms on Nintendo Switch Online?

[Misterfan2000]

I wanted to know if it's possible to patch the roms included in the Nintendo Switch Online games (NES, Super NES, GB/GBC, GBA and Nintendo 64)

If it's possible, how it can be done?

If you install CaVE Database Manager, many custom roms, including hacks, can be added to the Nintendo Switch Online apps: https://gbatemp.net/threads/cave-da...n64-genesis-switch-online-modding-app.551466/

Worth noting that not all of them will work with Cave. I have several installed and found only one instance of this though.

I tried using CaVE Database Manager to replace Super Mario All-Stars and Super Mario World roms with hackrom ones, but it crashes the app

Anyone has a solution for this?

You need to install a mod called "full unlock" for SNES app and then convert the ROMS you import to the sfrom format, see here for the whole process. All the tools are listed and there are step-by-step tutorials: http://darkakuma.z-net.us/p/cave-database-manager.html

Not all of them, but I've got plenty working, namely color hacks for Game Boy games.

Most of mine are for the SNES, with the exception of the Mario 64 splitscreen multiplayer mod which I highly recommend
