Is it possible to make Switch-managed dirs/parts inaccessible to homebrew?

Dekopon - (Mostly) Fullspeed 3DS Emulation on Nintendo Switch

PalindromicBreadLoaf · 2026-07-16T19:11:42+00:00

Credit goes to StickyMangoRice for the logo. Dekopon is a port of Azahar to the Nintendo Switch. The current release is version 2.2.1. Performance is very title dependent, and will be improved with time, but many games can be played fullspeed right now, sometimes even with stock handheld clocks. (I do recommend at least bumping the CPU up to dev unit clocks in handheld just to reduce shader compilation stutter and smooth out some rough frame pacing.) Depending on the game, you can get up to 4x resolution scaling at full speed in docked/handheld charging (although really 3x is all you need in handheld). If you want to try any new3ds exclusive games, they won't run well. All four of the 3DS' cores run on a single emulation thread, so we're at a 1.2GHz difference (2GHz single core where as the 4 3DS cores each run at 804MHz) from what we would need (and architecture changes from 3DS to Switch cannot account for that much raw clock speed loss). The solution would be to split the emulation threads on new3DS games, but that's a ton of work for very very little gain. See here for a full compatibility chart: Dekopon Compatibility Chart Feel free to share your own compatibility findings here and I'll update the sheet accordingly. Also share any issues you have and I'll do my best to fix them. Downloads can be found here: Releases Along with the source code here: Source ROMs default location is /switch/dekopon/roms/ All formats that Azahar natively supports are supported here too. Different screen layouts can be cycled through via pressing the right stick. Pressing '+' on a game shows information about it, including updates and dlc. Enjoy! Also if someone wants to make a better UI for this I wouldn't be offended. I can't make a good UI to save my life, but the one included at least kinda functions to get you into a game.

Using both sysMMC (online) and emuMMC (offline), I've encountered a few examples of homebrew being dangerous in regards to causing accidental bans. Tico immediately comes to mind, as I recall that it prompts to make a forwarder on first run.

I know that installing anything without sigpatches active will result in an error, but wouldn't merely the act of attempting to install something get logged too?

Is it possible to prevent accidents like that? I'm thinking it could help if some Switch-managed directories or partition were made read-only to homebrew somehow, since only some (e.g. Sphaira) have the means to prevent accidents like this.

As for a quick hack, I found that using Sphaira as the sole homebrew launcher and using its "hide" homebrew option to hide NROs that are risky to run, then making a forwarder in emuMMC/offline install should be a decent way to prevent accidents.
