Recovering a NAND only with BOOT 0 and BOO1

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.

I think this is what you are looking for :

I am not sure whether you can use a NAND as a donor from a different model like the Lite in your case.

Chances of going online without problems are highly doubtful I guess.

i fix it with this guide:

you need to use the exact same version of NXNandmanager and Emmchaccgen that he used in the guide - links are in the video description.
