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.

hi guys. my first thread in this forum. if it's wrongly placed, feel free to delete or move to another topic.

a friend of mine modded my switch oled with picofly kamikaze method. everything works like crisp and i read a lot and watched a lot of videos and i understand more and more.

but i got one last problem to solve: when i install switchgames via tinfoil everything works perfectly except for a few games. but when i install emulated games from snes or gb from tinfoil, it installs the game successfully, but when i start it from launcher, it doesnt start and i come back to the launcher. that is the case with every emulated game.

i feel like there will be a simple solution, but i cant find any source for it.

i have retroarch installed via homebrew shop. i looked in the sd card and it downloads the game.

what do i have to do?

i would be very thankful for a solution.
