There shouldn't be any reason. I always use hbl to launch everything, so I never tested a forwarder, but I don't know why it wouldn't work unless there's something weird forwarders do differently. Does it crash or just return back to the home menu?

Yeah ignore me... Typo should be my middle name

All good now and boots pretty fast too

Nice. Saves me the hassle of trying to track down whatever was causing that.

Don’t install cia

Tested metal gear solid: snake eater 3D, one of the most graphically demanding 3DS games.
seems to run fine on 1x with max OLED handheld clocks, more stable than on the actual 3DS. 2x resolution is just a slideshow.

i will test docked OC later and see if any improvements are notable.

Getting this many games near full speed on the Switch is seriously impressive. I'm curious how well suspend and resume behave

I'm not going to use it (no hate, I just don't plan to emulate 3ds on the switch as I have a 3ds anyways, and a gaming pc) but congrats to the dev for this

What do you mean? Like there's something broken with installing CIAs or you can't? Every one that I tried to install worked fine.

For reference, what are max OLED handheld clocks?

The Switch suspend and resume seems to work fine with the emulator. I've never had it fail to wake from being slept while testing different things.

You appear to have an encrypted cia then. You either have to give the emulator the keys, or decrypt it yourself. I don’t know the exact process for decrypting games since I just dumped all mine decrypted via gm9 on my 3DS.

For me it always aborts the cia installations. Maybe I transfer them to the original demanded folder and try again

Doesn’t work either.

Is there any error code that comes up when it aborts? Are they full games or updates/dlc?
