Hacking Secondary emuMMC with different format.

[Glendor]

Hi,

Im new over here.

I’ll introduce my case:
Actually, im having a Switch OLED with a Picofly chip installed and i have all hekate and the emuMMC with Athmosohere in a 256 Gig sd ovrr exFat format.

I only have a main partition, so the emuMMC was done using the “SD File” option on hekate when creating the emuMMC.

On that one, im installing my current nsp,xci files etc… but now, i badly want to emulate som GBA games and i read about RetroArch, but the point is that my sd is on exFAT format, and this seems to be a problem.

Now , my question is :

Is it possible to , first backup all my sd files on my pc.
Then, create a raw partition with 32 Gigs and format it to FAT 32. After that, restore my backup files on the bigger partition and then create a new emuMMC on that 32GIG FAT32 partition and use it only for retro arch ?
I know that i probably will need to modify the .ipl to declare this new emummc boot option, but honestly i dont know if just restoring the backup files from my actual situation will work… please guys give me some light over here regarding this.

Appreciate it <3

Regards.

If your emu is files based Just backup your sd, format to fat32 and restore your backup.

Hi, tx for the reply.

The point is that i want to have like 2 emmuMMC at the same time starting from my non partitioned SD card.

So i want to have mu current emuMMC on one partition (exFAT) with everything i have now and then another smaller partition (FAT32) with another athmospgere setup just to have RetroArtch there.

Is that even possible ?

And if so, ho do i manage to do it ? I guess that starting from a empty SD only with hekate and exFAT format, i can then create a raw partition from hekate ( im assuming that this option creates a FAT32 partition, idk ) and then, restore the ssd backup on the sd file and create a emummc on the partion i created. And then on that partition just install athmosphere and from there just put the RetroArch.

Im i correct ?

Yes and no. There's really no reason to have more than one exFAT/FAT32 partition on your microSD card, and in fact I'd discourage you from using exFAT at all. Having multiple emuMMCs is not a problem, but the problem is that Horizon OS will read the first exFAT/FAT32 partition it comes across, regardless of which emuMMC you boot. There's really no reason (that I can think of) to have a dedicated emuMMC for RetroArch. I DO think you should check out Lakka for Switch. It's a Linux distro that's pretty much dedicated to running RetroArch.

If you really want to set up two emuMMCs, I'd follow this tutorial. Note that in this example, they're both partition-based, not file-based. Which in my opinion is the better way to go. In any case, both emuMMCs share access to the same FAT32 partition.

Thank you @RHOPKINS13 , i think i would check on Lakka instead of messing something going with the dedicated emuMMC option.

I would consider to switch my current emuMMC file based to a partition, as you suggested its a better way to go.

Thanks for the help mate.
