Tutorial  Updated

Setting up Android with EmuMMC + bigger FAT32 partition.

As the title says, here's the video; I'll do a write up later since it's a long process.



This is not possible in windows 10 due to the GPT Hybrid MBR trickery used, the android image already does this when it writes the partition tables and etc.

Don't do this in windows nor attempt it, it's not going to happen unless there's something you can use to mess with partitions like I did, L4T-Ubuntu also won't work due to the partition stuff and etc, I'm currently making something to allow this without any complications, please be patient!

Watch the entire video and you'll understand more about this, if you make simple errors from not watching the video I will simply tell you to properly watch again and listen!
TOOL ETA: Don't ask, it's a complicated tool that needs a lot of maths, safety features and etc
TOOL SO FAR:
EBa_eq9XUAMnNN5

Tool functions: Android, Custom Android user data, 8GB Android install, Ubuntu, Ubuntu Swap, EmuMMC and Lakka dynamic setup.
Planned functions: Multi EmuMMC setup, EmuMMC Backup & restore(including Nintendo folder) + More unique management stuff!

UPDATE: I'm currently setting aside the tool until I finish making & releasing my new modchip

I get about 17-19 MB/s on the card I just linked (writing NSPs), but I think the laptop I use is the bottleneck. Seems like it's a good value for the switch, but if you are willing to pay a premium, you could push for faster. I think I will upgrade the card when prices drop again. But so far I am having a good time with it.

This is a review of the specific card. It's said that Nintendo recommends cards with a read speed of 95mb/s, but I don't yet know its potential:

Sequential is good, and random is bad. For game performance, it ought to be good. Maybe for some OS aspects, it could leave room to be desired for.

I know that this is just more than $30 more expensive, but I swear by this. It's your best value of GB/$ and it's a lot to work with if you are thinking about multi-boot/emu-firmware

Well atleast for my case I only plan to run Android and a stock SwitchOS, no CFW of any kind and currently I have 32gb card in that isn't even half full since I buy all my games physical sans Smash and Indies.

Sounds like you wouldn't be disappointed with whatever you get, as long as it's bigger. Perhaps UHS-3 is the best option, in general... but depending on the brand/line the benchmarks go all over the place. For example, the Sandisk UHS 1 has comparable rates to the Samsung Evo UHS 3. If you are interested in researching, there is a ton of info.

@TariqSoftDev So I’m still waiting on my emmc chip. Do you think this tool you are making could write directly to the EMMC as well? I haven't taken the time to review how to repartition the EMMC, but in windows it looks like you can mount some emmc partitions and write to them. Wonder if this could be tied in. I’m going to experiment with booting android off the emmc itself eventually.

I don't really have the money to be experimenting with larger EMMC chips; if people really want that(even ubuntu off EMMC), if I ever do then I'll write up a guide how to do it although I'll prolly make a cheap box in which you can plug the EMMC in and then R/W on it.

If this is another feature anyone would want I'll make a EMMC PCB with sockets.

Hmmm, I was thinking that this could be done from the switch itself.
Check this guide out - Https://pascoe.pw/2018/09/switchnand.html

I think you can mount the EMMC from Hekate?

I only ask about this because I’ve ordered a 256gb EMMC chip that I plan to play with.

Mhmm I knew that method already; I'm just a weirdo who likes niche things that can be done better. :D

Hah. Yeah I would probably buy an emmc reader too just to make it easy to write to. Just wanted the chip in hand first. It came from east asia lol. Delivery is by freight so I’ve been patiently waiting.

I want to see what it would take to boot android off the emmc and I haven’t gotten a chance to edit the boot.scr for android. Do you think that would be enough?

Awesome. Well I can definitely be the guinea pig for a program that writes to the EMMC. :creep:

May be a corrupt image or so.

You say you got a 16GB card right?, if you want to help me with some testing on my program lemme know and I'll PM you my Discord

That got my attention. Don't tell me you're working on a way to have two SD cards in the Switch and a switch (lol) to jump between them between every boot because that's exactly what a friend of mine and me were looking for when Switchroot Android came out but the only kind of adapters we stumbled upon either were not flexible (so a long plastic bridge would stand over the edges of the Switch's housing) or it was only an adapter to use multiple SIM cards and one micro SD card inside a mobile phone slot. :D

    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages

  • The Real Jdbye @ The Real Jdbye:
