Does anyone know whats new in the Mig Switch Firmware 1.1.9 as it's out! But the official site is down...

Firmware 1.1.9 fixes a Mig card issue for Mac users where hidden XCI files are inadvertently created by Mac OS starting with a dot. A long button press in such an instance could cause no ROM to be loaded. This is now fixed, and we wanted to push this update as it was annoying for some Mac users.

Site works for me.

So this would be useless for most people…but for those of us with modded systems what is stopping us from doing something like this to make rom hack carts pretty much ?


I’ve tried extracting and rebuilding an XCI and all the available tools seem to fail on the rebuild step, but if we can get past that point, and assuming the initial header still works (unless we can make our own or use a sys patch to ignore ?) our modded units should be able to ignore any other check and just launch the modded files, correct ?

it probably depends on if the gamecard reader firmware does its own checks too. the cfw doesn't reimplement that I dont think? on 3ds it works because only the os validates cartridges, but on switch the gamecard reader has its own firmware that atmosphere doesn't really modify (and I don't know if the gamecard firmware is even accessible from the os side, so it might not be possible to patch it either. and it wouldn't just be loaded in memory available to be patched either considering it's a different chip that handles gamecard reads)

it probably wouldn't be impossible to modify the gamecard firmware and install a custom gamecard reader firmware that would bypass all checks, but I don't know if that's documented yet. it would break the reader on ofw but you wouldn't care about using game cards on ofw anymore anyway

Even on a modded console all the checks of the cartridge are done by LOTUS device and CFW had nothing to do with it, so no possible to run modified cart even on a modded console.

@4d1xlaan was talking about the possibility of flashing the game cart reader's firmware with custom code.

the gamecard ASIC has its own bootrom according to switchbrew, that might be doing validation checks on the firmware independently of the main device boot rom, and if that's the case then even with cfw you wouldnt be able to just write a custom firmware and run it

we can't even bypass gamecard reader fuses either. or if we can, no one's done it yet, but I imagine that if we had a bypass then cfw would be including that, just for people who might want to use a downgraded firmware or who might have all the fuses blown somehow. I know malware could burn all the main fuses and make the console unusable without cfw, but I dont know if the same can be done to the gamecard reader fuses. but anyway

I bought mine from one of Mig Flash's listed resellers for $142 shipped. I am in the USA.

Ordered. Thanks. $143 USD

Mig sellers seem overly confident it will work with switch 2 lol

You can not "unlock" the switch console, only if is an unpatched V1 console you can use the exploit to run CFW, if not you must install a hardware modchip

He's talking about UnlockSwitch flashcart. Unless you're intentionally ignoring the existence of that flashcart? :D

It would be nice of them to finally release it. :D Even though I recently acquired MIG Switch, I wouldn't mind one more cheaper flashcart.

I'd be happy with some sort of clone of the dumper tbh, had my mig 2.0 since release but never really used the thing.... I do see advantages in dumping my own carts though but i'm not prepared to pay close to £100 for a dumper
