Can't run DS carts or TwiLight Menu on 3ds

[Aphixe]

So if I run sysnand i can load ds carts but I can't do it in Reinand. I listed my version below. I'm sure i'm running some old versions of firmware, but i'd like to keep my sysnand untouched because i have another flashcard i use as it doubles my sdcard storage.

This is the error i get running ds cart or twilight menu in cfw. only fix i see people say is to update the firmware. after i run some file TWLFix-CFW.. is this my only option?

An error has occurred. Press and hold the POWER Button
to turn the system off. Please refer to the
Operations Manual for detail..

versions of system
ReiNAND 11.2.0-35U
SysNand 9.0.0-20U

That may be your only option. I personally know of no other way to fix missing files in the twl.

I'm sorry I realize you have your preferences but the best advice you're going to get here is to update to a more modern CFW, I dont know what flash card you're trying to preserve use of but I can tell you with modern CFW you will still be able to use it. even if it's something outdated like gateway you'll just simply need to set up a dual boot environment on your 3ds

its gateway. I just don't know how to set it up. I just don't know if i i need to update my sysnand

I don't believe it's your sysnand then that needs to be updated as you said you can load DS cards from sysnand but not when actually running your CFW meaning your CFW is likely to blame hence my suggestion to update your CFW

As far as preserving your gateway you're going to need an emunand to use with it and this guide https://gbatemp.net/threads/tutorial-using-luma3ds-gateway-on-b9s.431691/post-6466799
