You need to install the second cia in /_nds/twloader/cia

Both, as said in step 3.to emunand or system?

Sure, here : https://3ds.guide/can you link me to a guide for arm9loaderhax? i was using rxtools for the longest and finally figured out how to load luma.
I got a question, I have a DSTT with no microSD card.
Can I use the DSTT flashcard to play my backups from my 3DS SD card?

You can run your backups from your 3DS SD Card, no flashcard needed.I got a question, I have a DSTT with no microSD card.

It's practically useless without an SD. Even though I (personally) would get an SD card, and wait until playing games off the SD is a little more polished...I got a question, I have a DSTT with no microSD card.

Install "TWLNAND side.cia" to NAND, hence the filename having "NAND" in it.last thing, do i install the sys.cia to sd or nand. im trying to install to sys but the install keeps failing.

Install "TWLoader.cia" to SD.same process as gba correct?

Try launching a game in TWLoader.alright, i installed the twlnand.cia into the nand of sys and the .cia to the sys side of the sd as well as the emunand sd. is this what i'm supposed to do?
Install "TWLoader.cia" to SD.
Install "TWLoader - TWLNAND side.cia" to NAND.

Did you install "TWLNAND - TWLNAND side.cia" to the NAND destination in SysNAND and EmuNAND?still having the same error...
Can you launch any DSiWare or DS Download Play (outside TWLoader, of course)?Sorry for being noob here, Can you please point me to the correct direction here. When I check TWLoader - TWLNAND side title in FBI it Shows NAND, so I suppose I installed it correctly and everything else. However, when I start a game, it just gave me black screen and my 3DS froze. Any advise?
Thank you.
