ROM Hack Need help extracting Tetris 99 patch V2.0 files

[appleb]

I'm trying to extract the files for Tetris 99 along with the V2.0 patch.
I have two files
v-tetris99.nsp (base game)
v-tetris99_v262144.nsp (v2.0 update patch)

I am able to extract the base game without issue using the following commands, so I'm certain my keys are okay:
hactool -t pfs0 --pfs0dir=output_nca v-tetris99.nsp
hactool -t nca -k keys.dat --titlekey=44xxxx00 --romfsdir=output_romfs output_nca/cc0d3c145987b75b18ec84f37b9f362b.nca
This works fine and i am able to see the files in output_romfs

But when using the the same command to extract files from the update:
hactool -t pfs0 --pfs0dir=output_nca v-tetris99_v262144.nsp
hactool -t nca -k keys.dat --titlekey=2CxxxxF2 --romfsdir=output_romfs output_nca/4902e99a47f2f5d3ef468abad1a52367.nca

i get this error:
BKTR section seems to be corrupted.
Error: section 0 is corrupted!
Note: cannot save BKTR section without base romfs.

Can someone tell me what I'm doing wrong? My main interest is just getting access to the bfstm music files in the update.

Update doesn't contain files. It contains diffs.
So you need to make plaintext of Program NCA from Base and use it as --basenca for update.

Hmm, well I tried this...

hactool -t pfs0 --pfs0dir=output_nca v-tetris99.nsp
hactool -t nca -k keys.dat --titlekey=44xxxx00 --plaintext=newbase.nca output_nca/cc0d3c145987b75b18ec84f37b9f362b.nca

hactool says "Saving Decrypted NCA to newbase.nca..." and I get a file of size 152,846,336 bytes, so that looks okay up to here.

Then trying to extract the update:

hactool -t pfs0 --pfs0dir=output_nca v-tetris99_v262144.nsp
hactool -t nca -k keys.dat --titlekey=2CxxxxF2 --basenca newbase.nca --romfsdir=output_romfs output_nca/4902e99a47f2f5d3ef468abad1a52367.nca

The second line gives me the same error as before...
BKTR section seems to be corrupted.
Error: section 0 is corrupted!
Error: section 1 is corrupted!

--basenca=newbase.nca

--basenca=newbase.nca

I appear to be still getting the same error =(

hactool -t pfs0 --pfs0dir=output_nca v-tetris99.nsp
hactool -t nca -k keys.dat --titlekey=44xxxx00 --plaintext=newbase.nca output_nca/cc0d3c145987b75b18ec84f37b9f362b.nca

hactool -t pfs0 --pfs0dir=output_nca v-tetris99_v262144.nsp
hactool -t nca -k keys.dat --titlekey=2CxxxxF2 --basenca=newbase.nca --romfsdir=output_romfs output_nca/4902e99a47f2f5d3ef468abad1a52367.nca

output:
BKTR section seems to be corrupted.
Error: section 0 is corrupted!
Error: section 1 is corrupted!

I think i'm almost there... probably something silly missing.

Try to delete

 -t nca

take --titlekey after --basenca

If still is not working, then NCA is wrong or you have outdated keys.

I finally got it working using these two commands:

hactool -t nca -k keys.dat --titlekey=44xxxxxx00 --exefsdir=exefs --romfsdir="romfs.bin" base.nca --plaintext=NCAID_PLAIN.nca
hactool -t nca -k keys.dat --titlekey=2CxxxxxxF2 --basenca="NCAID_PLAIN.nca" --romfsdir="romfs.bin" update2.nca
