Ok i fixed this problem !!
here what i did : ( use the software Deltapatcher instead of the one from OP )
1- download DeltaPatcher (google it it's easy to find )
2- copy both the xdelta and the cia file in the Deltapatcher folder.
3-Open original file ( Sumikko gurashi cia)
4- open delta patch...
Good job for the translation amazing work so far ( still playing the episode 1 right now! ). Again Good job Uwabami and the whole team behind this project! it always impress me the amount of work just to translate one episode
yeah i implemented that -b in my python script but doesn't help apparently the problem is with the framebuffer adress they are integrated in the code so i don't really know how the new firmtool works since the readme.MD is not updated
so when we use the command line "firmtool build test.firm -n 0x23F00000 -e 0 -D mypayload.bin -A 0x23F00000 -C NDMA" this doesn't work because we need to change the 0x23F00000?
damn i think the problem is your path there is a space in it "/M. B. Reece/" can you change it to something without space and retry?
auto
Just put your Hourglass9.firm anywhere you want
