PolyDumper and firebird emu on CX II-T

Hello, I am trying to create an emulation of the Ti-nspire CX II-T and used PolyDumper to get the needed files. However, Firebird emu needs different files and I don't know how to get them. I tried to find any idea online, but there was nothing about this topic. I also looked into the code of Firebird seeing that it supports the CX II-T model. Any help would be great. Thanks

Hello Mrbahnan,

emulation of Nspire CX-II is not possible yet for several reason, but the main one being the impossibility to dump/decrypt all files needed to correctly boot.
the boot structure and associated files changed between CX and CX-II and right now retro-engineering of the CX-II is not advanced enough to correctly dump the boot files of CX-II.

So far, there is no known way of dumping the 2nd part of the BootROM
(similar to the Boot1 on older TI-Nspire CX)
, the part including the keys.

No CX II emulation without this, which slows down the development of Ndless programs, which makes Ndless less popular and currently not updated for the latest CX II OS versions, which makes things worse... vicious circle. :'(
