Cannot mount Super Smash Bros. Special Demo Version (eShop Demo) #69

Closed LolHacksRule closed 3 years ago

LolHacksRule commented 4 years ago

When I try to mount Super Smash Bros. Special eShop demo (USA) as a decrypted 3DS file (MD5: 8E18F555182E42B524DBA8A6FC9C5462), I always get this error.

Failed to mount ExeFS: InvalidExeFSError: Failed to convert name, probably not a valid ExeFS Failed to mount RomFS: InvalidRomFSHeaderError: Length in RomFS Lv3 header is not 0x28

Other archive viewing software like Toolbox opens it fine. Any advice?

Does GodMode9 handle it correctly? My first thought is that the crypto flags in the NCCH header were not fixed, which happens when using legacy (i.e. ancient) decrypt tools.

It probably should, testing rn

GM9 outputs

invalid directory object

when trying to navigate to exefs or romfs directory.

Verifying mentions

bad crypto flags

trying that rn

UPD: That fixed it
