I found this file:
Name: DevMenuAppPRODsmash.nsp
Size: 19578152 bytes (18 MiB)
CRC32: BB5CA85F
But when I try to install it with LayeredFS DevMenu, it stops directly (with error 0x0023e02) and with Tinfoil, it instantly crashes the OS (reboot required): I have barely enough time to see a message telling me that "cnmt.xml" is an "Invalid XML file".
I am on FW 4.0.1 with my current configuration and I have no problem to install/play any "commercial" NSP files. I also noticed that I don't need sigpatch to install/play them, only the ES SysModule override (0100000000000033) is mandatory.
Do someone have any idea why I get this problem when I try to install this DevMenu NSP? Is it incompatible with FW 4.0.1?
Thank you for your help!
