{{obsolete}} Patches NSP Files to require the minimum FW Version needed to decrypt it instead of any higher FW than that. ==User guide== ===What does it do=== It extracts NSP containers using hactool, patches them to require the minimum needed FW version of the corresponding minimum needed Masterkey Revision required for crypto and then repacks the NSP container using a modified build of rkk's nspBuild. See [https://gbatemp.net/threads/play-nsp-games-for-higher-firmware-on-lower-firmware-reinx-hactool-tinfoil-extracted-nsp.512921/ this thread] by Zocker4444 for reference. ===Summary of the keyblobs=== *'''1.0.0 - 2.3.0:''' **MasterKey Revision: 0. **Patching would achieve a 2.X.X game be playable on 1.0.0. *'''3.0.0:''' **MasterKey Revision: 1. **Patching would have no effect. *'''3.0.1 - 3.0.2:''' **MasterKey Revision: 2. **Patching would achieve a 3.0.2 game be playable on 3.0.1. *'''4.0.0 - 4.1.0:''' **MasterKey Revision: 3. **Patching would achieve a 4.1.0 game be playable on 4.0.0. *'''5.0.0:''' **MasterKey Revision: 4. **Patching would achieve a 5.1.0 game be playable on 5.0.0. ==Screenshots== https://dlhb.gamebrew.org/switchhomebrews/nspatchnx2.gif ==Changelog== '''v2.1 2018/08/04''' *Hotfix keygen detection.
