This version contains a major change in the way it works: the chainloaded application will need to elevate its own privileges using SVC 0x30 (a stubbed SVC on retail firmwares), which is an alias for SVC 0x7B (svcBackdoor).
Most retail applications (including dlplay) have access to this.
This was agreed upon with @nedwill and @d3m3vilurr in order to ensure compatibility for future homebrew.
_For developers_: please refer to this.
