The only actual change in .text was that only one function was updated. Right after the mediatype validation at the very beginning of the function, a code block was added for the functionality described below which is only executed on [[CONFIG_Registers#CFG_UNITINFO|retail]] units.

The only actual change in .text was that only one function was updated. This function only is called by [[AMPXI:InstallTitlesFinish]] and [[AMPXI:InstallTitlesFinishFIRM]]. Right after the mediatype validation at the very beginning of the function, a code block was added for the functionality described below which is only executed on [[CONFIG_Registers#CFG_UNITINFO|retail]].

Before installing titles, including NATIVE_FIRM, AMPXI will now check the version of the title to install against a hard-coded list of (titleID, minimumVersionRequired) pairs. This applies to  MSET, Home Menu, spider, ErrDisp, SKATER, NATIVE_FIRM, and every retail system module.

This AMPXI function will now check the high 6-bits of the title-version(major-version) of the title to finish-install against a hard-coded list of (titleID, minimumVersionRequired) pairs. This applies to  MSET, Home Menu, spider, ErrDisp, SKATER, NATIVE_FIRM, and every retail system module. When the title-version is invalid, this returns the invalid title-version error(0xD8E08027).

This effectively prevents downgrading.
