Dark_AleX has done it again.
He has released the Homebrew Enabler 2.71 Revision D ( HEN-D )
The download is with an included Devhook-Version.

Here the Changelog for HEN-D :

- Revision D (25 November of ******* year 2006)

Fixed a bug in a patch bad done in a delay slot that caused some umd games not to work when HEN was
running (this issue was fixed in SE before)
Fixed a bug in the loading of big user prx's, that affected a plain prx of socom2 umd, and some
homebrew prx's.

Bypassed a crappy $ce protection that prevented the umd to be mounted if the application was run from
the memory stick

Usb mass storage couldn't be loaded by homebrews in non-devhook version because semawm.prx is sign checked.
HEN now applies the algorithm to reverse the sign check, letting this and the rest of firmware
modules to be loaded by a homebrew.

Added a SDK for HEN/SE.
