Total_Noob released another update to his HEN.

this added:

- Added online gaming support.
- Added server for TN NETWORK UPDATE.
- Fixed bug in VSHMenu where CPU speed hasnít changed when set it to default.
- Fixed bug in Digital Comics that caused a crash.
- Fixed server redirection.
- Removed FAKE INDEX.DAT from VSHMenu, but feature is still effective (move version.txt to X:/seplugins/).
- Signed HEN with prxEncrypter (thanks to Mathieulh, bbtgp, coyotebean, kgsws and everyone who involved to this project).
- Used Daveeís $v1 trick to find power_buf_addr.
It is signed, meaning it can be run from the XMB (menu) without need for the HBL.
