I have Rogero 4.46 Cobra 7.0 and i wanna stay on this CFW

Until now i did the following steps:
- create a new empyt file in HEX Editor.
- copy the values into this new file (just for example 3D 00 00 00 1B 43 00 00 4A 00 00 00 00 00 00 00 in case of Baldurs Gate)
- save the file (CONFIG.DEC)
- open Ps2 Classic Gui
- encrypt the CONFIG.DEC for create a CONFIG file.
- Copy both files to the Ps2 Classic right place next to the encrypted iso (with Ps2 classic manager)
- Launch Ps2 placeholder
- I got black screen
I tried the other method too:
- create a new empyt file in HEX Editor.
- copy the values into this new file (just for example 3D 00 00 00 1B 43 00 00 4A 00 00 00 00 00 00 00 in case of Baldurs Gate)
- save the file (CONFIG.DEC)
- copy the PS2 iso into the internal Ps3 HDD PS2ISO folder
- i placed the CONFIG.DEC into this folder next to the iso
- rename the config to baldur.iso.config. (so i have BALDUR.ISO and BALDUR.ISO.CONFIG)
- run the iso from multiman
- the games runs but the background textures are the same: glitchy.
What did i wrong?
Can you look at the config file what i created and uploaded above?
