Encrypted, split iso does not launch

[throwaway652]

I have a fat32 formatted USB and inside it my game files are organized in the following manner:

/PS3ISO/game.iso.0
/PS3ISO/game.iso.1
/PS3ISO/game.key

The game.iso.{0,1} files are the disk original/encrypted ISO split using the GNU split program and game.key is the Redump decryption key.
The problem I am encountering is that when my files are set up in this way WebMAN launches the game into a black screen, sometimes freezing my console with nothing to do but shut it off with the power button. In troubleshooting this problem I have tried copying the game.key file to game.iso.{0,1}.key, to no avail.
My PS3 is on CFW,

If I recall correctly, the ISO decryption implemented in Cobra does not support split ISOs.

You should verify with Evilnat.
