What do I do with this???

[Big Rab]

Ok here's my problem......

I have the gameshark for my dc but as its a PAL system i have then u will know the probs that i am having with it i.e B&W Picture etc...
(I do have a working action replay Pal Demo version but it only has five older games listed for cheats)
So i got a hold of the ar-cdx.zip for the PAL system and unzip it to find the file....Action Replay CDX Dreamcast.
So What the hecks this then im thinking........
A nights forum trekkin reveals nothing about this file except that the ops or moderators are a bit sensitive on the subject.

Can sum1 please tell me what to do with this?

Now I have no clue, but do i burn this with the e-gscdx.cdi file to convert it to PAL or do I add it to the multisession when im burning the demo version which unlocks the other features of full release???
Or do I simply burn this as an ISO??? If so is there an audio file required like the demo version to get it to boot???

Any Kinda relative response would be great!!!!!!
