Playstation underground demo discs

[Psychotisis]

Picked up 2.2 and 2.4 both in great condition. Anyone got info on these? I can post pictures here in a few. Just wanted to get the info ball going while I'm here in subway.

I recall seeing a couple of these in my old junk a few months ago. I think that they were some type of subscription service, or maybe even an inclusion with a magazine subscription from the early days of PSX. I dont ever recall paying for any type of subscription though :/

They came free with these magazines:

Could get similar in the UK from Official Playstation Magazine. I've got a few kicking about. Not really worth anything though, as far as I know xx

Oops, scrap my previous statement. The discs actually ARE the magazine. The first disc has all the typical magazine shit on it, as well as other stuff.

Only 17 issues were released then they were bought over by OPM. It says it all in the Wiki link :) xx
