I have another bad news, apart from the found CD content that was uploaded few months ago, the designer who had it had another harddrive with much more of the stuff and more recent, the CD backup was abysmal compared to that and didn't have much new, apart from some different map versions and stuff and of course the UPSX patcher.
But it seems the harddrive was fried, so nothing is there anymore...I guess the missing maps need to be remade from scratch then, as there is no other hope recovering the stuff, apart if someone managed to contact Jeff Rubin or Jakub Kisiel, which are the only designers that I have not contacted, well I contacted two Jeff Rubins, but these were not the ones I looked for.
this is NOT the one btw:

So if you wanna help don't contact that one.
I suppose Jakub Kisiel was this one:

Although not sure, the one that worked on Unreal PSX had an account on one unreal related site, i think Unreal destination or how it was called. Maybe I am confusing the name now, but his old email on that doesn't work of course. EDIT: Nvm it was unreality.dk, the site
I tried to contact people can fly for his contact, but they didn't get back to me. All of the other designers I contacted before though, well Jason Watkins didn't talk to me for a long time and he supposedly still had some of the stuff, so I dunno about that, if he will ever get back to me again.
