No, ZDoomSRB2 was a total rewrite of SRB2 using ZDoom as a base. Unfortunately, I could not compile a working exe, so it didn't get anywhere and I lost interest...
doom1srb2.wad was a 1.08 wad, was it not? Are you trying to use it in 1.09?
Blue Warrior, feel free to take the zips and put them wherever you like. I totally disclaim all responsibility and liability for the zips, files contained therein, and that which happens as a result of your use of them. I make no warrenty, express or implied, that it will work "as advertised", if at all, and that it will not harm your computer, your SRB2 installation(s), your brain, your pet cat "fluffy", or anyone else whom you know and/or love. In short, USE AT YOUR OWN RISK. By doing so, you implicitly agree that you do so of your own accord and completely aware of the possible consequences and will not attempt to hold me responsible for your actions.
I probably put in a ton of "beta" wads in there, the authors of which didn't want to be officially "released" anyway, so if the torrent is dead and nobody's gonna put the files up anywhere, that'd make some person happy, I'm sure.
Yes, I suck at writing legal disclaimers, but I'm getting better... :(
