Well, Jamie has Integrate GOTZ already into V0.45 of GOTZ, now this mean, from what i last heard form him you should jsut replace his SMRTER Main-Menu Script file with the GOTZ one, hopefully with no strings attached or issue THIS MIGHT Work, that means GOTZ-SMRTER v0.45 wont need a merge patch, or alot of intense work. So ya, on the other hand MISERY is so far Still Unpatched due to its major change in code, and inability to find anyone who knows the Code.
UPDATE - 2013
Now many people have commeted/pm'd me about helping that is very very good cause me myself cannot do much of this alone as I'm really unfamiliar w/ the aspect of the coding and etc.
Now onto Compatability News
Misery 2.0 has been released so if you havent downloaded it do it now they put alot of effort into it and it is really great mod. I'll see what i can do for having someone either form the misery team, or who can familiarize themselves on the modded elements of misery so that the files in GOTZ can be successfully merged and working.
As for SMRTER idk the creator has had internet and computer troubles so now at this point the mod is in indefinate hiatus which means unless he revives it or someone manages to use the work from v41 to recreate all of his work and etc into a modded version of the mod then we'll probally remain waiting forever until he returns. Now as for other mods i'm not really looked into as so far MISERY and SMRTER are the 2 projects i follow personally, and SMRTER comes w/ GOTZ support all that has to be done is replacement of the main menu script files so if a V45 release is shown and we are graced it will have GOTZ support and as for the other Mods I would suggest their respective Owners/Dedicated fans/Project Member/ETc recreate their coding and merge the appropriate files creating a Compatibility Patch for the 2 Allow GOTZ to be used w/ the Mod
