I would like to play good old Baldur's Gate once more, this time with the BG2 engine. Before I actually start playing the Tutu I just installed, I wonder - there is Tutu and there is BGT. Which one should I use, or what are each ones advantages/disadvantages? Does it make any sense to have both? If so, can they share resources or would that require all files and disk space to be there twice?
Is there a reliable way to include Icewind Dale too?
There is actually 2 different Tutu mods, there is the BG1Tutu(v4) and the EasyTutu... also I would like to say that you should never install the latest beta patch, it could brake your whole computers processing capability, as it contains ancient directX patches, and nothing up to date usable.
Now, it's your preference which(BGT or the Tutus) you wish to use, but in my opinion, I did a good comparison in
here. And no, I didn't give a straight answer, cause there isn't one, as the answer depends: How long are you going to play it, how many times, nd what other mods are you going to include, and do you want to have the 1 final mod that's made just for Tutu.
Yes, there was few questions in the link I left unanswered, but as you said, "Nevermind"...
Now, what goes to the programs sharing resources, they don't, but they can be copied from one to another, usually. So, the mods need to be installed to the game engine installation folder, meaning the place where they have a dialog.tlk and BGMain.exe or IDMain.exe. They all have the override folder, that is used to store the games modified files, and this is the place where the mod usually bring their modified files, so the game can use them.
WeiDU and DLCTEP though I'm not sure how to use them properly and whether I configured them correctly.
Well the WeiDU.exe in principle is just a renamed installation executable that runs the setup-*modname*.tp2's commands. So it doesn't need to be configured. Yes the setup-*modname*.exe is the same weiDU.exe if their versions are the same. And this is what the installation process always tries to make sure of, that all the exes are auto-updated to the latest version.
On the DLCTEP, you do have the .dat files from
here(the link at the bottom of the page in the link will make you to download the .dat files, so you can actually setup the program right), as they are needed.
