It will get you on the right track. Regarding your aspect ratio, the Mazzlefier will usually autoselect the correct aspect ratio (almost all CRTs are 4:3)
You need the
Mazzle 1.1 Core and the 2 packs by DeTard:
-
DeTard's WoW 2.3 Add-On Pack for MazzleUI
-
DeTard's Mazzle Fix
Be sure to read the information on the DeTard's WoW 2.3 AddOn Pack for MazzleUI page as it contains a lot of info on troubleshooting potential problems. I would advice printing the page so you have it handy.
Once you get MazzleUI installed and setup, you can access the MazzleUI FAQ via the little "M" button above your shiny new consumables bar (the buttons with your potions and such). It contains all the info you need to know regarding the mods in Mazzle.
