Great news, I was hoping you'd go on to do an MI2 Ultimate Talkie Edition. = )
If you're planning on fixing graphical issues like in the SoMI Ultimate Talkie Edition, I've got a couple here to watch out for:
-On Phatt Island, the creases in Guybrush's "WANTED" poster disappear once you've pasted Kate Capsize's brochure over it.
-Guybrush's shirt is dark grey while diving to the bottom of the ocean, rather than white like everywhere else.
