I also will take exception to your question about exiting the VC games.
PCR20 is correct in pointing out that this has been asked and answered several times in this very thread.
Insulting people here is not a good way to get help.
Take the time to read through this thread and you will see (as PCR20 said) the answer is here.
As for your comments about Triiforce not reading the wads and extracting the PNGs, the proper place to ask for future version enhancments/suggestions is on the Triiforce Googlecode site.
