I'm using MAMEWAH 1.6 and have the XVID codec. Where do I put the files once I have them?
You put them wherever you want, you just tell mamemwah where to find them through the mame.ini file.
What you do is assign movies to an artwork number (last line below), usually the artwork number you would use for your snaphots. When mamewah displays the artwork, it looks for a movie first, and if it can't find it it displays the static picture instead.
In my case, see below, my snaps are in d:\mame\snap and the movies are in d:\mame\movies and the snap/movie artwork is artwork1
### Artwork Locations ###
artwork_1_image_path d:\mame\snap
artwork_2_image_path d:\mame\marquees
artwork_3_image_path
artwork_4_image_path
artwork_5_image_path
artwork_6_image_path
artwork_7_image_path
artwork_8_image_path
artwork_9_image_path
artwork_10_image_path
movie_preview_path d:\mame\movies
movie_artwork_no 1
There are other movie related options in mame.ini such as how to mix movie sound, what volume to use, etc...
You can also use the movies in the screensaver, see that section and the mamewah doc.
Hope that helps.
