I wanna see a MMNT/RMEXE Manga, And I can't find a site has it.

yeah its hard to find it well good lucks i found it once but they removed it

If you want some information on the manga, go to http://www.rockman-exe.com/manga.html
There are some pictures from the manga, too.
The page is generally good if you want to know something about the anime :)

I've got quite a few of the volumes but if you want to read it, go to a book store and buy it or read. Scanalations take money from the companies making these items, if I recall capcom gets a good percentage of the manga's money.
