I'm darkly77 from NSMB-mods.com. I'm building a site that tells you how to hack NSMBw, with all the information in one easy to navigate place. I've made textures to play as Samus, Wario and Sonic, as well as skins for Classic Toad/Toadette and Giga Bowser.
I'm mainly writing guides at the moment, as finding a summer job and housing over summer break is taking up a lot of time.
I want your work. I've featured NSMB: Retro Remix on the site, and will continue to host information on new projects and developments.
Of course, making a presence takes time and requires content. but it's a start.
