That logo is awesome, I even set it as my wallpaper!
ok here it goes, i thought it could take a little longer to get anything good, but here it is:
the 24bit bmp file is also available if needed
However..there's one thing, you have to set it up so it would look good on a shirt. Like make the borders white and so that it blends in, like a blob or something, circle, etc. You may have to crop the image a little, but it'll still look awesome. If you look at the mame logo that the guy made previously, it has white background borders to blend in. Also look at the Street Fighter 1Emulation Logo..they can all be found @ http://shop.1emulation.com
