A new Super Mario Bros. demo is up! http://www.d.umn.edu/~lscharen New features are: 1) worlds 1-1 to 1-4 are not (not 100%) 2) 10-20% faster on unaccelerated systems 3) vertical flipping 4) more stable code 5) smaller file size 6) switched from PEI to PEA based updates There are a few obvious bugs and cosmetic problems, but, hey, it's alpha software. Enjoy! -Lucas S.
