SUPER MARIO BROS. 3MIX

What it is:
A major overhaul hack of Super Mario Bros. 3 using the Southbird (that's me!) 2011 Disassembly.
Currently released is Rev 2B! (2/24/15)

Download:
You can download IPS patches for USA Super Mario Bros. 3 ROMs, both PRG0 and PRG1 varieties. I used Lunar IPS to generate these, and you should use it to apply them.
NOTE: After patching, verify your file's MD5sum is 4c7960cb6aa162ae2160fb111c3e4d92.

Starting fresh? Use these:

Download Rev 2B PRG0 IPS (e.g. Super Mario Bros. 3 (U) (PRG0) [!])
Download Rev 2B PRG1 IPS (e.g. Super Mario Bros. 3 (U) (PRG1) [!])

Upgrading from an existing version? Use these:

Download Rev 2 to Rev 2B Upgrade IPS (upgrade Rev 2)
Download Rev 1 to Rev 2B Upgrade IPS (upgrade Rev 1)
Download Rev 0 to Rev 2B Upgrade IPS (upgrade Rev 0, formerly "1.0")
