Good luck in university & hope you'll find spare time working on SMB someday...
I'm still working on Rohrleitung Gate, but progress has been very slow due to lack of ideas and loss of info I gathered before.
Are you now hacking SMB using NESASM?
Assembly is a convenient method once you get a high level disassembly source code, but if not, binary editing is still superior because of the branching & jumping destinations.
Hence I'm still using WinHex for editing...
(Crap. Now my English is getting worse, but I can't express all those in Japanese either.)
