I wasn't expecting any issues since it's just a graphical hack.. well.. excluding the stand alone patch, but I hope you enjoyed the demo.
I'm currently in the process of using Yoshifanatic's disassembly to better organize my project since it actually includes folders containing all the games graphics. I've kinda been brute forcing it up until now by just editing the rom itself but that was extremely disorganized. Only the lost levels custom graphics had any organization until recently thanks to DarkSamus's custom lost levels graphic hack.
This will hopefully let me keep better track of what's left to do but I'll still have to insert everything manually since Yoshifanatic's disassembly can only assemble SMAS+SMW, and i'm currently not planning to make a SMW version of this hack.
Hopefully this puts the finish line just a little closer. Once the remaining sprites are finished, the main obstacle will be all the items in the list near the bottom of the first post in this thread. I know Stratoform made some of it possible recently but I've no idea how to actually impliment any of it.
Also I think I might want to re-open the poll about what this hacks name should be. I originaly pitched 35th anniversary edition but everyone voted for redrawn. I feel like now that Nintendo is actually celebrating Mario's 35th people might be more receptive to that name? I don't like to go back on poll results though, so i'm not too sure.
