First of all, this a superb work. One of my favourite improvements of one of my favourite Mario games!
Excuse me, but v.1.81 is not working with the 3DS Virtual Console. When this patch first came out (v1.0) it was working fine. I haven't tested any following versions, so I can't tell which one was the last to be compatible. I wanted to play with the late fixes.
Or, is it possible to download the previous patches? So I can try which one was the last to work. Thank you all!
EDIT: It's working! Problem was I had a bad ROM in my archives. The name matched, but not the MD5. Thanks again!
