Gave it a spin, I have two things:
Nitpick, but shouldn't Vacations be singular?
Also, I got a black screen after hitting start on this part. For the sake of ruling problems out, is the patch for headered or non-headered?
Thanks for the feedback!
Now to your questions:
1) I am really unsure about this.
I know in spanish (my native language) it is always plural, no one says it in singular, so I might be confusing it in some form, I need to investigate that.
Edit: I believe it is singular in English, I will do some research and change it accordingly if that's the case.
2) The patch (TranslationGamma) is for an unheadered ROM.
I believe the base ROM is "Mario Wrecking Crew 98.smc" from a lovely ROM site.
Try removing the header from the original base ROM, then patch it again and see if that does it.
I will be releasing patches for both headered and unheadered ROMs once we get to the end.
