Since the very first day I played it, something has bothered me about SMAS’s version of SMB (and Lost Levels): when Super Mario smashes a brick, he doesn’t rebound properly. In fact, if he hits a brick at the peak of his jump, he’ll actually be pulled upwards into the brick! (I find this kind of odd, since the games are just heavily modified versions of the original NES code, for the most part.)

Anyway, I got bored the other night, and decided to track down the problem and fix it once and for all. It was actually much easier than I thought, just a case of reversed Y velocity…silly Nintendo.

These patches will correct the brick behavior in both SMB and Lost Levels, and also add the missing “thump” noise.

Note: The hack can be used with the Super Mario Bros 1 SMAS - NESised hack, but you must use a non-headered ROM and apply the non-headered compatible version of this patch. Then apply the NESised hack patch to that same headerless ROM. Or you can do it the other way around (NESised first, then brick patch), it shouldn’t really matter.
