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.

smas_brickfix.ips (for SMAS)
smasw_brickfix.ips (for SMAS + Super Mario World)

These patches will correct the brick behavior in both SMB and Lost Levels, and also add the missing "thump" noise. Make sure your ROM has a 512-byte header before applying a patch!

Enjoy!

I knew those games played differently on the SNES compared to the NES. Does this affect anything else in the game as well (was that property associated with anything else that caused it to mess up) such as Mario and Luigi "floating" a bit after jumping on an enemy (the spring from it), because that was the major difference that made the SNES version so much easier.

Oh, I'm going to get this patch.

I checked, and it doesn't seem like it.

Good job on this, BMF. The physics differences between the NES and SNES versions of SMB always annoyed me, so this patch is good.

I downloaded two known good dumps for SMASW from two sites and the patch didn't work on either of them. You may wanna look into that.

The SMAS patch worked great tho. I haven't really been able to put my finger on what was different about the game. Now it feels alot more authentic to the NES original.

I thought they both the same unless both of the roms are different.

Yet another reason why BMF rocks so hard. Now, all we need is a special case to handle world 36, since obviously the original code would not produce the same result on the SNES (since it didn't on FDS either).

I also noticed that, after applying this patch, some of the other SMB glitches seemed easier to do (for example, the hat stomp). I don't know if that's a function of the code, or if it's just the placebo effect, but it definitely makes both SMB1 and SMB2j much more enjoyable in SMAS.

It'd be interesting if Nintendo were to use this patch for any possible releases of SMAS over Virtual Console. I'm almost certain that Sega has borrowed some of the bugfix patches that the Sonic scene has made, so it's not unheard of.

I wouldn't be surprised to see them fixing bugs, but for something that changes the game mechanics, they'd probably want to leave it, lest people complain that it's not quite the same as it was on SNES.

I would just like to say that I love you for making this.

And now I will go play All Stars, and be happy about it.

I guess I complained enough about it, and now I can actually enjoy this game.


EDIT:
So, I just beat the original Super Mario Bros. on this the second time through in a row with 13 extra lives.

And I must say, it is enjoyable due to this patch.

That didn't stop them from changing it in the first place for the SNES release =P

Cool stuff, I never paid attention to that bug...

By the way, I can only get the smas patch to work. The smasw pach corrupts my ROM, and SMB1 fucks up and freezes after 1 second.
And I redownloaded both ROMs just in case...

That's...really odd. I just tried it again last night, and it worked fine. Maybe I have a different ROM version?

Could you give me some info about your SMAS ROM? Specifically, the GoodSNES name (if applicable), the filesize, the checksum, and whether or not it has a header.

Sorry about that, it turned out my ROM didn't have a header.
As both of my ROMs came from the same site, I assumed they would both be the same, either header for both, or no header for either...
I added a header and now it works all good.

SMAS and SMAS+World were patched and are both OK.

Man, you're genius. I waited 13 years for it.
