What exactly is wrong with your hack? Does it freeze on the title screen or what? If it freezes on the title screen, restore from the original ROM, the little coin graphic that appears in the status bar at the top.

By the way, basing your hack on a bad dump of the game was probably a bad idea.

As Dan already mentioned -- you should avoid this.

That said -- the good dump and bad dumps should be mostly the same.  Have you tried just applying your .ips to a good dump?  That very well may work just fine.

Unless it's the Sprite 0 problem the others were mentioning.  However since you said it works on most other emus I'm assuming that's not the problem (unless by "most other emus" you meant "NESticle")

A link to said hack (assuming it's released) would be helpful so we can scope it out and see what the problem is.

It's not a spite zero problem it will work with any emulator but fce ultra,
The problem is with fce ultra not my hack when ever I use fce ultra even if I load an unaltered no-title version of smb1
It shows on the screen where it should say 1-1 but not fce ultra instead it shows 0-1 and if you press start it lets you play trough this under water level and if you make it to the end it resets and all you can do is start again and play through the same level over and over again.
This occurs not just because it is a bad dump but because fce ultra assumes it to be automatically because it is incoded that way to Discourage the use of bad dumps what I want to do is find a way to patch my hack to make fce ultra think that it is a good dump even tho It isn't but it will be if I can patch it. Sure I could just patch it over a good dump but that won't fool fce ultra.
I did not base it on a bad dumb either until fce ultra came out I did not know that it was bad.
here's a link so you can try it the bugs in it are part of the hack and I already know about them.

this is the updated less buggy version

The problem is not with FCEUltra.  The problem is with your ROM dump.


This is a bad dump.  Find a good dump of SMB1 and try it.  "(PRG0) [!]" and "(PRG1)" versions should both work.


This paticular dump uses unprepped RAM for the stage number... rather than zeroing it (which the actual SMB cart did).  Some older emus flush RAM with 00's on powerup so it goes unnoticed in them.  However it has semi-recently been discovered that RAM has a greater tendency to be flushed with mostly FF on powerup.  FCEU is probably flushing with FF (which is closer to what you're "supposed" to do) -- Hence why you're getting '-1' instead of stage 1.


I also feel compelled to note that some games do not behave as they do on the console when an emu does NOT flush with $FF.  Most notably is Final Fantasy -- which uses unprepped RAM for the battle encounter marker so the battle encounter list starts at the same point.  A lot of people abuse this fixed state by power cycling the NES so they fight Kyzoku's in the water a bunch of times.  However if RAM is flushed with 00 on powerup the battle encounter list starts at a different point.

So FCEU is doing the right thing in this instance.


EDIT -- I just tried the hack in FCEU with a good dump as well -- and got the same results as akadewboy.  Plays fine until the hammer bro, then locks up.  I'll look into the cause.

EDIT 2 -- looks like a jump table got corrupted?  Perhaps patching to a good dump is not enough to get it working?


$2060 is mirrored PPU registers (not something you want to jump to), so the game ends up hitting a bunch of illegal opcodes until it destroys itself.

Here's an better patch has new clearer read me file and a level select fce ultra save state,
To prove that I played all the way through it in fce ultra.
Also thanks for the help or else I won't have tried patching it over a good dump,
I will get to work on that hammer bros bug.
