This is a hack of Super Mario Bros 2, USA. But, the 1992 Japanese version. I chose this version because it has the most bug fixes. Some of the changes:

*Updated palettes to the SNES version
*Restored the albino Mouser in 3-1 in place of the regular one (HP and other attributes have been restored)
*Restored World 7-1 to the original Doki Doki Panic (FDS) version.
*Fixed various bugs at the end credits, such as Clawgrip, Birdo, etc.

I may attempt SRAM saving on this one day. Though, I have never done that before with an NES game.

Patch it to a clean ROM, called: Super Mario USA (Japan).nes

PATCH: SEE BELOW FOR FINAL DOWNLOAD

You sure seem to love fixing bugs. I've cleared mario usa countless times and never noticed any bugs.

Oh yes. I have a real passion for fixing bugs. Which is why I am confident to back my hacks with quality.

The only real bugs in this game are some physics problems such as when you throw a POW over a log you'd go upward and lose a life. Besides that and the credits (which, by the way is stored as OAM) there isn't much more.

Uhm, how about being able to jump in mid air? Although I kinda like that bug I abuse it often when playing the game.

Thank you for that one, Drakon.

I will make a direct link to the Mario Wiki, since it lists them all and I don't know most of them. One day I will fix some more bugs. http://www.mariowiki.com/List_of_glitches_in_Super_Mario_Bros._2

EDIT: Wow...36 glitches?!?

Okay. Here is a new build. It fixes a few issues.

1.
Posted by "TRCF"

The string "ZELDA" is present at ROM address 0x1FFFB. It appears that Nintendo copied the PRG footer/vector table from The Legend of Zelda (another FDS-to-NES conversion) and simply forgot to change the title.


^This has been corrected.

2. I forgot to change to wording on the Game Over screen to say "End" instead of "Retry". This now been corrected. It took me a year to realize I forgot this. "Retry" is really 'Engrish' in this case as you really don't retry anything but instead resets the game.

3. Made it so that the player starts off with five lives, just like in the SNES Allstars version. ($04ED appears to be the lives counter. I traced code and found an LDA #$03 STA $04ED. ROM location is 0x1E425)

4. Made the game to have five continues, instead of two. (Counter for this is found at RAM $05C5)

Original, unhacked version: CRC16 = DE2A
