This is a hack that includes both SMB1 and SMB2J. Almost every single known SMB glitch has been fixed.

There are two sides to this ROM (the sides can be switched by clicking the button at the bottom of the game window [Eject/Switch/Insert] at "Nintendo Loading" screen).

Side A:

This is a hack of SMB2J that brings all the level designs and other various data over from SMB1. I hear all this hype from many other forums of people wanting to add SMB2J stuff to SMB1, such as Wind, Upside-Down Piranha Plants, more Worlds, etc. So I did something about it. I thought to myself: If the point of the hack is to make SMB1 like SMB2J, why not just hack SMB2J?

So that's what this is. SMB1 with all the features of SMB2J. The levels are the same, I've just incorporated SMB2J stuff in various places to add and show off its features. I've done all the work on this myself so that people can now rip their SMB1 levels and paste them to this without having to worry about the ASM work (assuming they don't know it).

There are no Worlds A-D in Side A of this hack as I NOP'd the code that does a check to see how many stars are on the title screen. World 9 is still intact. What I did was recreate the Minus World from both SMB versions (NES and FDS) to make a World! The NES Minus World has 1 level, while the FDS version has 3. So 3+1=4 or 1 World. This is better because the SMB2J 9 World is based off of this Fantasy glitch from the original game. So doing this is only fitting. Well, minus the glitches that came with the original Minus World. I even gave the NES version a total makeover of its Minus World!

• 9-1 = NES version of Minus World
• 9-2 = FDS version of -2
• 9-3 = FDS version of -3
• 9-4 = FDS version of -1

Side A Key Features:

• Poison Mushrooms, green springs etc. can all be found in this game.
• Beta scenery and cactus have been used from SMB2J
• Saving occurs upon beating 8-4; high score is also saved to SRAM upon receiving a Game Over and choosing "Quit"
• Wind and flying Bloopers have been added to some stages.
• Upside-down Piranhas have been added to various areas in appropriate places to give it an authentic "Nintendo" feel.
• New invisible items have been added where there were only invisible coin blocks.
• Remember, SMB2J is on Side B of this game!

Side B:

• SRAM saving (completely redone; upon getting a Game Over on any world except 9 World; and when beating 8-4/D-4. Only saves the highest score.)
• I've added features from the SNES Allstars version:
º Hard Mode on Worlds A-D (where Buzzy Beetles replace Goombas and all enemies move faster, smaller platforms and anything else found in Hard Mode)
º Bowsers now have their own identities when defeated in Fiery state (originally they shared Bowsers World 1-4 identities since Worlds A-D were counted as 1-4 before. I even fixed the A-1 identity glitch found in the Allstars version.)
º Worlds A-D now have their own attributes and no longer share codes and limitations the original, such as spring in World B being red like they're supposed to be etc.
º I've written a little routine in bank $02 to play the beta Game Over music when loading the special message for 9 World

• Many sprite loading issues with OAM have been corrected
• I've fixed every single SMB2J glitch known to man...including:
º The timer would erroneously award player 999 seconds if the timer got down to 0 (50*999 =50, 000 points)
º The platforms had a collision error where they would loop instead of kill the player if they went below the screen ($D0)
º The hammer immunity glitch has been corrected where if the player went all the way to the left of the screen, the player was previously immune to hammers
º The glitch on 4-2 has been corrected
º Lakitu was originally supposed to throw Spinys according to the player's velocity. I fixed this. (A was getting overwritten because the JMP to bounding box control was too early.) Now Spinys bounce and Lakitu moves better. The only other version that fixed this was SMB Deluxe on GBC.
º Infinite lives glitch where the player would receive a Game Over upon accumulating too many lives.(I credit this fix to Kasumi, who gave me a hand with this)
º Many other glitches I corrected based on videos and the Mario wiki

• New features have been added, including:
º A brand new sunset palette has been added. It always bothered me that we had day and night stages but none in the evening.
º Brand new snowy palette. It always bothered me that the shrubs were colored white but the ground was left brown. (I had to clear 8 bytes in the first VRAM table data to make room for this.)
º Brand new bonus areas added and a hidden new level! (World 9-4 = new bonus room, World A-1 = secret hidden level within the stage... 2 exits in total! [Can you find the hidden level? ], B-1 = new bonus room with beta enemies used [can you find the hidden message? ], C-1= a very special new bonus room, D-2 = ??? [I think this stage speaks for itself]. No rooms were taken out; only stuff added
º Underwater currents [9-4 only] - These use the same wind code as on land except I had to code them to push the player around, as wind would previously only do this on land stages.
º Level fixes from the Allstars version. Some of them include the fact that on the NES version it is impossible to get 5000 points as either form of Mario on some stages like 2-3 and 8-2.
º I've also found a TON of beta stuff. Like unused blocks, BG scenery, etc.
