works on BizHawk latest version

Glitch Minus World Tile with Load Game in SMB1 File Menu,
In World 1-2, Warp to World -1 (like World 2-2), Save & Continue.

Removed Minus World (changed warp -1 to 2-2), fixed like SNES version of SMB1 or SMBD for GBC.

Hard Mode in SMB1 with SRAM,
World 8-4?? beat the game and save, changed to World 1-1 like all replace Goomba with Buzzy Beetle.

Added Star Tile to World (for example W1-1*) in File Menu with Hard Mode Only, all replace Goomba with Buzzy Beetle (SMB1 Only not SMB2J).

can't change world (Left/Right button for world and press A button for stage), beat the level in File Menu like SNES SMAS or SMBD for GBC.

can't Pause Menu with Save (press Start button) with Map Screen in SMB3 like SNES SMAS or Southbird's SMB3Mix.

Plans for new version of SMAS NES?
-Removed Minus World in SMB1 Only.
-Hard Mode support (SMB1 Only) and Star Tile to World (beat the game) in File Menu (all 4 games).
-Change World (for example W1-1 to W2-1 or W8-4 to W1-1*) (beat the level) (all 4 games).
-Pause Menu with Map Screen support (SMB3 Only).

I never even thought of the minus world. i don't know how to activate it, I thought this was just an emulator based glitch to the rom?

Thanks for the info Insectduel! :-)

Well i've decided to keep the glitch intact. I was able to achieve getting to -1, and saved from there. It turns out, that 23 gets loaded into $75F ram (World ID). So when it comes time for a user, to reload his/her save file from World -1, I do a hard coded check for 23 within the specific sram register for that save file. If it's 23, I then perform tile writes, to make the World number look blank.

Again, this is only for when the register fills in with 23. So idk if any other value gets stored within there. All I've had seen, is World 2-1 loop over and over once you enter the pipe at the end. So I believe I have resolved the tile glitch, and i'll upload a video of my proof.

What I also found cool, is when you return to the title screen once you've gotten a game over, you can obviously start back to World 1-1. BUT, when you get a game over from the Minus World, and you are at the title screen, if you hold A & press and hold Start, you will start back at the Minus World, just like if you got a game over in say, 3-2, and held A and pressed start to start back at 3-1. :-)



OK another update.

So again with Super Mario Bros, that game is all set with the Minus World, and no more issues are present.

I went to check out Super Mario Bros. 2 Japan, to make sure the same loop issue with 8-4 didn't take place, and it doesn't from what I've seen.

I was asked if I could add the STAR icon to file menus, when you have defeated whichever game you are playing. I'm deciding to go down that road. Super Mario Bros. & Super Mario Bros. 2 Japan, will be a piece of cake, since those 2 roms have dedicated registers for when you do defeat the game.

Super Mario Bros. 2 USA & Super Mario Bros. 3, this is going to be an issue. I don't know if those two games have dedicated registers for when you defeat the game. I know that when you beat Mario 3, you get a full inventory of P wings. I don't know what triggers that, but if I know the routine that fills your inventory with P-wings, I can slip in a sub routine to set a register within that games sram file, to signify that file has a defeated game.

I'm not sure i'll add a save menu to the world map of Mario 3. I know the original All-Stars does it, but I have everything based off of when you are in a level, and some of those registers are used differently when you are on the world map. I know this may be a slight inconvenience for players who want to save in a pinch, but I really have no desire to go further with the sram than it already is.

So, if anyone knows about the P-wing full inventory in Mario 3, and what my best bet should be with Mario 2 USA on when to signify you defeated the game, that would all help greatly. :-)

Once I get those all ironed out, i'll release what should be the absolute final version. Thanks again everyone! :-D

In the international versions of the game, pressing a button after the ending sequence will return you to the title screen, whereupon starting a new game will give you a full inventory of P-Wings (and Hammer Suits if the game's beaten again afterwards). In the original Japanese release, this feature was not included, and the game will remain on the final screen until the Famicom is turned off.
