I have made a patch that will allow anyone to use my 100 Coins/Star ability in their hacks, or just add a little spice to the original game if they want. The file contains the patch, and a small readme. To download, right click on the link, and select Save Target As... http://www.geocities.com/heavencloud7777/star.zip |

If you get 100 gold coins you should get a hooker. A really nice one too, I mean c'mon it's GOLD. | |||

OMG WHERD U GET TEH STAR I imagine it only changes a few bytes? Probably not much harder to do in SMB. I might look into it. |

I'll tell you how I did it. First, I needed the code for the star. So, using FCEud, I wrote to the address, $553, which is the Invincibility Timer. When I touched a star, the debugger snapped, because the address was written to. Scroll up a bit to see the code. $A808:AD F5 04 LDA $04F5 = #$0A $A80B:09 0A ORA #$0A $A80D:8D F5 04 STA $04F5 = #$0A $A810:A9 E0 LDA #$E0 $A812:8D 53 05 STA $0553 = #$00 ------------------------------------------------------ $A808:AD F5 04 LDA $04F5 = #$0A $A80B:09 0A ORA #$0A $A80D:8D F5 04 STA $04F5 = #$0A This controls the music for the star. $A810:A9 E0 LDA #$E0 $A812:8D 53 05 STA $0553 = #$00 This activates the star. Then you have to write to $736, which is Player 1's lives counter. (this can be done for player 2 also, but I didn't feel like doing it for Player 2. Looks like Luigi gets fucked over again. ) When you get 100 coins, the debugger will snap. Highlight that code, and find it in the hex editor. FE 36 07 is the code that gives you another life. Jump to free space to put the Star code in, since it won't fit in the space thats there. That means, overwrite the FE 36 07 with 20 20 B5. 20 is JSR. 20 B5 is reverse for $B520, which is where I found at one time there is a lot of free space in the ROM. Then NOP the rest of the code out with EA(s). Just the music code for the 1-up. At $B520, which is 0x35530, I put the code for the star. Just put in all the hex values for the star code. Then return using RTS. Which is hex 60. Presto! Any questions? |
