Yeah. I need to rename it, I suppose. It also lets you jump in water. I hijacked the water physics routine so Mario doesn't swim, but moves slowly and jumps higher. With the (Space Jump) you can roam freely in water as if it were air, just like in Metroid.
The door is actually a pretty simple sprite. One shot (or five, for red doors) sets a timer to decrease, which changes the GFX along with it, and when it reaches 1, it zeros the status so it disappears. I was going to use the Fireball Hit routine, but there is a bug with it that when you shoot something once, it increases the hit counter ($1528,x) each frame. So instead, I set $1528,x to #$FF in the init routine then I decreased it again in my hit routine, so the sprite wouldn't die when hit with a fireball. At the same time, it INCs $C2,x, which is the HP for opening the door. This is a roundabout way of having fire HP. Kind of inefficient on paper, but it works fine in game. The bombs are set to INC $1528,y for this sprite and another which I use for secret explodable passages. -------------------- I've removed my NoFades patch until I can find the brightness code for Star Road warps. |

Everything important is commented on in the ASM file to the left of the code. If you want to change something, just read the comments and find what you want to change and change it.

Possibly. I tried setting the fire HP to something below #$FF (like #$F0) to see if it would count up from there, but after one hit, it rolls over to #$FF automatically. So, if you have five fireballs to kill checked, it would take 6 fireballs by setting the fire HP ($1528,x) to #$FF in the init, unless you do what I did with the door and use another sprite table RAM for HP instead.
Here are some snippets of code from the door sprite (I added comments so you know what's going on). Try it out in some other sprites and see if it works. Fire kill must be enabled, as well as 5 fireballs to kill. In the init routine, we use this. Code dcb "init" LDA #$FF ;set fire hit count to #$FF STA $1528,x RTL Somewhere in between, we have the code to tell it how many hitpoints before the code jumps to kill, or whatever you want to make it do. I'm using $C2,x, but you can use any of the sprite tables that count only one frame at a time, like $1534,x. Code LDA $C2,x ;if HP scratch RAM CMP #$05 ;is five BEQ startkill ;jump to the kill routine This is the actual fire hit code. Make sure this comes after the HP check to kill code. Code LDA $1528,x ;if fire hit
CMP #$00 ;is zero.
BEQ DOINC ;then go to increase code
LDA $1528,x ;if it's #$FF
CMP #$FF ;Don't increase other RAM
BEQ NOINC
DOINC ;INC codes
INC $C2,x ;Increase C2,x (We're using this for HP
LDA #$FF ;and reset fire hit RAM to #$FF so we can use
STA $1528,x ;it again on next hit.
NOINC ;continue with code...
...
RTS
After that, put your kill routine in, or you can even make it do something else if you want to. -------------------- I've removed my NoFades patch until I can find the brightness code for Star Road warps. |

Yipee!

The blocked status uses bits. Try this.
Code LDA $77 ;If blocked status AND #$01 ;is right BNE DORIGHT LDA $77 ;If blocked status AND #$02 ;is left BNE DOLEFT RTL -------------------- I've removed my NoFades patch until I can find the brightness code for Star Road warps. |

You might try using Mario's speed, then.

Yeah. If he's jumping straight up, it might pose an issue. You could also use controller bits in that instance. If in the air and pressing right, do right, if in the air and pressing left, do left. I'm just throwing options out there.

Wall Jump depending on powerup status.
Wall Jump for Luigi only. (Or could be set to Mario, but since Luigi is the one who jumps high...) Wall Jump after (Yellow,Green,Blue or Red) Switch is activated. They could use the specified color in map16 for a nice touch. -------------------- I've removed my NoFades patch until I can find the brightness code for Star Road warps. |

Nicely done! I like the Y register trick.

5C8E - #$18 is the current pose for in air fireball shooting, which is swimming frame 3. This is what you would change. Use the Mario Poses file from the document section to pick a new one.

Ah! I see. I read the log wrong. Be right back.
[edit] Ok. Try 517B. It's currently 16, which is swimming pose 1. -------------------- I've removed my NoFades patch until I can find the brightness code for Star Road warps. |

I hijack the hurt routine in the patch, so you'd have to create a table and routine in another patch and JSL to it in the hurt code that's in the health patch. It would take a lot of work that I don't feel like getting drowned in at the moment, but it would be possible.

Here is a version of the Chomp Shark that eats only Turnblocks and Throwblocks. It also shatters them.

Actually, you can change it with a simple xkas patch. Use This Status Bar Tilemap to select tiles where the STA lines are.
Code lorom header org $8E6F ; Time LDA $0F31 ; single digits STA $0F0C ; store single digits on this tile LDA $0F32 ; tens STA $0F0D ; store tens on this tile LDA $0F33 ; hundreds STA $0F0E ; show hundreds on this tile Or you could just move it with the status bar tilemap editor. It's way easier. -------------------- I've removed my NoFades patch until I can find the brightness code for Star Road warps. |

I played it last night. It's quite nice. The controls are a little touchy, but other than that, it's well done. I like the Mew teleport effect when running fast.

I would like to see this applied to the Mario graphics page. It would be cool to have different player graphics in a level if so desired. I saw it done in a Japanese hack, but I have no idea how they did it.

Tip: Always double-check which slots the ExGFX you are trying to insert goes to, to make sure you don't get accidental glitched graphics elsewhere.
