Some help making a 1-up mushroom code

[yoshine]

I want to make a 1 up mushroom to replace the super mushroom, (I got this Idea from a texture on the site)
that way you get a life every time you get a mushroom.
To do this I'm trying to modify the poison mushrooms kill you code.
Would it be possible to make a character leave the stage (kill them) and add a life instead of subtracting it?
if so please give me a list of strings or a data base that would help,  tell me what to do in general, or if I'm too stupid figure it out without me cause all I really know now is how to change values around...

here is what we're working with

Poison Mushrooms Kill you:  (Phantom Wings)
4A000000 8077F780 <- value for Item to change I'm guessing
D2000000 00000004 <- Item model?
2C030000 41820010 <- applies to character and or entering stage?
2C1C00F3 40820008 <- unknown
3B8000BD 60000000 <- has something to do lives I'm guessing?
939E0038 00000000 <- unknown

all information I put is just a guess by looking a codes with similar strings on google.
examples are: in game character swap, taunt to kill your self and the item switcher code.

This is a (ridiculous) example of what the original code does:

so basically I need two things, make the code apply to super mushrooms instead of poison ones,
and when you leave the stage you gain a life instead of lose one.
sounds basic enough.
 but I don't really get it....  

Thanks

there is a +1 function in time mode if I remember right.
what if it added one time mode point and brought damage to 0%
if the first Idea was impossible I'd go with that

If anyone around here really knows your stuff now would be the time to speak up!

I can settle for that
