N64 MarioKart Rom Edition - HELP !!!

[Flomox]

Hello People,

I just found this awesome forum and suddenly start to feel hope again.

Can someone help me ?

I want to edit Mario Kart 64 in some ways.

The most important thing is that i want to rebalance the PowerUps.
I would like to Deactivate Stars in "battle" mode for once - thats most important.

Then i would like to have an "green turtles only" mod

Then i would like to implement new maps.

Very nice would be if its possible to implement an NetCode so its possible to play MarioKart online with friends :P

I just was able to open the Rom with an Assembler tool.

All those strange hex code ... i have no clue which variable stands for what.

how can i find that out ?

You'll have to learn the MIPS Assembly Language (http://en.wikipedia.org/wiki/MIPS_architecture#MIPS_Assembly_Language).

Alternatively, you can just start breaking things in the hex editor and try to figure things out via trial and error, but if there's any compression involved (and with N64, it's quite likely that there is) then you won't make much progress.

Thanks for the Answer.

I would learn the language if it helps.

Cant you just tell me how i find out which values mean

"powerup" and "star" ?? then i knew where to work on

you could use renegade to search memory changes for modifier cheat codes...which will lead to understanding the items table and their values for different items like the star

possible you could disable via cheats

There may not be a single value that means what you're looking for. It may be several values, or it may be something that can't be changed by simply modifying a few hex values. Every single game is different, so unless someone has already hacked the ROM you're wanting information about, nobody is going to be able to tell you where a particular byte is located or how to find it.

what is gameshak ?

Someone said there is a page online where you find the codes for roms..

or more like the IDs of special items in the code ... i cant find it. anyone knows ?

I am total noob. what means "use renegade" ?

Well, a Gameshark is a cheat device (but it's codes are also supported by some N64 emulators). It changes things in RAM to cause varoius effects (for example, in many games you can easily find a code for unlimited lives, invincibility, more ammo...etc).

Here is a side with various gameshark codes

Not without doing an extensive amount of work. The only way anyone is going to give you the information you're looking for is if they happen to have already been hacking the game and came upon the location of the data you're interested in. Nobody is going to spend what could potentially require a lot of time to find one bit of information for you when it does nothing to benefit themselves. Now, if you want to come cut wood for me while I'm searching for it, we might be able to work out a deal. ;)
