[Help] Cheat to unlock all stars in Super Mario Galaxy

[CosmoCortney]

Good that the Head Size Modifier works
Thanks for testing

Well with RAM dump I mean a copy of the current memory (where we search for cheat codes). It should be a 24mb large file (dont need the additional RAM). IF you don't have a USB Gecko you can dump the RAM using the dolphin emulator. Drag and drop the dolphin.exe into cmd and type "-d" (without quotation marks) behind it and hit enter. Run the game (you may need to press the start button twice) and go to the lobby or any level. on the left side you can get the memory view by enabling it through the menu strip. there should be 2 or 3 RAM dump buttons (depending on the revision). Click the 2 upper buttons. In \User\documents\dolphin\dump\ you should find the files. the 24MB large file is the one I need.
Once we've got the code working I can easily make a code to get any amount of stars
I'm going to make "have all stars of ... galaxy" -codes

[ReyVGM]

Ah ok.

By "lobby" you mean when you enter the little building where the levels are contained right?

Well whatever, here's one RAM dump inside the Fountain building (2 stars collected):

And here's a RAM dump inside the very first level (no star collected in that level):

Thank you!
The look up table is shifted in your RAM dump. that's the reason the code didn't work for you. But I've made a pointer code that works fine for me
Would you mind testing if it works for you as well?

121 stars
48000000 8091E32C
DE000000 80008180
18000218 0000FFFF
1029002C 00000000
e0000000 80008000

Edit: having 121 stars does not unlock luigi. so you have to beat the last boss battle. doesn't matter if it unlocks 121 or 120 stars

[ReyVGM]

Yes!!!!!!! Finally it works!
Thank you thank you!!

Why is it shifted? I mean, did I do something wrong or could the emulator be shifting it?

What number should I edit to have 120 stars then?

[CosmoCortney]

you're welcome
I dont know why it's shifted. could be a problem with the emulator.

this one gives you 120 Stars. The star of the last boss battle won't be collected. But if you have saved your game with 121 stars already, this code won't do any changes
48000000 8091E32C
DE000000 80008180
18000218 0000FFFF
1028002C 00000000
e0000000 80008000

[ReyVGM]

Thanks. No, the save I have only has 2 stars with Luigi. So I could use your 120 stars just fine

I have a question:
If I want to port this cheat to the USA version, what do I need to do? I already looked up a code that is available on both USA and Pal version. The difference between both codes is just 1C.
So what I need to do is subtract 1C from each address in the code you made. Problem is, I don't know which one are the addresses I need to change exactly.

Because, for example, this Mario Galaxy code:

Euro
Quick Spin & Infinite Midair Spin
042B16B0 60000000
C22B14DC 00000002
9BBC01E1 38600000
987C0947 00000000


USA
042B1694 60000000
C22B14C0 00000002
9BBC01E1 38600000
987C0947 00000000


The first two lines have the conversion applied, but the last two lines stay the same. So in the code you made, which are the ones I'm supposed to convert?

[CosmoCortney]

The second block of the first line:
48000000 8091E32C
DE000000 80008180
18000218 0000FFFF
1028002C 00000000
e0000000 80008000

But I don't know if this would be working because the address offsets between 2 versions may vary in different memory areas.
The best would be if we had 2 dumps (one token from the emulator the other one from a wii) to get the code again

[ReyVGM]

Yeah it didn't work. I have the real game, but I don't have any way to dump the ram from that.

All the Mario Galaxy codes ported from the USA version to the Euro version have only a 1C difference per address, if that helps.

Here's the ram dump from the emulated USA version:

[CosmoCortney]

I just had a look at the RAM dump and the address of the look up table is the same as the one from the pal game (the emulated one)
could it be that the 121 stars code without adding 1c to it works for the ntsc-u version, too?
EDIT: It could be working indeed. Went to the initial address, went to the address it stores, took the offset of 0x0218 and landed at the look up table!

[ReyVGM]

Oh, I never figured to try the same code! And whaddaya know, it worked!! This is great! However, I had to enable it while in the observatory (the Hub). If I load the game with the cheat on, the save file won't start.

You are awesome Courtney, thanks for the amazing code, you've saved me from having to play the game a second time and now I can finally put SMG to rest!

Thankfully SMG2 already has codes to have all Stars. I haven't tried them, but hopefully they will also work.

[CosmoCortney]

welcomes, and thanks for testing!
I didn't noticed the code freezes the game on the profile select. But that should be easy to fix (except for the NTSC-U version, because I don't have the game but i could try adding the offset of 0x1C to the additional address)

[ReyVGM]

I'll test it if you want.

Or you can just put a note to only enable while in the observatory or something like that.

Thanks^^
Wenn, for all of those who use it on the wii would need a button activator to enable it.
that would be a solution too.
but i'd like to use an address which has a specific value when you can actually play mario/luigi (like in the hub, any level or lobby) to prevent freezes by exploiting it for an if-equal condition. I have done this very often since this is a very common problem with pointer codes

Can you verify this code to be working on the wii and dolphin emulator for the PAL and NTSC-U versions?
206BCA4C E0000000
48000000 8091E32C
DE000000 80008180
18000218 0000FFFF
1029002C 00000000
E0000000 80008000

it should unlock 121 stars and prevent the freeze

[ReyVGM]

Yep, worked perfectly both pal and usa version. No freezes and I had the code enabled as I turned on the game.

Unfortunately I can't test it on a real Wii because I don't have a cheat device for it.

Your wii does not have homebrew channel install yet?

when homebrew channel is installed you can run emulators and Gecko (cheat device).
