Custom Isos

Another idea which may have little or no affect: in the hex editor change every instance of the game ID to something which isn't the ID of any existing game, but that looks like an ID. This may help to confuse dolphin enough to think that it isn't the same game.

LPFaint99 already said that the title_id needs to be changed :/

[AnyOldName3]

Actually, he didn't, he just asked if they were the same. He didn't suggest that it may be possible to change it, and he didn't specify how one could go about changing it. You are an admin, so shouldn't just skim read.

I guess I assumed that it went without saying.

Title ids are the same, save path is determined by title id, and dolphin uses banner from save path to determine game name.
for the games to show different names they must have different banner files, so they need different save paths, so they need different title ids.

The "title id" change from the first post was apparently done wrong.

EDIT:
First I should clarify there the game id, and the title id.
for the example of mario kart RCME is the game id. RCME01 is the game id + maker id
the title id which includes the game id for example mario kart is 0x00010000-0x52334D50 0x52 = R 0x33 = C, etc

The game id is stored at the start of the iso, followed by the maker id
I assume usb loaders use the start of the iso for this (check the iso in a hex editor, bytes 0-5)

the title id is stored in a few places, notably in the ticket, and the tmd

I assume the title id was not changed in the tmd.

It is certain that it was not changed in the ticket because that is what dolphin uses to find savepath.

So, now you have graced us with the knowledge that we have been needing (which bit of the iso dolphin uses to find the ID), can you tell us how to change it?

[LPFaint99]

I'll point you to the tools, but I won't give you a step by step.

see dolphin's source or wiibrew for the layout of wii discs.

have a backup before modifying anything that you might not be able to recover. find a hex editor that you are comfortable with or maybe there is a tool that will do this for you.

[AnyOldName3]

It isn't me who needs the step by step, as I have no modded isos, unlike the op. also it would be much more helpful to post links to the correct part of wiibrew if you are bothering to post any links instead of making me google it anyway.

If I have an exasperated and angry tone of voice/typing then it isn't really aimed at you, just some idiot in another thread.

[LPFaint99]

a link to wii disc is on the front page of wiibrew....

[AnyOldName3]

Oh, OK then, but I didn't see it first time around. Anyhow, where is the op? I'm sure he'll be glad that we've finally made some progress.

He is where ever he is when he's not here posting?

I understand you're the next new guy who is here to show everyone how much he thinks he knows about everything (we get those guys all the time here), but after reading some of your posts, I'd like to officially remind you to check your attitude before things get out of hand.
