Is the "+" (plus) character allowed used in files in the Xbox file system?

I can not transfer a file from the Alter Echo DVD (/ODB Data/ODB Media/xvg/Object_Gunshhip_Fly_by_24+.xvg) to my drive, and it seems because of the "+" character. I tried storing other files with "+" in the name, or renaming files to something with "+" and that was denied also. I tried storing with ftp to several ftp servers (XBFileZilla, EvoX, Avalaunch). Avalaunch for example has the "+" character available when pulling up the software keyboard when renaming.

I kind of thought that Alter Echo file was bullshit since "Gunshhip" was spelled wrong, but well, you never know? smile.gif

Do a search before asking a question which no doubt would have already been answered wink.gif

Anyways, have a look here how you can fix it.

Yeah I already fixed the prob with Alter Echo by altering the file references in the appropriate data files. My main question was really about the characters allowed/denied thing. Which was nicely answered by heinlich, thanks!

No - the Xbox file system wont support the chars at all

So far, as far as I'm aware 3 games have had invalid filenames:

1. Enter the matrix - too long (patch available)
2. Alter Echo - + symbol (patch manually using hex editor)
3. Furious karting - french C symbol - no patch out yet

The way they are patched, and the opnly way they can be put on the HDD is by renaming offending files, then changing all links to them using a hex editor. Once done, process can be automated into a patch.

If these are 3 rogue games, then cool, but if this is a new copy protection then hmmmmmn, new app needed.

Not too hard though (although I've never coded Xbox stuff) - I don't think

1. If a file wont copy, rename to a file that doesn't exist (even 000001.xxx or summin)
2. Scan through ALL files and replace all instances with new filename
3. Upload all modied files

If someone can make a DVD-Xbox_HD app that does this it'll be great

Only a matter of time ...

As I said, that's what I did, I searched all files on the DVD for references to that particular file, altered the references with a hex editor to a different filename, renamed file in question. And this should be easy to automate and/or make a patch for games incorporating this kind of trickery. Actually I am surprised it has not been used more often yet, if it seems to be this effective (atleast initially until people learn).

How did U search for references (what software) - I used WinXP seasrch function and it doesn't seem to work

Am I being dumb?

You need to use a hex editting program (like Winhex) in order to see the guts of each file and then you can edit specific bytes. As in the case of Alter Echo, change the + to some other character the Xbox file system can deal with.

Yeah - I can change the content of the files (I use XVI32) - that's cool

But i need to know which files to change

So I need a search program that'll go through all files and look for a particular string - I can then open these files and hex-edit the appropriate characters etc ....

Will Winhex allow me to search 40,000 files for a string as a batch job?

Cheers

Is there any program available that can change the chars and the limitation in batch mode (e.g. 200 files in a directory at the same time) ?

AFAIK, the only way to do it is manually check every file, or do an educated guess.

ie. There wouldn't be any reference to files in audio/movie/graphic etc files.

So no batch search facility at all?

In furious karting I think there is 40,000 files - even an educated guess is gonna be a long job

There must be a search app out there ?!?

I think there is... Norton Utilities has some programs that will search an entire disk for example... and you can hex edit the sector on the spot, without even knowing what file it is...

Use UltraEdit. Hex/Ascii editor and can search multiple files.
