How to hex-edit subtitle colors in .ifo file?

[schmeg]

Greetings, all --

Does anyone know how to change the colors of subtitles by editing the .ifo file using a hex editor?

I'm working on a Mac, and therefore don't have access to IFOedit and other useful tools. We have a few good programs for ripping DVDs, but even those tools that allow an imported VTS*.ifo for the color palette give haphazard results. (I just burned a disk with pink subtitles, which is much better than the more common black with a dark-blue outline...)

Can some clever person can figure out which hex addresses in the title's .ifo file control the color of the subtitles? Who will be my hero?

Unfortunately, almost everything in IFOs is indexed by pointers, so there's no direct address. Take a look at MPUCoder's page if you want to make a little binary patcher by youself - but it'd be a hell to do it with just hexeditor :(

Have you ever heard of "Virtual PC" on Mac?
If you Mac has only 400MHz and 64MB RAM, then - buy a 300$ PC with AMD DURON 950MHz and 128M SDRAM, 40GB HDD etc...

Thanks, Yusaku, for noting how .ifo's work. I should have expected that it wouldn't be easy...

But if you instlled "Virtual PC", you can run IfoEdit to get the "disassembled" control code of the DVD, and edit it...
