Dreamcast textures?

[gracik]

Can anyone tell me how to change textures in a dreamcast game? Because I've been looking everywhere and I'm not getting any answers. I seen one site talk about the TEXMOD method, but they never explain the whole converting the texture step. So any help would be nice.

PVR format ? There is a pluging for photoshop and extractors/packers to bmp .

It depends on what you want to do.

If you want to make a disc and play it in your real Dreamcast, you have to change the pvr files using the methods Vasiliy mentioned above. Of course it all depends on the game you want to mod, sometimes pvrs are stored inside archives or use a special unrecognizable header, are compressed using a custom compression, etc...
Oh, but make sure to convert them to png, else you'll use the "alpha channel" (bmp doesn't support those)

But if you wanna play it with NullDC, just emulating it on your PC, I used to have a program which runs together with NullDC and captures/replaces Textures. Maybe I still have it lying around, back in the day, I used it to do something related to pvr compression. If only I could remember the name.

Anyone else remember it?

Well I just want to play it using NullDC. I have three games at the moment, SA 1, SA 2, and Royal Rumble. And I just wanna make a test run changing textures on one of them. So I can get use to it.
