How to apply rgb patches to dreamcast games?

[Tackskull]

Hi there,

I have a japanese dreamcast with a brand new terraonion mode installed.

But today I discovered that few games don't support RGB video.

I found on this forum a list of patches to make those games run on rgb.

The fact is that I don't know what program to use. I tried "pp o matic" but seems to work only with ps1 games. In fact, as the autor of the post said, I patche the track19 of the US version of Centipede. And didn't worked with ppf o matic.

There is another ap to use?

Five posts.

Alternatively, you can apply the patches yourself: https://consolemods.org/wiki/Dreamcast: ... GB_Patches

EDIT: Oh, and I also shared them here, I forgot: viewtopic.php?p=190119#p190119

Thanks for that info. Shame it doesn't include some of the others I've run into on my fresh GDEMU install, particularly NBA on NBC Showtime (my stepkids love NBA Jam so I'm hoping to figure that one out at some point).

Unfortunately when it comes to RGB, you're going to run into this. Strongly advise seeking another video output method.

Actually, I took a quick look and cannot replicate broken RGB with NBA Showtime using an emulator in either North American or European console mode. I'm looking at the disassembled code where it does all of the video initialization logic, and don't see how RGB would ever fail.

Which console region are you using, and what issue specifically do you see with RGB?

US NTSC via VGA cable, and on GDMenu I see this:



Which leads me to the typical "game won't load with your cable, please restart" prompt. Do I just need a different rip of the game? Or what else am I missing here?
