If you're using an HDMI converter then that's most likely your reason for Hydro Thunder not working. Hydro Thunder notoriously doesn't work well with VGA output (HDMI converters for the Dreamcast usually convert the VGA signal)

I figured out how to fix Hydro Thunder's compatibility issues last year (it would very briefly change the pixel clock). You can either use a Codebreaker code to fix the game if you're running from a real disc, or if you use an ODE, you can patch the disc image.

This reminds me, I remember back in early 2000s hex editing games to force 60hz on my PAL Dreamcast. This looks like a similar idea. Thanks.

To be honest I now pretty much just play Dreamcast games via the redream emulator on my steam deck and pc under my TV. Though obviously there are drawbacks with emulating. Every so often I bother to setup my Dreamcast with my ossc and play on real hardware.

VGA to my ossc is usually how I connect to my TV. But yes I believe you are right, it's a vga issue too
