From what I read the other 20% overclock should also work with dchdmi as that runs off the GPU and not the CPU.
But the simplicity of the 10% without the aggro of VMU corruption makes it one of the bes mods avaliable, IMO


Thank you for the upload. You have some really great videos on you channel! Having to have two sets of VMUs was a deal breaker for me, thats why I sold my 240Mhz Dreamcast. 10% looks much better. Only time will tell if the 10% overclock is a mod that can in essence just be done and then forgotten about.

Have you notice any issues at all? Is this your daily use Dreamcast?

Has anyone actaully confirmed the clock signal with a scope? I am unable to find a datasheet to check that the IC chip actually has an output for 36.67Mhz

I guess the mod is good, it just deserves a comparaison between standard and 10% overclock.
With a game like shenmue 2 for example, run around the pigeon park fontain is a good place.

I still have my cristal to overclock at 20%, but i don't do the mod, I'm afraid to break something ^^

I would imagine potential issues with this mod when using a GD-EMU.

I don't have any issues with 240hz on gdemu that I didn't have with disc. Mode does not work with 240hz though
