Will MODE on Dreamcast require hacking your power supply?

With Dreamcast ODEs, there's a problem with power supplies getting hot which has to be solved by replacing the power supply or disabling the 12v on the power supply. Will this be necessary for the MODE?

No. MODE is designed to work properly with both original PSUs and 3rd party ones.

You might have misunderstood the question. Removing the Dreamcast GD-ROM drive removes the 12V load on the power supply. The PSU continues to supply that voltage, and since it has nothing to use it, the result is potential overheating and gives off maybe an ozone smell. Does MODE draw that 12V load somewhere?

MODE provides a dummy load on the 12v rail thereby keeping the original PSU properly regulated unlike GDEmu and others. MODE doesn't require the 12v at all, so if you use a 3rd party solution that doesn't have a 12v rail it will still work correctly.

So, no, I understood the question. 8-)

Well that answer is what I was looking for. :D I was thinking I'd have to install a Noctua Fan or something like that to take the load. I wasn't interested in removing the 12V regulator from the PSU because I use the modem for Dreampi gaming.

The Noctua fan is still a good idea since the DC in general does get very warm and the noctua is significantly quieter than the stock fan.
