    This is me too. I'm not interested in using a CRT as I'm just not a fan of how they look. I've had the Super Nt for about a month now, and with my Mega Sg arriving yesterday, I have completely...

    I pre-ordered one and it turned up yesterday. It really is amazing, though there are a few minor niggles. Firstly, I like how you can scale the 256 and 320 pixel wide modes independently, but the...

    Apparently version 1.032 has some issues. I tried version 1.031 and it works fine. Also, my DC is a VA1 like the vast majority of them.

    If I had to guess, it's some degree of coil whine. You can always try replacing the inductor to see if that helps.
  5. Dreamcast Japanese Cake BIOS won't read backups

    Hey all

    So I've recently installed a replacement BIOS into my Dreamcast, and it had the Japanese Cake 1.032 version on it. I've used it before on another Dreamcast, and it worked flawlessly, but...

    I used to remove them as they don't really serve any purpose, but nowadays I leave them in. It's more of a placebo thing for me, they add weight to the console and make them seem more premium.

    Thereís no difference in hardware at all between an NTSC and PAL region Mega Drive, the only difference between them is the jumper settings to force the region mode, and the master oscillator. You...

    You will if you use composite, because the colourburst frequency will be wrong. This isnít a problem with RGB because the colour isnít encoded to begin with.

    Changing the crystal wonít introduce jailbars, but it might change the RGB signal, depending on what you are feeding the signal into. For example, the Framemeister interprets the 60Hz signal from a...

    I have an NMOS Z80, but itís a cerdip. So, better heat dissipation on that anyway.

    Have you recapped your entire system? Old caps can be a cause of bad audio. Itís always the first thing I do when I get a new system, even if the caps are still fine, it just prevents problems later...

    So my caps turned up, and the jailbars are so faint now you can't even see them unless you put your face right up next to the monitor. I actually removed the surface mount caps whilst I was at it,...

    I opted for ceramic 10uf caps, so polarity doesn't matter xD. Going to give it a go tomorrow, I attached the 0.1uf on the underside of the board through the two vias that are present there, so I'll...

    I think itís just because the headphone socket on the model 1 is somewhat janky, particularly due to its age. Thereís something about 3.5mm jack sockets that just get worse over time.

    Iíve had this problem too, and my issue was the sync line was shorting to ground somewhere in the cable. I ended up sending it back to the place I bought it from and they repaired it under warranty.

    Thatís correct, a modded PAL machine does not run at the proper 59.91Hz. The only way to correct this is to replace the oscillator with a proper NTSC 53.6931MHz one, but that will leave your PAL...

    Sega CD is super underrated. It had such a lot of potential. I wonder if there are any homebrew developers working on new software for it.
