Are you using a tv or a vga monitor?
I did this circuit once and it worked as it should on a pc monitor. If I remember well, in vga mode the signal is progressive.
I think the only time I had black and white was when I connected ntsc composite video on a pal tv (it's been almost 10 years)

Re: Very odd PC problem...
Look for leaked capacitors on the motherboard
see there for informations :

If you've got some bad capacitors, you'll need to have them replaced or to change the motherboard.

2 months ago I had no problem compiling the toolchain with ubuntu, are you using the svn version of KOS ?

Re: Bad Firmware Flash Woes on External HDD
you probably can't do anything more, you'd need to reprogram the flash using a flash programmer since the self programming part must be damaged now. Maybe there's some jtag workaround but only the manufacturer must know of it and you'd need specific hardware to do this. And I assume you can't open t...

Re: Battery Replacement
It's soldered on the board and it's a 3,6V rechargeable battery. Ask a technician to do it for you.

Re: Did the modem LED mod again, issue though..
double check if you didn't short two pins together when you soldered your wires, your modem may be dead now.

Re: Please help! Dream Cast controller port!
do you mean : if you use only one controller it works ok, but if you plug too many it doesn't work and if you keep only one plugged it works again ?
If so, you must have a 10 ohms resistor on the controller board, which is wrong.

Re: Simplygon
well of course it can be useful if your game engine lags because the models you use have too much polygons.

Re: Verifying Power Board Replacement/Rumble pack feel decreaser
if you don't find a near zero fusing resistor, but use a 10 ohms one like lot of tutorials say to do, you'll probably don't feel any rumble anymore. I'll repeat one more time : the original resistor is a fusing resistor. It's value is about 0,4 ohms. I you use a 10 ohms resistor, it should work for ...

no you can't without a dc-dc converter, the dreamcast will work at 4,8V because it's close enough of 5V but it won't work for 3,7V. And you better use a single battery and a converter that gives you the 3 needed voltages. it seems they feed 5V where 3,3V is needed, whil this may work, it's prone to ...

no, adapters quite NEVER work in reverse, because they'd be much more trouble to build (and humans are lazy). Just think for example of a power supply unit, it won't give you 110VAC if you powers the dc part. Same thing for a vga box, it's one way only it converts the dreamcast output to vga, but ca...

an ohmmeter is used to measure resistance, you find it at radioshack or any electronic shop. (it usually includes a voltmeter and an ampmeter in the same tool). The cheapest are probably worth 15 to 20 usd buy a new controller, if it doesn't work either, it's probably f1 that's burned (it's on the c...

Well if you plug/unplug controllers while the dreamcast is on, it theorically creates an infinite current spike, in the real world the current spike is finite. I think that everybody already unplugged/plugged back some controllers some day without busting anything, but it COULD damage something. If ...
