hmmm.....perhaps some type of circuit to hit a switch every once in a while....could be done relatively easily, I think...anyone want to try? I could maybe figure it out, but that would mean relearning a lot of stuff about clock circuits and whatnot, and quite frankly, I don't have time right now !!!
Without games my life would have no meaning.
Well, I guess it would, but it would be a lot less fun!!!!!!!

That's a POC! (piece of cake)
Just get a PIC16F627 or PIC16F84 (whichever you happen to have) and write some simple ASM code to drive a transistor every 30-40minutes.
Or what would be better?
Use a resistor-capacitor network as an DAC to remove the green tint.
In fact, you could probably just use a simple 1-transistor amplifier for each RB line. The overall screen would be slightly brighter, without a green tint.
I hope you can make some sense of my rambling. Why not just amplify the red and blue signals to cancel out the green?

Ben is probably talking about one of the new Intersil sync chips, the ISL59885 or EL1883. Neither of these work as a scan doubler and as far as I know there's no such one-chip solution for scan doubling. It takes a crap load of work to make a sync scan doubler looking at the scehematic on ELM's page (elm-chan.org) and it's probably something I will never attempt. You gotta stick with an X-RGB for that ;)

I don't suppose it would work, but... Has anyone tried the touching-the-lines-with-switches trick to see if it gets around the RGB DVD playback problem (anti-piracy)? I suppose you wouldn't know, segasonicfan, because you already had a modchip installed when you did this fix, right?
If not, does anyone know of a way of getting around that without using a modchip on a Slim PS2? If you're worried about derailing the thread, PM me the answer to this particular question.

heh, this thread is so old...lets go ahead and derail it :P
I'm 99.9% sure the switch trick will not fix the DVD playback. That's macrovision protections which is Sony encoding the crap out of the RGB output through the PS2 chroma encoder. There is no way to fix this without modding the PS2 in some way, since it is encoded from the source and quite hard/impossible to decode to get pure RGB again.
There's a mod out there for old PS2's where you can cut a trace to disable RGB but there has yet to be such a mod discovered for the slimline (as far as I know).

Ah, I see. Oh well. I did some reading last night. Well, a lot of reading, googling, etc. Looking at modchips, boot discs, comparing prices. Appearently the DVD Region X disc can get around the DVD-RGB problem. Some one sells them fairly cheap on ebay. But.. I can get a decent mod chip for not much more. Might end up getting the Ghost 2. It's fairly cheap and should do what I need.
