Is the titler the only source of NES PPUs that output RGB and share the same palette? I know if you used the VS Unisystem PPU you may have palette color issues in NES games.
Most people who do RGB mods get their PPUs from Playchoice-10 cabinets, which I think is pretty wasteful. The Famicom Titler is great: it's got RGB (with a simple modification), S-Video, Composite, and can even convert an S-Video input to composite so I can hook up my computer to my TV.
The RP2C03 used in the Playchoice 10 arcade board (and VS Tennis and Duck Hunt) and the RP2C05 used in the Sharp Famicom Titler are the only PPUs that can be used to generate RGB however there are many minor differences so that some colours will look odd or show the wrong shade so some games may be unplayable, although those games are few and far between. It's a easy enough mod to do, just requires an amp circuit and desoldering of the old PPU chip.
Wait, the Titler has palette differences or no? I would think the Titler is ideal because it's palette should match perfectly, as it is the home console.
This is a modified New Famicom which uses RGB: http://page5.auctions.yahoo.co.jp/jp/auction/e69329198 It sold on Yahoo a few weeks ago, got almost $350. Looks like the Sharp Twin Famicom has a port called "RF Converter." You can use Neo Geo or PC Engine AV cables with it. I couldn't read the Japanese in the picture above but now that I'm looking at a picture of a Titler I can see it more clearly:
The Vs. arcade systems have unique palettes radically different from the home Famicom/NES. The PC-10 and Titler RGB PPUs have a palette choice that is not an ideal match for the regular NTSC PPU in the NES/Famicom. But the colours are close enough in most cases: Regular Famicom on the left, RGB Famicom on the right. (From my RGB page: http://www.disgruntleddesigner.com/chrisc/gotRGB/index.html)
I would enjoy this quality only for experimental purposes. I don't fancy those clear pixels in gaming conditions.
I don't remember them being so clear, I remember the classic arcades (with the exception of Neo Geo) having a composite quality signal that somehow blended everything.
With the exception of a few odd old arcade boards, all arcade boards gave a RGB output. The monitors may have been utter trash and would end up with blooming and unfocusing but it was still RGB. The RGB mod is good but it's not 100% and there are a few games which either won't display properly and become unplayable or show very light greys as black or even white, still for most people it will work fine.
Thanks for the replies. I'm confused about the sharp twin famicom. Can it output rgb with a neo geo rgb cable and no modification? thanks
