Arcade Lifestyle / Re: And now for something else: NES RGB mod
« on: July 14, 2015, 04:52:52 AM »
technical background on NESRGB:

- the NES PPU chip only outputs composite video (Playchoice-10 is the only PPU that has RGB out, but the color pallet is not the same as NES, some games have slightly different colors.  e.g. brown where it's supposed to be more red).
- the FPGA on NESRGB sits between CPU and PPU and intercepts writes to PPU
- it forces PPU to output most of the digital data (color vectors) on the PPU's EXP pins (these pins are normally connected to ground!)
- only missing data is if color belongs to foreground, or background.  To force that data out of PPU, the FPGA will force picture to black and white palettes. Then analyze output from composite video which will tell it if the color was foreground or background!

Now NESRGB has all the info it requires (color and sync information) in pure RGB.  It can then output the RGB, or convert it internally to S-Video or composite which is much cleaner than the old NES PCB which has a lot of added noise.

It was a huge breakthrough that occurred on NESDEV back in 2013.  It was Tim W. who made the NESRGB the commercial success it has become.  If this wasn't for this work, a lot more PC10 systems would be killed for its RGB PPU.

Scr33n: can you keep a log of cost? It will be interesting for people to see cost to make one before they commit time and effort. I'm sure it's more then buying ready made but how much more.

Yeah, power almost never goes out here because all our cabling is in the ground instead of the ancient poles still used in the USA. Only the biggest transport lines are still up in the air here (although at some spots, even these go underground today)....well that's one advantage of soft ground...

When was the last time you were in North America?? All new housing developments for the last 3 decades had everything running underground (power, TV, telephone, and now fiber). Only old areas with 100+ year old homes have wire above ground.

As for power for sump pump, they do sell battery backups and are common items to install when your sewer lines in the house are below the mains under the street.

The most important thing to do when tackling major construction is to follow the codes and building styles of where you build. Things that work great in Texas might not apply in northern Finland! (Eg water heater outside, ducts running in the attic, etc)

Hey Bruno. Apart from the few tweaks / repairs and never ending maintenance. Is it safe to say the build is now complete?

Hey Bruno,

thank you so much for giving this cab to me...

!?!?!?!  Bruno, why would you get rid of such an awesome game??

Argggh! The Galaxian Theater doesn't boot anymore this morning!? :shock: What's wrong?  :ghost:

April fools!! (right?)

CRT projectors can be rejuvenated but of course that won't solve any burn...

Some also believe this shortens the life of the CRT.

Don't get me wrong. My new astro city has a 29" MS9.  It'll be a cold day in hell before I put an LCD in there. But one day in the future I might have to.

When the projectors are refurbished and have tubes with no burn in why would he not have the results he wants.
You say refurbish the sony's will be to expensive but have to prepared for spending  thousands to go digital ,goinging with the sony's wil be a lot cheaper and are optimal for the game. (think curved sreen and blend)

There are parts of a CRT projector that can't be refurbished without purchasing another CRT projector and doing a transplant.  That's what I was trying to explain about not getting the results you want.  This is no different than doing a chassis transplant on a CRT monitor.

Wow! There's so much misinformation here that its scary. Here's my $0.02 on what was said and what I believe to be true:

- "we should all switch to LCD 4k resolution but don't because we want original picture" - truth is LCD is brighter than CRT tube for much longer. CRT tubes dim over time no matter how many cap kits you do on it. LCD has more than enough resolution to reproduce the CRT scan lines (which is actually what you love about arcade CRT). The reason why people stick to CRT is aspect ratio. Good luck finding a 4x3 25" LCD. They're all 16x9 and is the main reason many haven't switched. Classic games were made for 4x3

- "switch to LCD / DLP" - depends on which technology you use. Please don't use single chip DLP. Many people are still sensitive to the color wheel technology, they see color rainbows on white line edges. Also good projectors are EXPENSIVE. You want a projector that outputs same lumens at all colors (cheap ones are only tested at white and even cheat by adding a clear filter for white on the color wheel!)

Bottom line, eventually you will need to go to new projector as cost of bringing these beasts back to life wouldn't make sense and even if you do, you won't have the results you want. On the other hand if you do go LCOS, 3LCD or 3xDLP prepare to spend thousands for something worthwhile for this beast. But you will not regret it.

so am I the only one that noticed Bruno always has what seems like a fire extinguisher beside him at all time??

What you need is a 31khz -> 24khz or 15khz video scalar.  It will work with all VGA input and give you the most pixel perfect display.  You can then use a different solution for controls.

Oh!  I wasn't aware it didn't work initially. Hmmm worst case scenario Bruno can mame it! Oh yes, street fighter 2 on a super massive screen! :shock:
