I thought china was NTSC except for Hong Kong? I would’ve figured being a former british colony they’d have been blessed with SCART sockets.
oops, my bad.
No, from what I’ve been told, China is PAL. For instance, when we moved into our apartment, there was a Korean TV descrambler here, but it was from Korea, and we were told it wouldn’t work on Chinese TVs. I know Korea is NTSC, so that only leaves PAL and SECAM, and I think SECAM is exclusive to Australia.
Putting money aside for this!
well i’ll be getting one of these
Thanks! I’m really trying to do a bang up job!
Spent a bit of time getting more intimate w/ the timing characteristics of my USB host processor. It appears I can run it 4x faster than currently. I’ll try throwing a faster oscillator on this weekend so I can get some new button latency data next week. Theoretically, at 4x, worst case lag would be in the way of 10ms, typical being more like 5ms, and best being sub millisecond. That means worst case is still less than 1 frame of input lag. Quite acceptable, IMO.

What language are you doing the code in? Are you just programming something you’ve already designed or are you doing Hardware description? This is just curiosity, btw. I have no valuable feedback for you. I’m just a college EE undergrad trying to figure out what you’re doing.
undamned, check Pm <.<
C. Just programming a board I designed. Haha, I haven’t looked at HDL since college! 
How far in school are you?
@ Maijin: Replied!

I figured that would be the case. I’m a first year transfer right now (senior by units, junior by time left.), but I have to take a bit of HDL for the next three quarters. My senior project is most likely going to be built off of an HDL development board and probably just expanded through the board’s expansion slots, but when I saw that you were cutting out some code to reduce lag, I was curious if it was a Description issue or a programming issue. Now I understand, thanks!
I’m so damn curious to take a look at this baby. You had it running at Devastation, right? No pics? 
Pics are on post#24
Is there anyway to have component available for this? The reason i ask, people are tired lugging around big ass heavy crt tvs at gatherings/tourney. Being able to hook this up to a monitor would be a huge convenience IMO.
Im also really curious how much one of these will cost. Im hoping the prices will be more on the MVS consolize range then the Atomiswave consolize systems.
Thanks, I somehow skipped that post - actually I just noticed I skipped a LOT of posts, WTF?
Also just found out the 1st post was updated with pics! 
The CRT thing is more about lag snobs. VGA out is easy to get for JAMMA.
Sounds fun! You should put up a thread on it when it’s done (whatever it is)
I’d love to have component out, but at this time I’m not putting much focus on that aspect of the project. As rufus mentioned, (non-hd) CRTs are the display of choice for lag free play, so I’ll leave it up to the user to upscale the RGB to whatever they want. Upscalers and TVs that upscale will introduce some amount of lag that I don’t want to be responsible for.
Holy cow! I just looked up a cosolized Atomiswave! $829? Who pays for this nonsense! I could buy a nice cab + Atomiswave + more stuff for that! Short answer: no, this will not cost that much!
Small update:
4x oscillator is running fine, just need to take it to work to check new input lag specs.

yep, i’m in for one as well =) i been trying to get a candy cab but have no luck so this seems to be the next best thing!
SECAM is mostly france and eastern europe. Australia’s PAL.
Just checked Wikipedia, China’s definitely PAL. Shocked they don’t have SCART. Weird.
SCART although designed primarily for PAL was a European development. Scart did appear in the US called EIA Multiport but never **
**became popular. Scart was a means to have a universal A/V connector for the European market, where before each Country had there own standards in Europe.
Scart was introduced to Japan as the Euro A/V or Euroconnector. China being a closed market to outsiders in the late 70s, 80s and early 90s never adopt the standard. I also believe at the time Chinese homes all did not have a Television as standard.
Will the UD-CPS2 work with Grey B-boards? I just did some Googling and one page suggested that Green and Blue boards could share the same type of A board, but the Grey and Orange required a matching A board.
IIRC, this is true in the case of green and blue boards. We used to run a green Japanese Marvel vs Capcom in an American B board in the arcade I worked at (yeah, it was illegal, but I don’t think they cared).
I hope compatibility is less of an issue with the UD-CPS2. There’s a Alpha 2 Grey board for sale and I want to put in an offer for it.
