Hooray for peer review.
Related: if you guys have write-ups/resources on CRTs & PVMs for the OP, lemme kmow! I'd like to update it to be more inclusive of all the great options available.
Here's some topics that I feel are worth expanding upon:
- Better screenshot/video comparisons of RGB vs lesser video connections. I could offer direct captures for various systems myself and already have a few on my
XCAPTURE-1 review page. The one caveat of any of my captures, though, is that they would come with 4:2:2 color sampling that doesn't accurately reproduce the brightest greens or darkest reds on certain sources. (You can check the chroma subsampling section on my page to see example screenshots.)
- Instead of just linking to Fudoh's main website and leaving it at that, add in an additional link for his
Micomsoft scaler cross-comparison, which is probably the most useful article on his website. It's fairly up to date, corrects a few pieces of info from his previous articles, and breaks down the strengths and weaknesses of each device when compared to each other. It also even names a few worthy alternatives to Micomsoft's product line, even though they're not expanded upon in detail here.
- Links for places to buy upscalers. Solaris is the only place I know of where you can get them brand new from a reliable retailer, but second-hand markets like eBay and especially
Yahoo Japan might be worth a mention. (In fact, if anyone has recommendations for third-party courier services that can deliver YJA items internationally, that would be worth a breakdown in and of itself. I'm not familiar enough with the fees for different services to give a good recommendation personally.)
- A clarification that only the original model SNES/SFC, and not the newer miniature model, outputs RGB out of the box. Perhaps add brief comparisons and pros/cons of system models in general (e.g. putting up with or fixing Genesis 1 jailbars / Genesis 2 audio, early SNES vs 1-CHIP SNES vs SNES 2 etc).
- A note that the PS2 and PS3(?) also support RGB out of the box, although it's only somewhat justifiable on 480p PS2 games and hardly at all justifiable on the PS3.
- As noted upthread: a brief breakdown of the current NESRGB mod and its pros and cons. FYI,
graphical glitches with it are fairly uncommon but important enough to note IMO, and if you keep up with the thread on the shmups forum you should be familiar with a few of them, one of which is present on a firmware revision that's not even a month outdated. Tim does squash these bugs pretty quickly as they are found, and it is possible to flash the board with new firmware as he releases it, but it still requires the end user to have some specific hardware to do so, and astute consumers who are unable to mod the system themselves should ask their supplier to add an appropriate connector to
the designated area of the board so that it's more plug-and-play ready for a USB blaster.
- Information on sync issues and what can be done to mitigate them. IMO, when modding a console for RGB (or S-video or whatever else), I think it's good practice to make sure that every designated pin on the console's AV port is wired to what it's designed for. That means that when modding an NTSC N64, for example, the user should make sure that the +5V, composite video, and composite sync pins are all wired up, even if some set-ups don't technically require them all. Some RGB cables pull their sync signal from the csync pin, others pull their sync signal from the cvideo pin with no processing, and others might pull their sync signal from the cvideo pin with some kind of stripper in place that requires the +5V pin to supply power for it. So, I think that by taking care of everything on the console side that you can, you can reduce incompatibility issues. (I'd like the experienced modders among us to chime in on this if they have additional recommendations.)
- Perhaps a breakdown on all popular retro game options: CRTs (15khz professional monitors, 31khz professional monitors, consumer TVs, consumer VGA monitors), upscalers (with specific recommendations for more worthwhile options like the XRGB product line and warnings about cheap converter boxes from China and whatnot), SCART-to-component converters, emulator boxes (lol), etc.
- Perhaps also an additional breakdown on the hierarchy of video signal formats in the first place, from best to worst: HDMI/DVI-D, VGA/DVI-A, 31khz YPbPr (component), 15khz RGBs (SCART), 15khz YPbPr (component), S-video, composite video. Points of interest would perhaps include why one signal is better than another (e.g. analog RGB isn't
theoretically worse than digital signals, but interference and signal loss are more of a factor in analog video in real-life circumastances, hence the importance of proper cable shielding) and what the user would need in his display to actually net the benefits of one signal type over another (e.g. the superiority of RGB over YPbPr isn't as much of a factor if the display can only handle limited range 16-235 RGB in the first place AFAIK, not every TV or processor handles VGA very well, SCART sockets on modern PAL HDTVs are kind of junk and would still require an external upscaler or linedoubler to get good quality, etc).
