Hi, I'm looking for a diagram for the GH-015 PS2 motherboard, I've downloaded the scph-30000 series service manual as well as the scph-50000 series one and neither mention this board, the scph 30000 series service manual mention the GH-010 and GH-012 I think. I'm looking for it because I'd like to find some good spots to get at the R,G,B H-Sync, V-sync, and whatever other signals needed to solder a VGA output since my television doesn't support composite, nor s-video.
I found this thread: https://www.assemblergames.com/foru...S2-Hardware-Documentation-and-Service-Manuals Which had the pdf I wanted except that megaupload is dead EDIT: Nevermind, Pool7 reuploaded some good links to megaupload in that thread on page 3 Also, I noticed I should have put this thread in the modding section, sorry. To do a VGA output, should I be using RIN, GIN, BIN, HSYNC_IN, YSYNC_IN, or ROUT, GOUT, BOUT, HSYNC OUT, VSYNC OUT? Another question, I've heard something about sync on green causing problems or something, besides soldering these points and connecting to a vga port is there anything else I'd have to do?
The PS2 natively outputs RGBS (via SCART/JP-21) and RGsB (Sync-on-Green). By using RGB SCART cables or Component cables and a converter, you can use the PS2 over VGA. I found this RGBS/15KHz RGBHV/RGsB to VGA (31KHz RGBHV) converter on eBay. It also supports component video to VGA conversion. Using the converter I linked above, you do not need to solder a VGA port. Also, the VGA output is software controlled so not every game supports it. RGB and Component is supported by every game. If you want a cheaper, and maybe not as good option, you can look into those $60 SCART to HDMI converters.
Thanks for that info. I was actually looking into converters before making this thread, but decided against buying one due to a combination of being poor and wanting to learn a little bit. Since VGA output isn't supported by every game, I could add both a vga output and component output, to switch between them I'd solder a switch from pin 32: SONGEN to ground. To switch to VGA, I'd flip the switch on and to switch to component I'd turn it off. This would work, right?
Component cables are dirt cheap so there wouldn't need to be a reason to output component over the VGA port. Then again, a good cable costs more than $20. There is an official VGA cable and came with the official Linux kit. However, it is RGsB and not RGBHV. Not all VGA monitors support RGsB. Helder sells the male plug for PS1/2/3 cables over in the marketplace if you want to make your own cables. You don't need a switch since RGB and YPbPr output modes are controlled by the PS2 operating system. To swap between the modes, simply go into the system settings and swap the video output to either RGB (RGBS and RGsB) or YPbPr (analog Component video). The AV Multi-Out pins used for the Red, Green, and Blue lines will output Y (Green pin), Pb (Blue pin), and Pr (Red pin) when swapped to YPbPr mode. Because of this, PS2/3 Component cables DO WORK on the PS1 but will output RGsB instead of YPbPr. Be warned, PS1 games and certain PS2 games will output a 240p image. Some HDTVs have trouble with 240p. Most VGA monitors require a 31KHz RGBHV signal with a minimum resolution of 640x480p at 60Hz. Many PS2 games output 720x480i/576i and will not work on most VGA monitors, along with those 240p games. The PS2 System Menu is also 480i. If you are willing to wait, a true digital HDMI mod is planned by another user on this forum. It will bypass the DAC creating analog video and analog audio so you would get a true digital signal sent to the TV without Digital to Analog conversion, unlike those cheap AV Multi-Out PS2 HDMI adapters that do Digital to Analog to Digital conversion.
