Tokyo City Nights Jar. Hi, It's little bit late, but in the image bellow you can find correct GH-52-51 diagram. I have tested it - it works. I think you have probably made bridge around SX point - it's hardest place for soldering on that board.

Don't be affraid of of the 7701 number - mine was 7704, last digit is for the region code. To Bootlegninja: the diagram you provided is very dirrerent from GH-52-51, despite it's labeling. Don't use it for that motherboard. Hope it will works for you.

Note that disk spins after sucessful power on, that doesn't actually mean that motherboard is working.

I want to play import PS1 and PS2 games. I've looked into soft modding, but it doesn't give me the functionality I desire (ability to play PS1 and PS2 games from any region using the original disks, that's all I want), so it looks like I need to install a mod chip. I thought I'd run my thoughts past you guys! I'm thinking the Modbo 4.0, this seems to be a popular one, and from what I've read, it has the region-related features I want. Would this be a good choice? As to installing it, my PS2 is a PAL (Australian) SCPH-50002, from what I've read, it has a V9 motherboard, so is this the diagram I should be following?

Installing a ModBo 5.0 Chip In a Playstation 2. Tools: ModBo 4.0/5.0 Chip. ModBo 4.0 Install - I'm looking for a modder based in Ireland, UK or Europe User Name.

It says 'USA' on the diagram, so is installation different for my PAL console? Also, I see there's some alternative solder locations for the wires that are normally soldered to the legs. This sounds appealing to me, since soldering to the legs sounds really fiddly, and there seems like there would be a strong likelihood of accidental bridging, but is there a downside to soldering to the alternative locations?

There were a few things I was wondering: 1) Apparently modchips can burn out the laser, is there anything I can do to prevent this (something about a 'diode fix'?)? 2) Will NTSC games automatically run at 60Hz and PAL at 50Hz?

3) When the mod chip loads up an import PS1 game, it's using the console's PS1 hardware, just like a stock PS2 right? It's not emulating the game? 4) Does a modded console function essentially the same as a stock console? I can just pop the game in and it loads up, nothing more required? 5) Some guides mentioned scratching lacquer off the points you're soldering to. Would this only be necessary if you can't get the solder to stick to where it should, or is this the case with all PS2s? 6) How badly can one screw this up?

It doesn't seem massively complicated to me, but in case I accidentally create a short or solder to the wrong point or something, does my console die the moment I switch it on, so is it possible to go back and correct the problem without issue? 2) Will NTSC games automatically run at 60Hz and PAL at 50Hz? Color format switches along with Hz also, unlike other consoles. Standard PS2s support the same in-game video modes and cables worldwide*. It does not associate them with either console or game region.
