Modbo 4.0 - On a V4 PS2

[emu_kidid]

I have installed a Modbo 4.0 identical to this one here: http://www.covetime.com/modshop/prod...roducts_id=125 on a V4 Australian SCPH 30002 GAP bios (not that it matters) PS2.

I've done the "H" point too which it claims is required only for USA/JAP consoles but I've seen places that it's required for these consoles too.

When I start the console up, I'm greeted with a nice black screen and nothing else. I've checked-doublechecked-etc all my points on the BIOS but there's nothing wrong there. I even tried with a controller plugged in as suggested online, and I cannot get to the boot menu.

The console will boot up if I disable the chip (hold reset) and it will read DVD-R as a PS2 Gold disc in the menu but it will not boot it up for obvious reasons.

My Real question is.. is this modbo 4.0 a clone that won't work on this V4 console? The reason i ask is that i've seen it advertised as a "V3 - V18" modchip, then I've seen it listed as a V5-V18 modchip.. what's the real deal here??

I have a v4 Fat PS2. Honestly I don't think I have a mod chip, but I could. A
friend put it together for me since I didn't have the internal HDD to add along
with the console.

That I know of so far on this thing, all of the main SNES, NES, Genesis, etc are
all loadable thru ULaunch. I mostly use my HDLoader thru ULE, so I'm not too
sure what it is you're having problems with.

If you are using an internal HDD, then to load games onto that you would need
a SATA to IDE cable set, and do it via the pc(this is how I get them on there).

But like I said, I'm not too sure what it is you're trying to accomplish with your
console.

Lmao emu_kidid I had that same exact problem before with my slim. No matter what I did I just had a black screen on boot. But after seriously the 7th time resoldering the bios points I got the chip to fully work. Honestly what I did was put the points 1 by 1 and checked if I still had any video after every one that I tried. AFter a good 3 hours The ps2 was up and running. The only problem I had was that after I put it back toghether my ps2 reset ribbon broke on me and I had no way to turn it on! Witch sucked for a while till i bought one off of ebay for 2 bucks. Now Im playing happily on ma chipped slim. So yeah just resolder the points by the bios is all I have to say. Also I want to know what guage ur using for your wires. Before I was using 28 and I bridge alot of bios points. So I resolded with 32 gauge and I did em 1 by 1 and worked perfectly.

wtf?

CronoBJS, thanks. I resoldered it ALL today and still nothing. It booted up first try, then I powered down, tried again and it's back to black screen. It's really odd. I'm starting to think that it's not meant to run on a V4 console or something.

Does it black screen when you have it all pieced back together? or have you tried hooking the bare mobo up and running it? I say this because the metal piece that is screwed to the mobo can short out the bios points on the modchip, thus giving you the black screen. You can also try covering the chip in electrical tape.

*** After doing some research I think your right and its only V5-16 compatible.

Might I suggest the Modbo 760. http://www.covetime.com/modshop/prod...roducts_id=131

I've installed them before and I also have the Modbo 745 (Same chip but different shape mainly for fat V3-10s) installed in one of my systems and it runs just like a Matrix Infinity. Just don't try to use a MI update disc and your good

Yeah, I'm thinking it's V5 onwards only, it would explain the inconsistencies I'm seeing. I have tried with the ps2 in pieces, checked every point for signal even when the console was up. I'll grab a Modbo 745 now.. what a waste of 5-6hrs :|
