Modbo on PS2 V4 GH-013

Thanks for the tip man that's looks eye killing points i just fitted a mobo 760 to a v10 silver and done a la fix and worked first time.

And i used to try and do these mods on a v10 years ago but always messed up the boards but now i can do these its cool.

 

i apologize seemlesslies. In my experiance with ps2's (V5 and up), the G and H points were needed. There were a couple diagrams that was missing the "H" point with a V7 and when it wasn't connected it wouldnt boot up backups and after that experiance i always pretty sure NTSC-U consoles needed all points. Thank you l_Oliveira for helping us out, i'm going to edit the diagram so this wont happen again.

 

Your welcome dude . Yeah when i was 14 i thought i could install a ps2 modchip so i bought a "Magic V 50k" and had a cheesy radio shack iron with a huge tip i messed up my v7 on those points (Never knew how to remove bridges then) lol.

 

Well I'm having problems again itit seems that it able to boot into The Matrix menu and it is able to play original game however I'm having issues playing backups I've tried running burn this from 8x to 4 x to 2 x I'm going to try a different game but if that doesn't work when it's working like normal but not reading backups then I read it most likely my A,B, or I connections or I have to adjust my pin on my lense however it's just a copy of dot hack 1 I did torrent it but I own the original it wasn't the full 4gbs so I wondering because it didn't takw up the full disc space if that's the issue. On game boot up it does say 1.93 v matrix

 

If you can play originals from other region, your problem is NOT the modchip.

 

Their my same region sorry didnt mean to confuse everything has been ntsc check my solder one might have been a little lose however still not working with backup

 

I suppose it could be my cds or how im burning them. Their 16x dvd+r and you're sure connections G and H are not causing an issue because I removed them? I made sure not faulty connections, and normal discs are working.

Gets the red not a ps2 or ps1 disc.

Burned the games with alcohol 120 in ps2 burn one at 8x one at 2.4x and the other at 2.4 different game. Removed the options for buffer underrun. I'm not sure the brand of DVD's I'm using removed it a while ago so I'm not fully able to rule out the DVD's tired forcing NTSC in the bios didn't help.

I saw something about getting out my multi meter and changing my pin charge of my reader?

 

Just find a original game from a region different than your own and have it tested that way.

 

I don't have a different region game laying around at the moment it might be something I could get later, but that doesn't really help me now sadly.

 

It does help. It would make you sure if you're burning the games wrong or if the modchip is not installed properly.

You don't need a game to keep. Try to borrow one from someone !

 

I'm going to rage a little, but Oliveira you're dead wrong in telling me that H or G was not supposed to be connected because they are. Once I went back and put those on it worked just fine so I'm not sure where you were getting the idea that you're not supposed to connect those, but on a V4 no gap it doesn't work without H or G just fyi thanks for everyone's help going to go break a wall/window/door or two.

 

I was VERY specific ! I said NTSC U/C.

Oh wait ... It's a CRAPPY piece of clone modchip, no ? A real matrix will work with just A, B and I connected to the mechacon. No problem.

 

------^
l_oliveira, I'm not trying to throw you under the bus. I know your very experienced with PS2's.

 

Well it's a modbo so you're saying it's crap I suppose? The fact is though that for a NTSC NA on a V4 Non Gap Bios does require both H and G by my own personal testing. Just keep that in mind next time you give someone advice that could waste 10 hours of someones time, and thank you Zer0 for all your help I'm sorry I didn't listen to you in the first place.

 

I am saying it's a clone with pretty poor support. These aren't the same thing as the original chip. By the time the original chip disappeared from the market I was already working with XBOX360s.

So how am I supposed to know that a crappy clone requires all wires to be connected to work ?

Edit: While at it, check these:

And judge if I was giving you poor advice...

Edit2: All consoles up to "V7" on PAL or non Asian NTSC regions work great with just A, B and I wire connected (of course I am talking the original chip here) just check the schematics at sksapps. I am sure the Chinese who made the clone chips have modified schematics that are specific for their clone product, but my only mistake here was not point you to the proper place for directions.

But then again, ONE OF THE MODBO chips work with the ORIGINAL Matrix wiring.

You have no reason to be incensed with me.

 

I do appreciate the help however you were talking about a similar product, but not one that was the same. I'm not denying I'm out of the water in this area so I was asking for help, and you were nice enough to give it, however I am a little upset that I spent so much time troubleshooting and issue that could have been fixed rather easy with just putting those two connections on. Maybe in the future explain that it worked like that on the Matirx however it might not work 100% the same on the Modbo. I was a little snippy because I spent so much time, but just assuming things doesn't always mean that it's correct.

 

Look this diagram and ponder if I am at fault for you losing 10 hours at that PS2:


Thanks for your understanding.

 

If you noticed that says V 1.1..........................

If you go back look for the V 4.0

http://www.sksapps.com/diagrams/ps2/Modbo4/V4.jpg

There is the correct one you are looking for, and it clearly shows points G and H even going as far to state it requires H for NTSC US and Jap.

I will admit fault for not posting that I had a Modbo 4.0, but I think most people would have figured that's what I had because that is generally the most widely accepted one from all the information I have found. However you're the one that has a quite a bit more experience then me, and if I was offering help and I wasn't sure which model Modbo they were using I would ask before giving advice.

 

The modbo 4.0 is the best chip (clone) just right behind the original (Saves settings etc). The Matrix team stopped production of their chips for a good while now and if you were to find an original, you'd be paying a premium.

 

I know this is a few months old but wasn't able to get my hands on a v4 no gap until now.
Tested a Modbo 4, Modbo 750 and Modbo 745. All three have the 1.93 firmware. All had issues loading backups, giving red screen, not ejecting drive.

Had one last Mars Pro laying around and gave it try

System is booting every backup, psx and PS2. No PAL2NTSC support but working great.
I'm able to use dev1 and 2.
Anyone wanting to install a modchip to a v4 or lower might want to try a DMS4 clone chip. Mars Pro, Super 7 or M7
