Sony DTL-H1000 memory soldering problem

Maybe, but if you have a good pickup they are not generally that critical.

Is this actually a KSM-440BAM you removed from a PSone yourself, or one you got from ebay? If it came from Ebay, it's probably very poor quality.

 

Best fix for you would be to get a broken slim PSone and swap the laser it has to your DTL-H1000.
With a original BAM laser out of a PSone slim (not the eBay lasers which are probably very very poor quality)you don't even need to change the BIAS and GAIN pots anymore,even if previous user did that.(I've tried that and every game I had,my old 1002 would load them quickly without any FMV skip)

 

Yes, it is BAM from ebay.
I have PS One in very nice condition (not opened yet) which runs all games, so I don't want to use it in DTL.
I will go to ebay to buy broken PS One.

Another thing - why old laser unit and new laser unit don't want to read NTSC-J games on CD-R?
And last - why the screen on my TV LCD is moved to right side? I'm using RGB cable.

 

I have no idea - since a DTL-H1000 is a Japanese debugger, it absolutely should be able to read NTSC:J CD-R media.

I have seen a couple of them that had the later SCPH-1000 BIOS that would reject non-Japanese discs, but they would still read NTSC:J
disks (both original and CD-R) without problems.

You have a TV that doesn't like the PSX. Some of them do that.

 

It could be bad media, bad image or a problem with how it's burnt. My gamecube could only read discs burnt at 4x speed, using 1x or 2x and it won't read them (it generally only worked with certain brands of media and certain writers too).

If you can rule out the discs by trying them on another Japanese console with a mod chip then the motherboard may have been adjusted and no longer reads cdr's or it might have been replaced with a retail one.

 

In those cases, it wasn't a problem with being able to read the media - any non-Japanese disc (original or CD-R) would kick you back to the shell. Japanese discs (either original or CD-R) worked with no problem, and if you burnt a CD-R with a US or PAL game on it but the licence data from a Japanese one that would boot too. It would also boot anything if you used Caetla to bypass the shell in ROM.

Swapping the boot ROM with one from an early SCPH-1000 fixed the problem and allowed it to boot anything. I assume that when they were building the debugs they just took boards from current production and changed over the mechacon CPU for a debug one. It looks like the board this one was based on was from the later production that had the territory check.

 

There are two DTL-H1000 revisions, one is SCPH-1000 based and the other is SCPH-3000 based.

I'm not sure it's the license check though as he says it's Japanese games on CD-R that aren't working, I was assuming he has tried a 1:1 copy of a Japanese game where the original works.

 

How do you figure that? All the ones I've seen looked like SCPH-1000s - PU-7 boards with a S-Video out socket. It's just that some of them had the original "no version" boot ROM and some of them had V1.1, just like the retail units.

Yeah, I was just pointing out a possible issue - a lot of people tend to assume that debugs will all boot anything you throw at them, which is not always the case.

 

I've not heard of v1.1 in an SCPH-1000, only in an SCPH-3000. So if they were pulling motherboards destined for retails and replacing the subcpu then it would be 3000.
There are different revisions of PU-7 and I don't believe the change over to SCPH-3000 coincided with the switch to PU-8.

Some sources claim that early SCPH-3000 didn't have the region check either.

Sony are consistently inconsistent on naming.

 

Yes, there were definitely SCPH-1000s with the 1.1 boot ROM in them. I've had several of them, and the guy in this thread had one too:

http://www.assemblergames.com/forum...-v2-1-chip-install-(16F84-04-P)-PS1-SCPH-1001

I can also remember when they came out, because the same update also disabled the audio menu swap trick and resulted in the development of the "black screen" swap, with resulting angst about which SCPH-1000s were the "good ones".

Every SCPH-3000 I've ever seen (including the very early ones which were still using the PU-7 board, although without the S-Video socket) would only boot Japanese discs.

 

Seller from ebay.com send me another laser unit.
Now my DTL-H1000 works fine I need to find a solution how to burn a NTSC-J or NTSC-U games and check it on debugging system. I have only few games in PAL which work OK.
Thank you guys!
