Did you use the same disc on the the 1001 and 5501's? And was it a retail disc? And just with the standard BIOS ROM, without any expansion ROM plugged into the connector at the back of the console?
I think, normally it shouldn't 'scan' the whole disc. Or only in unusual cases, like using a patched ...

Re: Launching an ISO (PS-EXE) from the command line
Yes, but that's bugged in the current version, sorry.
If you just want to load a recently used disc image or exe file, use Alt+F and select one of the recent files.
Or simply use Ctrl+R to load (or reload) the most recent one.

I didn't notice that the video was shaky - but all the best healthwise!
Are you sure that the debug console is faster? The missing SCEX check could theoretically make things slightly faster, but that SCEX check happens before displaying the PS logo.

Removing line 36 and still getting the same error in line 36 makes no sense.
Or only makes sense if you don't know how to edit the source code, and save the changes.

Are that the SRAM data lines, D0..D7, and all eight of them looking like that?
The falling edge looks fine. The rising edge not so. But I am not sure if that's wrong: If the cpu is neither reading nor writing data, then the databus may be floating high-z, which could look about exactly as on your ...

Thanks! Good to know that it isn't completely incompatible with win11.
Maybe it was a bug in win11, and microsoft has fixed in newer updates, or maybe it happens only for people with more than one monitor.

Re: VRAM Object List blank in Windows 11
Hmmm, I don't why no$gba works better than no$psx, I thought they were both using the same GUI code.
Next no$psx update will use a "list" instead of "tree" in the vram viewer, maybe that fixes the problem (but the filesystem viewer would probably still have the problem).

Is this a bug? Here's how lines appear in NO$PSX compared to other emulators. Lines where (x1-x0)>(y1-y0) become dots.
Yes, that's a bug. Real hardware should look more like the other.png. It's sorts of already fixed, but I don't know if or when I can find the patience to upload updates, I am a ...

Re: Sony DTL-H2000 Troubleshooting, Info, Setup, Parts & Help
I think the unspecified new PC setup is just wrong, like using a power supply without -5V, in case the DTL hardware needs that voltage. Or having forgotten to properly connect the DTL audio to... whereever it is connected to.

Re: scph-1000 bios mod question
I would like to clarify two things.
The kernel clone is freeware you can't buy it anywhere.
Xboo refers to the "boot exe files from parallel port" feature, which is only a small (but perhaps the most useful) part of the kernel.

Re: Ordering Tables
Using two tables allows the CPU to start updating the table for the next frame while the GPU is still busy with rendering the previous table. That gets you a higher framerate.

Re: PSX.EXE that are bigger than 2MB in size
That seems to be a kernel issue. The stack is near the top of the standard 2Mbyte RAM area (during loading, and also after loading).
It might work when changing the load address in the exe header to the upper 6Mbytes (though I am not sure if all kernel versions have the extra RAM enabled in the ...
