I get a black screen with my CRT using component cables 😿

For ease of debugging, the current code supports both loading from sdcard as well as loading from the second sdram module. If the second sdram module support is enabled, analog output from the I/O board gets automatically disabled (they share the same pins after all).

But I don't use a 2nd sdram module.

The core must be rebuilt to use the pins for analog out.

Basically just this line has to be removed:
https://github.com/RobertPeip/PlayStati ... on.qsf#L54

Keep in mind that analog out isn't fully polished yet anyway, so if you really need it, it's best to wait some more weeks.

Oh I see. The dual RAM option has been kept even if we don't need it. Oh well, I'll keep testing it on my HDTV and wait for analog out.

It works with direct video if you’re using a CRT. That’s how I use it.

It works for me but a little out of sync on a Trinitron CRT. Does anyone have any particular resolution in mister.ini for the PS1 core?

Edit: [PlayStation] composite_sync=0 did the trick

Super glad this is/will be supported. Will it work with native 480i?

There's some kind of sync problem with Direct Video, at least for me. But at this stage it's to be expected. Don't worry, and have patience.

Yes, the developer is still using it, which is why it was implemented in the first place, as it makes it easier to debug the core when loading games this way.

Peip has said he might reenable the analogue IO board for the next release. There might be a way to make it an option whether it uses SD-RAM or the IO board in the core, not sure.

As i will use the second sdram for a while when i add sound, i will not remove it in the next weeks.
Expect Analog Out some time early next year.

Until then, debug builds will not have it. You can do your own build, but i don't want to distribute 2 debug builds for now.

The core is currently working with direct video to 15 khz TV? or 31 khz VGA?

15 KHz TV. But there are some flickery lines showing up.

I also noticed the image is horizontally shifted heavily to the right.
