Try to decrease the sound volume one step lower by multimedia keys.

DTC demo detects CRTC1. Probably it's already fixed.

If you can explain how they make this special mode, then i will try to implement.
Or at least link with technical details.

Support for disks with protections is in very early stage - don't expect much. Use patched/modified version without protection.

There is always chance to use either analog audio or TOSLink if your TV is picky.

It's exactly protection. cat is not a simple printing.
Many disks exploit the cat to hijack the execution to its own code - that's why you may see complete different reaction than just catalog printing. Its own code also may include protection. This disk i known to have a protection.

Ok. You are more professional than me. Project is open sourced, so you can provide the fix.

P.S.: Explain then how for example DemoIzArt cat does that things and even divide the screen to 2 areas. And many other demos/games giving animation by cat.

i think the best for cat'art is sylvestre on the previous link (point 4 for car code)

as i say the cat'art is caracters that can move cursor and write on screen in the catalog sector 0 to 3 track 0 (data disk)

see on cpcwiki.eu

"basically it uses the ASCII (&20 to &7F) and control codes (&00 to &1F) to display text on the screen instead of a list of filenames. No m/c or BASIC can be run using CATart. It's more of an artform, rather than a programming language."

demoizart for example, on Screenshot at first line you can see

00 41 a valid entry
0F 00 PEN 00
0E 00 PAPER 00
04 01 MODE 1
15 deselect screen

etc

It's possible the bug is in FDC code currently developing by Szombathelyi György.
He is aware of this problem. And if it will be possible, then it will be fixed. Same goes to protection support.

Is there any game/app/util using CRTC's interlace mode?
Note: there are some demos like Batman Forever claiming to use Interlace mode (picture on the end). This is not interlace mode - it's just picture with every other line shifted by 1 char left/right WITHIN the same field then swap the HSync offsets on the next frame. So, it's just flickering picture - has nothing in common with interlace mode. The same trick is used in Perfect Pix Painter and Dream Pinball. All of this is NOT interlace - not even a bit!

What i'm looking, is real interlace using CRTC's interlace mode (Reg8 = 3).
I wonder if there are productivity/professional apps using high vertical resolution?
