@Georg

I think there i some memory to be saved if AmigaOS had a global font cache, but that's is different angle.. how many programs use the same font.. how many times is duplicated in memory.

I'm not sure what you mean with native font rendering. But you still used freetype2 because the ~native AOS4 font engine (bullet "standard") "ft2.library" is using freetype2. So freetype2 is used either way, either directly by app or indirectly through AOS font engine.

Why?

Yes: libfreetype + fontconfig + HarfBuzz + Cairo. That is the WebKit 2.50 text stack (same family as WebKitGTK), not a random extra.

Your OWB diskfont path was the right call for that engine. Quasar is not that WebKit. Layout, CSS, @font-face, WOFF/OTF, and complex scripts all go through FontPlatformData/FreeType and HarfBuzz. Page text is UTF-16 inside the engine; glyphs come from the TTF Unicode cmap. AmigaOS codesets / diskfont.library cannot be that backend without rewriting the font cache, glyph pages, and shaper.

Speed: diskfont can beat FreeType on a handful of Latin UI glyphs. A modern page is not that. Glyphs are cached; the cost is layout and script, not Bullet vs FT per letter. We still ship PROGDIR:Fonts/WkSans.ttf so it runs without a tuned SYS:Fonts set. fontconfig can index extra TTFs under PROGDIR (and SYS:Fonts when they are real TTF), it does not draw through diskfont.

So: native OS4 fonts stay a possible fallback for chrome later. They are not a drop-in replacement for the 2.50 web text path. I did look at the old OWB sources — different problem.

If I could wish for one game on AmigaOS 4.1, it would be Wing Commander Saga: The Darkest Dawn.

It is a finished Wing Commander story, and it already runs on the open-source FreeSpace Open engine. That engine is cross-platform C++ and uses the usual pieces AmigaOS 4.1 already has: SDL, OpenGL, and OpenAL. So this is a port of an existing engine, not a rewrite of the game. I would love to see it fly on AmigaOS 4.1.

@joerg

I'm using (new) sii3132sata.device from Acube (https://www.acube-systems.biz/download ... =sii3132sata_dev_v1.2.lha) when using with CDFS v53.11 I get in BURN IMAGE "CD0: HL-DF-ST DVDRAM...." in Drive chooser and can burn CD/DVD.

But when using ODFileSystem (or beta CDFS v55) in Drive chooser I have a blank entry and can't burn CD/DVD.

So seems AmiDVD uses CDFS for something.

Does AmiDVD has some debug option?

For "resource" I mean CDFilesystem kicklayout/handler.

With ODFileSystem from os4depot/github and in BURN IMAGE I get an empty "Drive" chooser, so don't know how you get/fill that list, but with ODFilesystem (works fine under OS4, can read many CD/DVD formats) it doesn't show any "CDx: blah blah" entry on "Drive" chooser.

I never used ODFileSystemm, but AmiDVD may depend on the CD/DVD/BlueRay file system using DOSType "CD01" (shortcut for "CD001", which is the official ISO 9660 FS identifier, but AmigaOS DOSTypes are limited to 32 bits, 4 chars).
All AmigaOS CDFileSystems I know of, the commodore CDTV/CD³² based ones, as well as any 3rd party ones like CacheCDFS (incl. the AmigaOS 3.9 version), AmiCDROM, AmiCDFS, AsimCDFS, BabelCDFS, etc., are IIRC all using the same DOSType "CD01".

If it's not related to that:
Which PATA/SATA/SCSI/etc. device driver are you using? An incompletely implemented one could cause problems as well.
I only tested, or had beta testers testing it for me, AmiDVD with sg2's PATA/SATA/SCSI drivers (a1ide.device, peg2ide.device, sii0680ide.device, sii3112ide.device, sii3114ide.device, sii3512ide.device, lsi53c8xx.device, etc.) and Ignatio's NetBSD based SCSI driver (cbyppc.device).

Yeah, fonts on your old Origyn Web Browser had also a nicer look, where we can found the source?

All of my AmigaOS 4.x parts were on the Pleyo OWB SVN.
That doesn't exist since several years anymore, but the author of the AROS OWB port who, unlike the MorphOS OWB developer, uploaded all of his changes to the Pleyo SVN as well may still have a copy of those sources.
I don't have the complete OWB sources anymore, all I have on backups are diffs of my latest changes to the OWN SVN, and the sources of my AmigaOS 3.9/m68k port which doesn't include the AmigaOS 4.x-only AmigaOS native font rendering functions: The bullet.library from AGFA Compugraphic used in AmigaOS 2.1-3.9 was way too limited compared to Detlef's AmigaOS 4.x outline font engine.
