Re: New SuperVidel & some ideas for future development.

Yes, that's why I explicitly said "when it comes to 3D rendering" :) What I meant is that if you have a 3D heavy game/demo, the biggest gain will come from skipping the C2P process + faster bus. As soon as you start using its enhanced resolutions, SuperVidel's advantages start disappearin...

Re: Hatari Video turorial?

Thanks for that. I haven't been able to get anything to work after following the instructions above and trying a few other things. I only ever get the generic green desktop screen when I fire up Hatari no matter what I seem to do. The game I've been using is Anarchy: http://www.atarimania.com/game-...

Re: Found some old pictures :-)

Funny, the (french) ST Magazine had put "Match It" on one of his cover disks, and it was actually a standalone edition of the demo version, as it has the Chambers of Shaolin Mad Max music. The font (Japfnt) is from Chambers of Shaolin as well (the nice intro with distorting credit pages)....

Re: Converting .TSD to another format

That's a software synthesizer exclusive to the Magic Synth tracker, so I'd say no.

Of course the SNDH versions can be played in more players but it's still TSD inside.

Re: Atari ST HDMI solution from The backofficeshow

Even if this thing does scandouble to 31 kHz, chances are slim that it will output 50 Hz motion. The cheap ones deinterlace the progressive signal from the ST by either skip one field or mix both fields, both resulting with 25 Hz motion. Useless for demos or games. The viable 50 Hz HDMI options are ...

Re: state of the art atari SNDH music?

Perhaps if I got time tonight I'll try find some 60+ Hz file that doesn't use all timers and setup a true interrupt and an approximated 200 Hz. It will be interesting to see if I can notice a difference :-) Ok, so I did a test between a true 70 Hz Timer A (ok, 69.8181 Hz) and a simulated 70 Hz from...

Re: state of the art atari SNDH music?

This is normal as many trackers use three timers for effects (A/B/D) and the remaining timer is C. Timer C is also used by the OS (plus harddisk driver) for it's 200 Hz clock. If you want to play the songs without killing the OS the normal thing is to hook on to the OS 200Hz Timer-C and call the mu...

Re: state of the art atari SNDH music?

Worst is the music driver tick system. Some musics are not exact 50Hz music. For instance some music are 52Hz. Instead of using a 52Hz timer, a fixed 200Hz timer is used, and time to time music driver is called or skipped. So the music tick is not called at 52hz exactly. But maybe original Maxymize...

Re: RGB to HDMI does this work with a ST

A way to test is running a program that alters between two colours every second frame. If it flickers like mad, it's good, if it doesn't, it's bad. So I made a quick one for testing: http://ae.dhs.nu/tmp/flicker.zip The screen will cycle between green and purple every second VBL. A converter that o...

Ah, now I see I should have been more specific - I'm talking purely about DMA playback, no disk access at all. So you're saying that as soon as you load your sample buffer during VBL, you don't have to care about anything else, you just let it play and do whatever you want in Timer B handlers? Late...

DHS fullscreen demos doesn't load while in hardsync, they refill buffers between screens.
