Re: Do I need to learn assembly to make a music disk?

Lots of music disks have been made with GFA and some small inline assembler.
I did one years ago: https://demozoo.org/productions/73565/


It is entirely possible with C aswell.

Re: Processor comparisons

As I deal daily on my job with Cortex-M core devices, it is a pleasure to get the constant positive reminder of the Archie :)

Talking about lowlevel assembler and what the IAR compiler produces, I can only tell that I would be unable to produce that tight assembly code myself.

No horizontal blank interrupt? And I remember so many great demos on the A3000 with raster bars.....Brothers In Arm come to mind *oh the memories* :) Back to the Archie, I think it could have been Armaxess as well.

Re: Inquiry about 'generated sprites' techniques used on the ST and the Falcon

Chunky or not, sprite data can be pregenerated for bitplanes as well. We call this technique "preshift".
Combining preshift with creating a direct algorithmn to apply the preshifted data should be possible aswell. I also think that's the way the real-big-sprite demos on the ST do work....

Re: Ataribox

Yeah, Zotac style is great. I own a Dell Alienware Alpha with Win 8 and for my uses, it is great as a Steambox. But this is also a reason not to buy the Ataribox for me, even if it is a Steambox. The Alienware does all Atari stuff via emulation and PC stuff via Steam. And it has a mobile NVIDIA chip...

Re: gcc 7.1 for the ST series

Statically linked binaries for 64 and 32bit to be placed into /opt would be ok for me. As long as it does not want obscure dynamically linked libraries, I personally will not need fully fledged packaging although it is nice to have. Maybe you can team up with Vincent Riviere?

Re: LPT to USB printer adapter

My good old Laserjet 1200 directly works on my Falcon through classic LPT connection. I only have to use a PCL-5 driver from NVDI.

As long your LaserJet still supports PCL, it should work. Maybe the port is lacking?
A flexible gateway solution would be great ofcourse.

Optimized 16 color palette

Thanks to Bonus, over at FB, the following post came to my attention.

I think this is a very interesting concept and I'm looking forward to see Atari ST graphics man to try this out.

Windows build with SDL2 support?

Where can I find an up-to-date build of Hatari for Windows with SDL2 support? The official release only seems to provide SDL1 as the controls in the GUI are missing.

Re: converting a SNDH into a VGM sound file

.YM file format samples direct register dumps of the YM2149 registers (16). IIRC a register dump for every 50hz tick is stored. As sample playback requires much faster rates, so any digi samples on a STF cannot be captured this way. OTOH replay is easy, "every 50hz copy register content to chip...

Re: converting a SNDH into a VGM sound file

It's probably impossible for generic SNDH as each SNDH file contains a driver written in m68k to program the YM2149 chip through interrupts. They do not contain simple register data to play back.

Maybe .ym files can be converted.

This is probably a case of the faulty DMA access. Try the devices on different ST machines, STF preferrable.
