Re: idea. measure speed

If there's a demo sequence, it possible to use Hatari debugger & profiler to automatically identify slowest frame in the demo and automatically provide profile for it. It's quite convoluted to set up, but it was very handy with Falcon Bad Mood (especially as it could do that both for CPU and DSP...

Re: Hatari 1.8, Windows, how to change drive letter in file selector

Why not just register Hatari as handler for *.st files, or *.ST.gz files (latter to use less space and differentiate them from potential other files that might use *.st extension)? Then Hatari would be automatically started when you click on a *.st(.gz) file on your desktop.

Re: PLATOTERM - solving the screen redraw problem, need input.

You should use at least TOS v1.04. Nobody uses older TOS versions because they're so buggy, unless some specific game needs an obsolete TOS version (e.g. several games done with Omikron basic do funky stuff with ROM code and that part is naturally specific to ROM version which it was developed with,...

Re: App only draws under NVDI, wtf?

If you run it under Hatari, you can trace all OS calls separately, eg: "hatari --trace vdi,aes". On Linux, you can use Hatari (Python) GUI to toggle tracing options on the fly from a GUI dialog, on other platforms you need to drop into Hatari debugger to change trace options at run-time.

Yes, or some option that will allow it running with warnings and potential DSP lockups & rendering issues.

(Running it in Hatari, even partially, is IMHO much better than just looking at Youtube demo.)

Re: Bugziacs - "new" game released at Outline 2019

Just for the record, on the German ST Computer PD series, disk 66 iirc, there is a Maziacs for SM124 which looked great but it didn't have much sound. This looks nice. Shame that the Omikron Basic depends on poking TOS version specific parts in ROM, and works only with TOS v1.00 and from floppy. Is...

Re: EmuTOS 0.9.11

What if one would use fVDI for drawing, wouldn't EmuTOS then need "only" to support 16-bit resolution setting in XBios?

All DSP XBios functions (there are a *lot* of them) and related sound matrix changes would also be a large amount of work.

Re: HiDPI vs SDL aspect ratio?

I assume its SDL2 build. I would assume SDL2 to upscale from Hatari framebuffer with Atari resolution to display resolution, which should still be fairly OK with reasonable GFX card / GL(ES) driver. Problem could be that your desktop is doing compositing even for fullscreen windows, which can be a p...

Well the game Cometball runs well on Hatari (didn´t try the latest version,yet), but my PC is too slow, I think that causes the timing issues.

Hatari doesn't have any support for cursor control, and your issue might be a bug with SDL and/or your laptop driver. I remember there being some thread here about that.
