Re: blit buffer to display, vro_cpyfm or vrt_cpyfm?

I suggest you pre-scale the fonts and scale graphics output while rendering. This will be much, much faster (and better looking) than scaling the finished bitmap. For monochrome mode, best looking output would probably come just by scaling height by 1/2 i.e. dropping every other row. I don't know h...

Re: Anyone to convert a Z80 music player?

I just managed to do some measurements using gwEm's CPU measurer (is that even a word? anyway). Hatari profiler can measure an exact amount of cycles for you, for any part of your code. Probably easiest way to do that is adding symbol for start and end of the part of code you want to measure before...

Re: blit buffer to display, vro_cpyfm or vrt_cpyfm?

No, unfortunately not. That would only work if VDI would also scale the source bitmap up/down while blitting, but it does not (NVDI can do that if you add 0x8000 to the writing mode, but other VDIs cannot handle that; also it might look rather ugly). Might look ugly? Monochrome scaling looks horrib...

If you use "--trace os_base" option, does Hatari output any messages about what might be going wrong?

Right... On further thinking I think it's best to forget that feature. While it could work for ST/STE, having it for those and not for Falcon/TT would be too inconsistent.

Re: NetHack Atari Port Being Depreciated

This would be very sad because Atari NetHack version was the very first one with a GUI, and its tile-set was actually adapted by upstream NetHack. Btw. Atari GUI was written by Warwick Allison (using his own C++ GEM toolkit), who's part of current NetHack DevTeam: https://nethackwiki.com/wiki/DevTea...

Currently window size isn't visible to Hatari, it's SDL internal thing. Hatari just sets internal framebuffer size and SDL2 scales that, to whatever size it deems suitable.

Probably the main gap in Videl emulation is that it gets palette only at VBL, so none of the raster effects works with it. There are also few other gaps which are mentioned in the compatibility.html and todo.txt docs.
