Re: Hatari 2.1.0 has been released

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.

Re: Hatari 2.1.0 has been released

Ok, I got the pattern now: * On TOS <= 2.x and >= 4MB of RAM, screen width needs to be 128 + multiply of 256 pixels, regardless of how many planes there are * With less RAM, TOS v3 or EmuTOS, it's enough for width to be multiply of 16 bytes (i.e. 128/planes) I've commited a fix for this and update t...

Re: Dune II / OpenDUNE for Falcon (and TT)

Tested the new version by playing through one level. It plays pretty nicely, the main problem is that keyboard input for scrolling is buffered. When things get slow, it's really annoying to wait game scroll past the area I wanted before it starts scrolling it back. -> Could how much game buffers key...

Re: retro-io Floppy Extractor Online

Re: Dune II / OpenDUNE for Falcon (and TT)

Btw. it's possible to automate profiling with Hatari so that it will automatically find for you a slowest frame in your game while you play, and provide profile for that. That was used in profiling BadMood, where it was especially useful because Doom supports gameplay record & replay. For OpenDu...

Re: Dune II / OpenDUNE for Falcon (and TT)

Thanks, it's getting more playable, or I'm getting more used to things getting slow when there are a lot of items moving on the map (with emulated Falcon). :-)

I guess I could try next profiling emulated TT a bit instead of Falcon.

Not sure whether everybody already knows this, but when investigating Videl register values, you can use Hatari debugger "info videl" command.

Hatari v2.1 is normally built with PortMidi support, with that Hatari can connect directly to ALSA MIDI devices like QSynth. Just remember to start QSynth before Hatari, or it's not visible in the Hatari GUI MIDI setup lists. Only older Hatari versions, and builds without PortMidi support require ra...

Re: Dune II / OpenDUNE for Falcon (and TT)

One of the things DML did with Bad Mood was converting the Doom data to be more optimal for how BM works. Same could also help Dune. Anything that requires run-time conversion, could be have an offline tool that converts the data to the optimal format, which would then be used at run-time. (In BM, t...

Re: Mouse buttons come and go

At some point mouse buttons wear out. Maybe that's the issue?

(That can cause weird issues, e.g. mouse buttons being pressed down too long, or generating extra clicks.)
