Re: Clock Signal — an Oric emulator for macOS and Linux
Minor one: I may have bitten off more than I can chew with regards to my ongoing efforts to add the Apple IIgs to the emulator; it's just not that well documented, and I don't have a real machine. So that effort is obstructing progress elsewhere. With one minor caveat, which is that the SDL build of...

Re: Clock Signal — an Oric emulator for macOS and Linux
I don't know how pro-level I feel about the internals as I spend yet another day trying to conquer a relatively simple problem to do with the way the Apple IIgs does sort-of-NTSC-to-RGB conversion. Not to mention the continued lack of some relatively simple classic emulator functionality — save stat...

Re: Clock Signal — an Oric emulator for macOS and Linux
Super minor addendum: The Mac version had some UI issues under Big Sur; these have been fixed. It's also now available as an Intel + Apple Silicon universal binary. Slightly more technical discussion starts here: Re: Big Sur, I'd unwittingly made a dodgy assumption with regard to the means by which ...

Re: 65c816 and twilighte board/orix : here we go :)
I'm getting quite far ahead of myself here, but I'm currently working on the 65816 in Clock Signal, which means it'd be essentially trivial to add support for at least an 65802 to the Oric. So if there is any extant code, it'd be great to know more about it. Though a full-on Twilighte board might be...

Re: Image mapping : Peer review needed
No, it's not perspective correct — it's an affine rendering. So exactly what you'd see on an original Playstation. As per discussion above, the problem is that texture (x, y) aren't linear in screen space; (x/z, y/z, 1/z) are but then you need at least one divide per pixel to get back to regular (x,...

Re: Image mapping : Peer review needed
It's more or less what I'm doing in the rotozoom code in my demos :) - add offset_x/y to move along one axis - add offset_y/x to move along the other axis Yes! It should be exactly the same thing for a PS1-style linear mapping. And, of course, Wolfenstein, Doom et al are always linear per pixel; th...

Re: Image mapping : Peer review needed
I can't speak closely as to the original sources, but the classic serial implementation for affine texturing a polygon is just two adds per pixel. In pseudo-C: for(x = start ... end) { pixel[x][y] = pixel[texture_x][texture_y]; texture_x += offset_x; texture_y += offset_y; } ... with appropriate mod...

Re: Clock Signal — an Oric emulator for macOS and Linux
A minor one to announce: the macOS version of Clock Signal now uses Apple Metal for video output rather than OpenGL. That's because Apple has deprecated OpenGL and therefore at some point it will become available. Apple has announced that it'll still initially be available on Apple Silicon Macs but ...

Re: Clock Signal — an Oric emulator for macOS and Linux
This I was unaware of; I'll stick my nose in tonight. Also, for the record, I switched my desktop to German (the only other language I can read any of) and had no problem running the emulator; I'll keep digging. Other than the ongoing Qt stuff — I'm currently engaged in the Qt forums re: the audio i...

Re: Clock Signal — an Oric emulator for macOS and Linux
Thanks for giving it a second chance! Now you mention it, I've had no audio from the emulator in a couple of my Linux virtual machines but I didn't think much of it since virtual machines often have issues like that. But I should check. No doubt there's some sort of error in there. To clarify on the...

Re: Clock Signal — an Oric emulator for macOS and Linux
Update on this! I'm confident I've fixed the reported crash and the route to a window crammed with all the interface elements at once. It is also likely that I've fixed the failure to display a screen. So please once again refresh your snap — either via the command line or through the Ubuntu Softwar...

Re: Clock Signal — an Oric emulator for macOS and Linux
I had installed Clock Signal with Ubuntu Software utility. Then I uninstalled it and reinstalled it though snap utility. If it helps at all, Ubuntu Software and direct snap installs are identical — the former uses the latter underneath. But the two distributions I tested with access to the Snap sto...

Re: Clock Signal — an Oric emulator for macOS and Linux
@ jbperin : Attached are all Oric related ROM files for Clock Signal (together with a txt file which explains 'who's'who') ;). Thank you Iss .. Unfortunately, it doesn't prevent ClockSignal from crashing when I drag'n'drop the rom .. I don't know if there's a way to provide Clock Signal with these ...

Re: Clock Signal — an Oric emulator for macOS and Linux
Quick update on this: I think I've cracked the Snapcraft code, so if you use snapd then you should now be able to install a prebuilt Qt version of the emulator. See its listing here . Or, if you're a Ubuntu user then the following may work: open 'Ubuntu Software'; search for 'Clock Signal'; hit 'ins...

Re: Source code repository discussion
I guess github does not support Windows targets, or is it just that you never configured it for your emulator? I haven't run Windows at home for 17 years, or as any part of my job for 12; I've used Windows 8 or 10 exactly zero times in my life. The limiting factor is me. Conversely, I had a Windows...
