Re: Oricutron 1.0 (EDIT: Now 1.2)

Actually I need some help - I noticed in recent releases that Oricutron SDL-1x doesn't start when clicking on Oricutron.app icon but if I "Show Package Content" and click on the executable - it runs fine. With Oricucutron SDL-2x is exactly the opposite - it runs OK from Oricutron.app icon but not f...

Re: Hello from Bristol

What are your suggestions of nice pieces of Oric software to explore? Particularly interested in anything Oric-specific that is not as well known on other platforms. Don't Press the Letter Q! For which, thanks to the current slate of nutjobs, you'll get maybe a couple of relevant search results bef...

Re: Oricutron 1.0 (EDIT: Now 1.2)

I don't know whether you're building things automatically or manually, but I notice that the macOS build doesn't yet have native M1 (i.e. ARM) support. I have an M1 Mac, is there any assistance I can provide? SDL is now available for the M1, indeed I've already got the framework version installed an...

Re: Hello from Bristol

Hey Kon. You may be interested to know that a lot of the original work on Oricutron was done on a train from Weston-super-Mare to Bath, so basically in your neck of the woods :D It'd be interesting to know what proportion of Oricutron's functionality can be attributed to train delays... I think it ...

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...
