So patience is a virtue.Įnough pieces of software are working for it not to be a waste of time but not everything works yet. Tapes load without making a noise at their original speed. Click on the emulation window to bring it to the front. The options menu is presented in such a way as initially to have keyboard focus. Which might be just too many things to happen in the same cycle? I've also yet to implement latching or the shift register or figure out why my emulation of the IRQ Tester mentioned above fails when trying to test IRQs. I've yet to fix the 6522 off-by-one issue, but my guess is just that it's just because when you programmatically seed the timer I also tick it down that same cycle.

As I've not yet implemented an automatic typing of appropriate loading commands, you'll be free to use BASIC instead if you prefer. It being document oriented is possibly a curse as much as a blessing: you cannot get to an Oric without supplying a. TAP but that might help to confirm or deny. I haven't yet found a speech demo that was just on a. I don't think it's quite as cycle perfect as I'd intended yet. But really I just need to work harder.Īudio sometimes drops out and never returns.

The flattering version is that it's because I've preferred a clean structure and because I've got a full CRT emulation running (though you can't tell yet, because I've not implemented 60Hz output, so no fun image rolling when the resolutely 50Hz CRT loses synchronisation). On my development machine - the 2011 11" MacBook Air - it takes about 30% of a core to run. With a million issues, at least half a million of which I'm aware of.ĬPU usage is far too high for an emulator. I probably also need to improve my French being able to say thank you and ask where the train station is doesn't seem sufficient.Ī very early build.

I had a shot at implementing just the tone part of the AY but didn't succeed. Given that my laptop has an 11" screen, it's quite helpful. I also added in the necessary hint about which display lines are in use to give my emulator a direct crop on the pixel part of the display. Stormlord ended up at no behaviour, with a screen full of garbage, so I assume that loading failed and that it is so squeezed for RAM that it had also overwritten the display buffer. Everything's loading at genuine Oric speed so testing is a bit of a slog, but at least the titles below all loaded (all shown in composite-o-vision). I've made an attempt to support multiple-file TAPs so hopefully I've just made an error in determining file length or something silly like that. It's now working for some tapes but not for others.

interrupt fires 1.5 cycles after 0) but we'll see. I've implemented what I understand to be the proper behaviour (i.e. That's surely going to be the first thing I run when I get loading properly figured out.

Regarding timers, I wrote some benchmarking code few years ago which allowed us to notice discrepancies between real Orics, Oricutron and Euphoric, so when you have something that can run code, we should be able to help with your timings. There's also an RGB mode because the real machine also has an RGB mode. Also I've used a vanilla RGB to PAL encoder, paying no attention to the machine specifics so might be way off. That's not true of every machine, so might not be true of the Oric, I've yet to find out so just did the most PAL-conformant thing.

I've assumed colour phase advances by a quarter of a cycle on every line, hence the diagonals. Screenshots are all of composite video output. when it'll load things and produce the intended audio.

Will provide binaries when there's even the slightest chance of it being interesting to anybody, i.e. The timers are definitely cycle correct, but everything else is negligible. Also the 6522 emulation is probably terrible. it's just a shame that you currently can't load a single piece of software and the audio being produced is the silent wave, regardless of what you write to the PSG. Think like pointing a 60fps camera at your display, even if it's 50Hz phosphor decay and a genuine 60 different frames per second if your computer is 60Hz 144 different frames if your computer is 144Hz, etc.
