Re: Port Crazee Rider?

If you upload oricutron videos direct to YouTube, they often turn into an overcompressed mess, although it seems to depend slightly on the device you use to play it back. There is a thread on here describing how to pass the video through ffmpeg first for better results.

Re: Port Crazee Rider?

Looks really nice 👍. I wish you had put the vid through ffmpeg before uploading, though.

Re: Re-encoding Oricutron captures for Youtube

Just a quick additional note, if you change the "scale=720:672:flags=neighbor" parameter to "scale=960:672:flags=neighbor", you'll also give the video a bit of a horizontal stretch and make it look closer to the aspect ratio of a real Oric:

Re-encoding Oricutron captures for Youtube

Several people have found that if you upload Oricutron video captures direct to youtube, it re-encodes them into a crappy mess, even though the original video was losslessly encoded (and thus pixel perfect). The issue is that the videos are low resolution (240x224), so youtube encodes them with low ...

Our, to avoid fisheye, you just add a constant to all your distances, iirc. Simples.

Re: "music" in Xenon meteors noise

Oricutron also has accurate AY noise (or should ;-) )

Wow, iss! Nice work! Glad someone has time to work on Oricutron while I'm too busy :-)

Re: New tape fileformat (.ort)

No, it doesn't need to encode that.

Normal Oric data is stored in decoded bytes (same as .tap), so the fast/slow encoding has been stripped off. You could re-encode it as fast or slow if you like.

Other data is encoded as a waveform, so again no "fast" or "slow" really applies to the format.

Re: Oricutron 1.0 (EDIT: Now 1.2)

That mean that Dos-8D will never work if someone replace the 6502 with a CMOS version, clever! Depends on the instructions used. Some are the same on 65c02. The Apple II users learn that the hard way when Apple switched (and some user too) from the NMOS 6502 to the CMOS 65C02 version. But the Oric ...

Re: Oricutron 1.0 (EDIT: Now 1.2)

I don't entirely agree.

I think the current compile-time option should be made a configuration option. Oricutron is attempting to emulate a real piece of hardware, including quirks.

A better solution than not emulating illegal opcodes would be adding options to select 6502, 65c02 or 65816 emulation.

Re: Oricutron 1.0 (EDIT: Now 1.2)

Hmmm... according to the documents I could find online, opcode 04 is essentially a "nop", but it should consume an immediate operand. Looking at the code, I made it count the cycles correctly, but not consume the operand. No need for a message box. If you make all the "DOP" instructions add 1 to PC,...

Whoops! Thanks for the heads-up. I merged the fix from Godzil.
