Re: Frame pacing

Jon - I've uploaded lcdgm with VSync fix to the dev area (LCDgmVS022.zip). Take a look at the source to see how I did it - was quit simple really. Quick question - when you say "the next (Pi) beta" are the betas computer specific? I've downloaded v2.34b and transferred to the A4000 so I ca...

Re: Frame pacing

I dabbled in this with LCDgamemodes (do you have the test version which reduces VSync?). I've not seen that version - not that I recall anyhow. That last version you put on the dev site is 0.21b, from which I based 0.22d to botch VIDC20 support. Ok, I've located this today. It was v0.22, hidden awa...

Re: ADFFS 2.34 beta

Today's Pi RISC OS beta ( 31-01-14 ) finally resolves the sound randomly cutting out . I've not had a chance to personally check, but have had a few eMail today confirming it has definitely fixed the problem. A big thanks to Jeffrey Lee for tracking that bug down. That *is* great news! :D I'll be c...

Re: Frame pacing

HI Jon, this makes interesting reading. I dabbled in this with LCDgamemodes (do you have the test version which reduces VSync?). I tried a couple of methods, from memory: 1) trapping the VSync at the IOC interrupt trigger, before RISC OS issues vysnc event (4), and only allowing through 50 vsync eve...

Re: ADFFS 2.34 beta

Nice work Jon.

Have downloaded onto my Pi. Will test properly at the weekend.

As there seems to be a need to ensure certain version of RO is present on the pi, would it be best to report an error on loading (on Pi), if an incorrect/old version of RO rom is present?

Re: TrackerModule

Should we need to do this for another tracker module, its coded as follows: When we configure the sample rate, work out the ratio of the sample rate we want to the one we got: If a linear handler is installed: R=((W/(G/1024)))/1024 otherwise, must be logarithmic: R=((W/(G/1024))^2)/1024 In the buff...

Re: QTM v1.44 development version

The TXP format is one which I originally described to Andre, on the basis that it was so similar to existing formats that I might be able to get him to add native support for it in lieu of having to write a converter of some kind. Ahh... ok, I'm guessing nothing ever became of their tracker/player ...

Re: Vinit, Vstart, Vend

Steve, am I correct in thinking that Vinit is used as the start address of the frame, which stops at Vend or VDER, whichever comes first. Where does Vstart come into it? The VLSI manual doesn't make that clear. I'm using your Hscroll code to get it working on both IOMD and the Pi, as I've yet to fi...

Re: QTM v1.44 development version

I tested with QTM1.43 and 1.44 beta on the Pi and 3.71 emulation. Just silence when playing them, even tried manually loading them via. MusLoad / MusOn. I'll test with QTM1.45, although the issue could be in Mus2QTM if they're playing for you. Sound effects we're working okay, although I'm not sure...
