Rybags Posted September 7, 2021 Share Posted September 7, 2021 That image would be using sprites in the border. Though I think some other trickery is going on as well. With unexpanded multicolour sprites you can only cover 96 of a possible 160 pixels horizontally. I suspect that some of the sprites would be 2x expanded single colour which could make up the shortfall. Quote Link to comment Share on other sites More sharing options...

The youtube video capture of the source demo shows a static image with 8 scanlines missing from the top & 13 from the bottom, i.e. 272 visible.

Yeah, but the question was not so much how does the C64 put graphics in the upper & lower borders, but how does it hope to display borders beyond the PAL specification of 288 vertical (non-interlaced) scanlines maximum? On some sort of monitor output? I know very little about the C64... Quote Link to comment Share on other sites More sharing options...
Rybags Posted September 7, 2021 Share Posted September 7, 2021 (edited) Like I posted, it's a music piece with static picture. It's using sprites in the border which allows more than the C64 stock 200 scanline limit of displayed graphics thought the bulk of what can be shown outside is sprites. I'm not sure what the upper limit is. The default Atari situation is 240 scanlines but we can use the hires as last displayed/scanline 240 bug to allow displaying PMG objects in the remaining scanlines. I would guess the C64 probably allows using close to all the possible 312 scanlines. The 288 scanline thing (or 240 with NTSC) - that's just a specification that assumes a "TV safe" area where you're fairly guaranteed most of it will show. It's entirely possible to generate a PAL or NTSC analog display that uses all except the few scanlines that are required for VSync. ed - as for the picture that's showing 293 or whatever scanlines - I'd say quite obviously it's and emulator screenshot. But that said, entirely possible a TV could produce the same. Edited September 7, 2021 by Rybags Quote Link to comment Share on other sites More sharing options...

It's entirely possible to generate a PAL or NTSC analog display that uses all except the few scanlines that are required for VSync. According to this, 288 IS the supposed maximum, having deducted the minimum 25 scanlines required for VSYNC in the PAL specification. This supposed upper limit is therefore not to do with 'TV safe' overscan, which is a different issue and usually considered to be well below 288 displayed lines for PAL. Websites discussing the C64 overscan area appear to suggest that the VIC II generates 284 scanlines between VSYNC periods. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted September 7, 2021 Share Posted September 7, 2021 (edited) doesn't matter I can't run it on my C64 or 128... seems like it wants 2 more sid chips and doesn't wan't to display properly on NTSC?? Can anyone confirm? It doesn't look nearly like what is shown here nor does it play right... I guess I need to install extra SID chips or? Maybe 3 machines? haven't dug to deep or read much about it, just thought I'd grab it and be good to go, silly me... Oh, well... wasted enough time on this... time to see some more rasta(s) Edited September 7, 2021 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
Rybags Posted September 8, 2021 Share Posted September 8, 2021 I can only do an NTSC C64 in emulation. In either system on 1 SID it's just playing 1 note and seems stuck. On NTSC the screen is distorted. Fair chance it might be PAL only. There'd be a degree of CPU usage offscreen. In theory the tracker stuff should be able to run in the display area, but from what I've seen by running it, yet another program that doesn't care for NTSC.

_The Doctor__ Posted September 11, 2021 Share Posted September 11, 2021 I still think we should have built the towers back in the exact same dimensions as well as look, just made them tougher and 7 feet taller. I am a firm believer in showing those that want to do harm that there is no gain in their actions... at least we all came together to help, clean up, and fight back. To much division to even consider under the current goings on. 3 Quote Link to comment Share on other sites More sharing options...
Sheddy Posted September 11, 2021 Share Posted September 11, 2021 (edited) On 9/2/2021 at 4:38 PM, drpeter said: A further manifestation of RastaConverter's player repositioning bug I've recently stumbled across another consequence of the player repositioning bug in RastaConverter- one that seems to occur less commonly, but also is obvious when you think about it. It's the reverse of the usual situation, the one where RastaConverter assumes a repositioned player will be displayed in its new position on the same line but actually it is not- allowing pixels from COLBAK or a player with lower priority to unintentionally 'show through' instead. This 'new' type of error can occur when RastaConverter repositions a player after it has already triggered but not yet displayed at its current HPOS (i.e. during the 5-6 colour-clock delay between these 2 events). RastaConverter is not aware the player has already triggered, and that it will now therefore be displayed at its existing 'old' HPOS position regardless. It assumes that the repositioned player will NOT be displayed at its 'old' HPOS, thereby allowing COLBAK or lower priority players to appear, but in fact any such pixels end up obscured by the player displaying at its 'old' position regardless of the repositioning. @Sheddy will be including this new observation in the annotations of disassembled Rastaconverter .xex files output by Rastaslide (output.png.rp).
