Sega Ferie with emulated inputs. This layout is based on Beena's, but I was able to get the pen cursor to move seamlessly between screen and panel element, no need to use a input button to switch between the two cursors.
No footage yet - running the ffmpeg export now - but the numbers themselves are beautiful.
Visible dropout statistics: Disc 1, Disc 2, Disc 3, Disc 4, Stacked. X axis is frame number, Y axis is max dropout length.
Same, but zoomed full-screen for Disc 2 in particular:
Same, but zoomed full-screen for the stack:
Some wins, some losses: - Loss: Disc 5 ended up having some player issues: The capture started having issues with the player abruptly stopping at around frame 32000 and then resuming. It was enough to make the capture unusable, so this is a stack of 4 discs instead of 5. - Neutral: All four discs had heavy amounts of dropouts, nearly every frame at lengths of anywhere from 200 to 350 samples (pixels) long. - Win: Despite not being a perfect capture, the stacked output is dropout-free for tens of frames at a stretch, and has a peak dropout length of around 65 samples, closer to 40 samples or shorter for the vast majority of the stack.
I'd estimate that a completely clean stack would need roughly twice as many discs. Fortunately, I seem to recall that all four of the discs were sourced specifically from one person - I'll sniff around and see if I can track down any additional captures to add into the mix later.
Thayer's Quest, arcade, 4-disc stack: Individual dropout graphs, dropout graph of stacked, and two additional graphs for good measure (showing that the blue spike moves with the player cursor, so it's not a dropout).
From four relatively mangled discs, to zero dropouts. NONE. A PERFECT FUCKING CAPTURE.
As Kale made this coinable when work was done on some other Taito drivers I decided to revisit the video.
It's not perfect (some sprite attributes such as the sizes, and possibly priority need further investigation) but it runs with proper colours now, and you can tell it is a game (see the cards etc.)
