This bootblock intro https://www.pouet.net/prod.php?which=71703 isn't displayed correctly in vAmiga. The small booze logo shows up (it's a sprite) but the twist effect isn't there.
It should be noted that this product as set as "AGA" on pouet, but it doesn't require AGA, but it needs a 020 CPU so that might be whats causing the issue here, that said the thing is running and the CPU is executing code, but something is going wrong somewhere.
Just tried the demo. In vAmiga 2.4 (Kick 3.1 + 68020), it started like this:
The background image was slowly drawn, line by line. After a while, when all lines were drawn, it started twisting:
I've also tried in FS-UAE. With the A3000 config, the demo worked as I think it is intended to work: It started twisting immediately (no slow line drawing at the beginning). However, selecting the A500 config and enabling a 68EC20 CPU manually, it looked like this:
The demo seems to be very sensitive to either the HW specs, or the Kickstart version, or both. Needs more investigation.
I think the slow line drawing at the start can be as designed if the CPU is "too slow", but I'm unsure.
