Want to see something odd?
No? Well, I'm going to post it anyway. Here's something that fails differently on the MiSTery core as compared to both Hatari and STeem SSE.
On PoV 16, and it appears to be a Version 3 which I've attached to this post to ensure we're all looking at the same disk, the S.U.C.C.E.S.S. demo.
For reference, here's how it's supposed to look. This is on the MiSTery core using the ST chipset and running TOS 1.4. The results are the same with TOS 1.2 which I also tested.
Now, here's how it looks using the STe chipset and running TOS 1.62.
Looks like the palette changes just aren't happening as the scanline moves down the screen. Interestingly, this effect also seems present as the demo unpacks itself. With the ST chipset you see the coloured lines characteristic of a demo unpacking. With the STe chipset, the screen just pulses different solid colours with no changes mid-frame.
Running under both Hatari and Steem SSE presents the same result on an ST with TOS 1.02/1.4. The demo works.
The demo also fails to work properly when the emulator as configured as an STe with TOS 1.62. However, it fails in a different way. The depack routine looks normal with actual coloured bars, and the demo looks like this with the bottom of the scroller corrupted.
It doesn't look exactly
like that. The effect is only present once every three or four frames, creating some very annoying flicker.
So... which is correct? Perhaps someone with an actual STe up and running right now could confirm?
