I have some problems with running the Batman Vuelve demo in WinUAE. Here are my findings with the QS 1.3 ECS 1MB Kick config:
with version up to 1.0.0: graphics error with the first dot circle tunnel as in picture 1, does not continue there
version 1.1.0 and 1.1.1 : shows the dot circle and pentagram tunnels 3 times each correctly, but has a graphics error in the tunnel afterwards (see pic 2) and does not continue
version 1.2.0 and later: draws the dot circle and pentagram tunnels 2 times correctly, at the third dot circle tunnel graphics error as in pic 1 and does not continue
with cycle-exact option off: shows tunnels correctly but crashes at the cube with the panther (pic 3)
with immediate Blitter: demo runs completely, but does not show the fractal tunnel
