Demo "Dutch Breeze" consistently hangs at the same spot on U2+ (U64) #630
Description
The demo "Dutch Breeze" (CSDb Release #11584) exhibits an emulation error that consistently prevents full playback on Ultimate II+ devices.
Information regarding this issue can be found in the Lemon64 thread.https://www.lemon64.com/forum/viewtopic.php?t=88619&hilit=dutch+breeze
Steps to Reproduce:
Load the demo on an Ultimate II+ device.
Play through the initial sequences.
The demo always hangs directly before the cow animation.
Test Results (Real Hardware):
Hardware: Original Commodore 64 with a physical 1541-II disk drive.
C64 System: The hardware is equipped with a physical ROM selection switches.
Success Rate:
Standard DOS: 5 out of 5 attempts successful.
JiffyDOS: 4 out of 5 attempts successful. In the single failed attempt, the demo stopped at a different location (likely due to residual data in the 1541 RAM from a previous run).
Technical Notes:
The demo might have a bugged loader.
The test machine is equipped with a RAM VSP-Fix, which may contribute to the overall stability of the demo; no consistent issues were observed on this specific hardware.
On the U2+ device, the crash (freeze before the cow scene) occurs consistently at the exact same point every time.
Users on the Lemon64 forum have reported that the demo, surprisingly, works correctly when using 1571 emulation mode on the Ultimate device
