Summary0003498: Trashed tree in parallax scrolling
DescriptionI've noticed (many years ago) the parallax tree sprite looks trashed in the original version of this game... (attached sshot).
Would be possible to fix it once and for all or is it too complicated?
TagsNo tags attached.

Looks like a chipset related issue.
Here Toni stated the problem disappears setting OCS chipset emulation on WinUAE:

EDIT: tested myself and confirmed.

i have this very same problem on real hardware. Maybe JOTD can have a look at this?

errr, that's really too minor to bother about that

Just wanted to say Codetapper probably found also the exact reason behind the bug...

Maybe you can collaborate to fix once and for all this Amiga classic.
Still hoping for a fix, maybe one day... ;)

...in the meanwhile with WinUAE I've found is possible to fix also that glitch using these tooltypes for the WHDLoad slave:

ExecuteStartup=
ExecutePostDisk=UAE-configuration cachesize 0 cycle_exact true cpu_multiplier 4 chipset ecs_denise

chipset ecs_denise did the trick!

Is it possible to force "chipset ECS" mode in the slave? This will automagically solve also the tree sprite issue in the main menu.

ECS Denise mode to be exact (with WinUAE this removes the sprite bug)
