Graphic issue with Trolls_AGA and Start Problem with Trolls

[NoobieMaks]

1. Graphic issue with "Trolls_v1.2_AGA_0996.lha": All platforms disappear when the character is moved to the upper area of the levels!

This happens in my current build (buster + RePi 4.8.6 + Amiberry 5.6.8), in my older build (stretch + RePi 4.5.11 + Amiberry 3.0.11) this does not happen.

Start the game -> move into the first door (TOYLAND AREA 1) -> Jump on the first platform above you -> jump on the second platform -> jump on the airplane and time it clever so you can jump further to the third platform on the right (a lovely bear is sitting on it) -> and then only jump up and you will see that all platforms are disappearing when you entering a certain height, when you fall down on the platform everything comes back into the picture. -> This can be recreated in every other level too.

I found no setting in the GUI to fix it.

2. Searching for a working alternative for Trolls I ran into the start problem of "Trolls_v1.2":
   Amiga DOS Error: "Exception "Illegal Instruction" ($E010) at $23958E (Slave $16E) occured.
   In my older build I did not have this problem.

I found out when I create a config-file and set the CPU from 68000 to 68020 the game runs.
No graphic issue in this version.

The third alternative of Trolls ("Trolls_v1.3_CD32.lha") is running promptly and does also not have the graphic issue.

Regarding Trolls_v1.2_AGA_0996.lha, I can recreate the issue in both master and preview. The Preview version is in-sync with the latest WinUAE, so I suspect this is an upstream bug there as well, but I didn't have a chance to test it.

The issue with Trolls_v1.2 seems to be in the package itself: it requires an 020 CPU, when it shouldn't. This is fixable by changing the requirements in the XML of course - @HoraceAndTheSpider
