Summary06218: Hi. There is a strange bug in this game that only occurs on a Amiga 500 plus.
DescriptionGameVersion: PD version
SlaveVersion: 1.0 and 1.1

Hi.
There is a strange bug in this game that only occurs on a Amiga 500 plus. It happens everytime without exception with both the floppy disk PD version, and WHDload installed game.
The bug does not occur on a standard Amiga 500 and it doesn't occur on a Amiga 1200 either. It does happen with both a 68000 cpu and a 68010 cpu in the 500plus.
The issue happens no matter what ROM is used as far as I can tell.
On a Amiga500 plus, if you perform the move left, down, left, up in quick succession then it causes you to loose a life, even though you haven't hit yourself. The game freezes for a moment and you loose a life, but it does not show a collision. This happens if you use the keys or a joystick.

Hi.

I'll definitely give it a test when I get chance. It might take me a little time to get round to it though.

Hi. I've finally got round to it. No issue on the 500plus using that slave. Works perfectly.

Hi. Yes the issue does happen in the second slave, however only after carrots are eaten. If I'm careful to avoid the carrots then the issue doesn't happen.
Thanks

Hi Matthew,

Thanks for feedback. Its seems that my fixes were wrong. I cannot reproduce this issue, so I am affraid it will take some time. So I replaced slave with another one 1.1c internal. Please check and back to me with information. Thanks a lot.
