Hi everyone and sorry for my english

I downloaded o2em v. 1.20 beta from the link I found on your forum site - "Christmas 2011's gift"

- for Windows 10 and I got roms.
It is fantastic.
I've problems only with Norseman, that is my favourite game and the reason why I looked for Videopac emulator.
The problem is that the man doesn't move correctly: it is really slow when I move right and if I move with "the gold", he doesn't move at all on right direction. IT works only on the left, up and down.
The problem is the same with keyboard keys or with a joystick.
All the other games I tried (Pickaxe Pete, Superbee and Turtles) work perfectly on every direction.
I tried to read your forum, I tried to read manuals too, but I found nothing about a problem with this game; and if there's something I have to do that's written in the manual, I admitt that it's a little too technical for me

Can anyone help me, telling me what I have to do to?
Thanks and sorry again.
Laura
