Elite rendering issues

[wiebel]

This is probably already known, but just in case. Elite's background bitmaps are rendered at an offset of around half a screenheight. I t would be great to be able to play Elite in one of it's original forms.
There is probably an mid screen mode switch involved.
As it's one of the best documented game codes this might be helpful:

I'll take a look.

AFAIK Elite is PAL and NESTang is NTSC, so that's why it renders like that. Eg: Mr Gimmmick PAL running on NTSC.

Idea: Maybe adding a PAL/NTSC option in Options that changes the CPU clock might fix it? PAL runs at ~1,66[MHz) while NTSC runs at ~1,79[MHz]

As I thought, changing system_type to PAL fixes the issue

Edit: This fix is not in any official PR yet, so won't be part of any official release soon
