hello,
i just observed strange thing: when i change (under vbl) address of videoram in hicolour mode (falcon ofcourse) with the values multiple of 2 (vram+2, vram+4, ...) i see some screen errors on the left border (by scrolling; by static picture i see sometimes also some errors but i'm not able to describe it - all in all it's not such crucial). but when i change scroll values by multiple of 4, everything works as expected.
could someone explain why falcon hicolour behaves like this? it should work for 2 bytes boundaries, too or not? i tested in on vga/100 hz only.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
