There is no "push pc". The "call $+3 \ pop hl" will work, though. (But just to reiterate, it's not relocatable, which probably isn't a problem for you.)

I had thought so, I just couldn't quite remember.

What I want to know is how hard is it to work with the screen now? Displaying to the screen etc on the 83+/84+/SE was a PITA. Most programs were slowed down due to displaying to the screen and not due to their engine being slow.
In TBP I decided to skip 4 frames in order to get a good speed out of my game. So "physics" is perfomed 4 times before the screen is updated.

So, how big is the screen buffer going to have to be now? How long will it take to update the screen. How hard is accessing the screen memory going to be? All questions I want answered

If I remember correctly you could do a push pc \ pop hl to store it in hl. You wouldn't want to leave it on the stack because on the next ret it would jump back to it.
If that doesn't work a little hack you could probably do would be   call self
self:
  pop hl

The incident he was talking about was something that happened last year. The SirCmpwn incident. So it happened a lot more recently then everything else mentioned ;P
We both are right, I'm just assuming you thought I was talking about something else.

From what I understand, the campaign is harder because you run out of ammo a lot faster.
