Is Amiga Emulation better than the real thing?

@Amigaski

I am currently trying to port my game from real Amigas over to WinUAE/UAE/etc.

One of the things I do is like this:

Code: [Select]


IF (UAE) THEN
  // don't bother reading VPOSR on WinUAE. No point.
ELSE
  // take VPOSR into account when drawing realtime gfx
END_IF

Am I doing the correct thing?

I claim that it's possible to emulate an Amiga or a A800 percectly accurate

Of course it is possible.  Just because it has never actually happened does not mean that it is not possible.

I claim that it is possible to move from point A to point B at 256x the speed of light.  Just because it has never actually happened does not mean that it is not possible.

I suggest you throw away all your amiga games as they all use double buffering... Have you ever writen a game on an Amiga?

I have, and so have some of my friends.  None of them use double-buffering.  AFAICT double-buffering is only really useful when displaying an FMV movie.  It is often a mistake to double-buffer a whole game on the Amiga.  The Amiga has real-time beam position knowledge with approximately 1/21000000th second resolution (if you want the exact number then consult your HRM).

Yes I was thinking of 2D games.  Most Amiga games are 2D.

I would assume that most 3D games and some 2D games use double buffering.

no double buffering will look like crap... All blitter ops will look nasty

Wrong.  It all depends on what you are blitting and if you are making use of the Amiga chipset's awesome features (Jay Miner rulez 4eva) and how you have written your code.  Some games require double-buffering and some do not.

Sorry bloodline, I hate to use the phrase "you're wrong", but you really are... The weakest Amiga I own is able to push a lot more than 2 megabytes per second.
