Prince of Persia

I don't know by now if it works, but think it could work:

 

 

See our Ship in A8 Warhawk. Different DLIs. gives different Blues in our Ship. The same PM, same xPos.

What change are the colour Register.

 

Of course it will not be that "Linish" but suppose:

Arms/Head/Up Body PMs -DLI- than the same PMs at the same xPos but one of them change from Skincolour to White Trouser's colour.

 

 

 

Effect of this?

"Our Kid's" only Hardware Sprite

Enemy must be Soft&Hardware Sprite

But the two never cchange xPos.

 

 

 

And now, if I can get this?

Better coding?

There's not really much difference between the 2. Like I say, there's no inherent problem with moving the Xpos of some PMGs, I'm just thinking about the poor coder who has to handle all these different methods to draw things.

If I understand the big problem would be:

In wich vertical Line you would change?

 

And of course it is the same, changing colour or changing xPos.

 

 

Probably is this, and Kernel/Raster/DLIs. problem on BadLines, yes or no prroblem?

 

 

 

And PeteD why you say Kernel was best than DLI?

What is the difference between the two?

(DLIs. is a specific Atari possibility with just corrrect nºs. to the correspondant registers, and others could bbe done on other computers).

 

 

By the way Kernel and Raster change are the same?

 

 

 

Thanks and greetings.

hmm, I never actually said a kernel was better than a DLI If you read what I posted I said.. (probably spread across various posts but I presumed it was obvious) IF the X pos moves are within Y character areas (or rather there's a character between them) you can trigger a DLI in it's normal place, change the xpos and then quit. If they aren't then you need something closer to a kernel where you'd trigger the DLI then wait for the correct Y position, change an xpos, maybe wait some more, change xpos. OR you could use a timer to trigger an interrupt at the correct line.

 

There shouldn't be a problem with badlines if there aren't many registers to change and if they're done in the right order.

 

As I KEEP saying, there's no inherent problems with any of the methods or multiple different ones, it's not a problem with the resulting code, it's the fact that some poor bastard has got to write it all in the first place..

Here is the Apple II version, along with a suitable emulator:

 

A2pop.zip

 

Just unzip it into a folder and run applewin.exe

click on the disk drive icons on the right to "insert" the PoP disk images..

Then click the apple logo, to boot..

 

default joystick emulation uses the numeric keypad, with numlock turned on..

Enjoy..

I messed around with some ideas for a title screen. It's not finished, and there are some parts that I want to redo:

Thumbs up for this excellent title screen!

Ok, so after some weeks of silence...

 

Here's my turn:

p_o_p.xex

Here's my turn:

 

Miker, that was brilliant!

[PeteD]

LMAO

Here's my turn:

 

Excellent !!

[Fres]

Ohhhh... Thas nice.

[w1k]

i cant run it on emulator :/ basic is off

[nosty]

buahahhaha AWESOME!

[TMR]

Y'know... i think i'd actually prefer if it that's how it was played! =-)

[miker]

So may it is broken?

Hahahahaha. Cool!

 

F.

[w1k]

very nice

[+JAC!]

cool, seems as if I was "Prince-rolled"

[w1k]

hello, whats new ?

[w1k]

something new in this project?

[Rybags]

To be a project to begin with, there'd have to be person/s working on it.

 

I doubt that's the case.

I read the original author found his source code. Maybe there's a chance he open sources it and the world can get at all the nifty, rotoscoped animation.

Cool - if it's complete and reasonably documented and he releases it, then it'd make porting a whole bunch easier.
