Wich one of these two Prince of Persia you prefer?

[emkay]

I would like to contribute somehow to a potential port... even with my not much skilled 6502 knowledge...

Well if you are up for it pm me, I started writing generic bitmap mode sprite routine. PMs will require little shifting around but all is doable...

 

Hm.....

 

I wonder if we have to empty the US main Cornstores. Waiting for a final Atari Prince of Persia could cause a shortage there. All that Popcorn for waiting ...

At least someone has intentions and guts to start...

 

Emkay I usually go out feeding some Animals near me including Piggeons.

Why don't you also go and use some of that Corn to feed the Piggeons. There are Piggeons everywhere!...

Why not eat the Pigeons? Eating takes longer and less birddo everywhere

[José Pereira]

Because I like animals.. in general.

 

And we can't eat anything that we don't like.

I prefer to eat what I like. Sad is that I can't do that very often

[José Pereira]

Lots of W.I.P. lately ...

Like, for example, this W.I.P.:

Also great because I finally get myself how to use GED's Mid-scanlines changes using G2F and could sucessfuly have that 'M' in a different luminance than the other text .

 

Now it's time to work on the Top & Bottom part...

Very difficult trying to mix Medium and Hi-resolution ...

will midline changes not screw up on NTSC?

[José Pereira]

Good question...

Probably someone here can give an answer to that...

(I only can check it on Emulator Atari800WinPlus and it works on both PAL and NTSC)

 

But the Mid-scanline changing it's just 'my like' of having that 'M' in a different luminance as even the 16bit versions have it the same colour as the text.

If no Mid-scanline changes:

If there are cycles for that it can be added later.

 

Now, only left to remake the bottom part.

Why should mid-line changes be messed up on NTSC? AFAIK the timing on a raster line is the same (almost) as PAL. PAL only has note of them.

[Rybags]

Mid-line stuff is exactly the same, only the C64 has 3 variations of cycles per scanline, which makes things hard - Atari is always 114 cycles and 262 or 312 scanlines.

???

 

I hope the border will get more unique? As you can double 3 players easily with midline changes.

And do underlays with missiles where the letters have to be highlighted, you still can keep charmode there.

As it is a still image, you can rebuild it 99% for the A8 ... just some different colours got to be used.

[Heaven/TQA]

yeah, was not sure regarding NTSC what G2F "overhead" is in the GED code... I thought you had less cycles in the "border"... nevermind.

[emkay]

You only have less cycles in the VBI

There is a VBI on NTSC machines?!?

Yeah, we discovered some, by accident.

Emkay by now I am porting that picture with some A8 possibilities... And by now I like the colours I have.

 

About Players re-use and Mid-scanlines change in G2F it's exactly like in 'Little Britain' on the Travel Agency:

"The computer says NO!"

 

No, because I need ANTIC4 on the Top and Bottom Multicolour and then I have two options:

-> Have GED with no BadLines that is all screen in Bitmap Mode

(In G2F I can't have some lines in Bitmap Mode to use GED and others in Char-Mode)

-> Use ANTIC4 and no GED possible because I need GED also on those BadLines.

 

By now the screen is all in CharMode.

Later, when it's finished I'll see if I get someone that change the Hi-Resolution in GR.0 to GR.8 Bitmap mode and add the PF2 Mid-scanline change to get the large 'M' a different luminance, and who knows what more will be possible...

Now I am facing the part that I don't like:

Have to 're-build' all those symbols at the bottom... And what a sh... as they are with lots of dithering and those C64 Pallete Brown and Pink it's making my Eyes

[Heaven/TQA]

isn't brown and pink arabic style?

[Rybags]

Tiles from those old times were earthy, subdued (unsaturated) colours, so probably yes.

 

The intro screens are probably best in bitmap anyhow - most of the data is text and it would probably use less memory to render it.

Advantage there would be that it could be done progressively, appearing over a second or so rather than just flashing up.

[José Pereira]

Simply and quicky, just save the C64 picture in '.bmp 16colours' format on PAINT:

 

Now I can see it better... I think... better see it later and take a break now

[emkay]

Look at this one:

 

 

 

Guess how many DLIs I have used there....

[José Pereira]

There you haven't used any DLI because:

-> Using PRIOR1 on Hi-Resolution (5th Player/4Missiles less priority than Players)

-> If that is a Light Brown ten you have (same as me) two Missiles quadruple width with 5th Player enabled gives you colour (Yellowish/Lighest Brown) and takes PF1 luminance (Dark Brown)

-> Large letters can then be Mid-scanline changes or two Players.

 

 

See there's no DLIs.

If it is not this then what I write now doesn't also have a single DLI.

And there are still two Players that can be used.

[emkay]

No DLI neither midlinechanges were used.

 

Is two players on both sides, Missiles do the highlight of the letters.

WRONG!

 

 

Oops, wrong.

-> The Missiles quadruple width are in the two large letters and there's still two Missiles to use.

-> The two Players taht gets the Yellowish/Lighest Brown are two players.

 

And there's still, the same, two players not used.

[José Pereira]

Was writing the second one when you were writing yours.

Of course it couldn't be Missiles expanded quadruple width because that way you couldn't have the Dark Blue PF1 inside.

 

Please consider this last one.

Everyone has a second chance, right ?

Almost

 

But, as you might see, it's an easy task to have the screen the right way.

Someone working on the main title?
