Mortal Kombat .scr overscan mode 0

[freemac]

Hi,

I'm trying to make a Mortal Kombat welcome screen between Lui Kang vs Sub Zero.

I'm using ConvImgCpc

What can I do better (I'm on layer &4000, &C000 being busy loading data and transfering them to RAM_4/RAM_5/RAM_6/RAM_7

[HAL6128]

I would prefer a Mode 1 with less colours and more (or less) dithering...

for the Logo you need some manual rework (right colouring)...

[robcfg]

Definitely the mode 1 screen looks better.


If you'd like to keep it mode 0, please choose a much better palette and avoid big areas of a single color.


Looking forward to see the end result!

Here's something in MODE 0... not as good as HAL6128's MODE 1 version, which is definitely the best so far!

[HAL6128]

...with Rhino's tool "Perfect Pix" you could create also a more enhanced Mode 1 Picture... .But then you will have a Overscan-Picture with 2 x 24kByte (Needs more RAM for interlace)

(and it flickers on the Screen, what you don't see here in the Image)

What is that "perfect pix" image?
It's got more than 4 colours, is that the cause of the flickering mentioned? Doesn't sound practical if the image flickers :/

[HAL6128]

Exactly! This picture shows 10 colours in Mode 1 (B1) by interlacing / overlapping two pictures in overscan mode (384x272 Pixels) and mixing 4x4 colours. The image on a real CPC shows both in fast series (25-50Hz?). Therefore it flickers and is not so smooth as the picture attached. ...but still a cool application. The Batman forever demo from Rhino shows such images (middle and end). Hence he creates a couple of month later that little tool out of it...

I like that one the best.  Maybe cos I ain't so much into Mortal Kombat but I am very much into the nice vibrant CPC palette being used.  Of course it could use fixing and smoothing but for a quick go I like it.

As with ConvImgCPC, I'm looking for a BASIC programm to display a 'Perfect Pix' 's picture, in order to 'remake' all my loader screen of all my games.
If somebody knows how to do that.........

CPC+ version. Mode 0

[andycadley]

Yeah, the Plus really makes it look easy.


Not sure you could display "Perfect Pix" images using BASIC. Two overscan screens is already eating up most of 64K ram purely for screen data, so you've already got to shove the system out of the way.

I love the one from SuTeKH/Epyteor but I didn't succeed my full overscan (the floppy routine I used (firmware one) seems using &8000+ area), but got a cool result, here a preview

Coded following french JDVA tutorials youtube videos and adding still more...

A fair effort! ^_^ Attached is a very quick .dsk showing the overscan screen! RUN"VIEWSCRN" to load it, then press any key to get back to BASIC.
However, Carnivius is correct in saying that it needs a LOT of work, but will do as a preview for now!

I will ask Rhino if there is a BASIC loader for Perfect Pix, but I think it would only be viable on a 6128, as you might be able to chuck the second image to the upper 64k. OR... keeping the screen as a standard 320x200, because then you have one in lower RAM (&4000) and the other in upper RAM (&C000) and keep Firmware intact!

The video hardware can't access the upper 64K, it has to be resident in the main RAM. A non-overscan screen might be a viable alternative though.

[Rhino]

Showing a Perfect Pix overscan screen requires the four video banks of 16kb, so you need 128kb and an assembly routine that saves the memory of basic, firmware, etc... in the extra memory, then display the screen and when you return to restore the memory again. This is what the Perfect Pix Paint tool itself does since it has part in Basic and part in machine code and you can show the screen and back to basic. But showing the screen while loading with the firmware would not be possible.
