Conversion Capers: Rygar

[Amiga1992]

Is there anywhere we can take a look at how this is progressing?

Download the .ADF from sandruzzo's Google Drive:

The disk isn't bootable though so I usually run up my basic WB 3.1 .HDF and run it from there

Yeah, I know what you mean. Quite hard to find in 69 pages of posts

...personally I've bookmarked it for easy access

Ok, I have finally done some things

1. Ryggar sprites are sharing the same 16colour palette with enemies and are using first colour registers 0-15 (hence 4 bitplanes)

2. There is a new copperised 15colour background using only 4 colours in single line.
I have optimised coppermoves in the background so in single line you have to change only one register and limited the overall copper moves.
The background is little worse but DMA is optimised.

I hope i did not fucked something, as i am doing it literally letter by letter.

Some time and I'll put into test. So I have to change the whole gfx, background as well?

[Trachu]

I put also the tiles coz i was not sure i was using the right palette, but it should be the same.

As for the top and bottom I suggest reorganise it.
On Top we will use only 4colours 2 bitplanes.
On down we will use 4 bitplanes 16colors and we will move medals here also.
This is what i propose.

I'll do my best. We still miss some frame from enemies when they are hit on top.

[Trachu]

I guess someone is working on extraction all enemy sprites, right?
Or they have been extracted before and i missed it???

I'll do some test here to see how much horse power do we have. I need this files on iff format

I don't know. Man Should I convert all the gfx again?

[sandruzzo]

@Trachu

Rygars' frames in the package arent' the ones that I'm using, can't use it. Even tiles arent' ok.

[Trachu]

Previously i was working on incomplete set, this one is complete set of Ryggar sprites in all 13 colours (previously 12)!!!

Yes they are in different places on bitmap but all of them were alligned into 32x32 blocks.
You need to rearrange your code, but this is ALL.

I still have incomplete set of Enemy sprites and their animation, when i will have the complete i will convert them to fill the gaps in the animation and you will have to rearrange your code again. Unfortunatelly if we dont have everything at once this is what happens.

Man, Can you better arrange rygars' frame? Take a look to run, frames ae spread too bud, and I miss the reverse ones.

New parallax in place, working on copper list

[sandruzzo]

@Trachu

Mate, you gave me the copper palette wich is 8 bit!!! We only have 4 bit for each color, so yuo should remap them. ex:

#LINE0
;SPRITE COLOR00
COLOR00 = 0 85 221 ; too much here!

we can have 12 bit palette not 24 bit!

[sandruzzo]

@Trachu

Beside line 0, I've seen that you're changing only one color for some lines. Are you sure that's ok, in order to have 16 color parallax? I thought we would have change 4 colors for each lines...

Just to understand

[Trachu]

0 85 221 in RGB12 means R=0 G=85/17=5 B=221/17=13

In order to optimise DMA access some lines contain only 3 colors in line, hence we can change only one register in one line and second in another, because this particular colour is not used in this line.
This is because I want to have as many available odd cycles as possible to use by CPU or blitter, so our copper can not interfere with sprite DMA. The optimal would be sprite dma ends, copper starts.

Line=0 means first line of the background, which is 40something line of display.

Ok Mate, I'll do it. I know line 0 means line 0 of sprite

We're doing better than coin-op? What about trying 64 colors just to see..

[sandruzzo]

16 colors parallax here!

[Trachu]

you have forget to update
this initial settings.
#LINE0
;SPRITE COLOR03
COLOR19 = 34 102 187
COLOR28 = 34 102 187

one of those registers is set, second is wrongly set.
This whole first line should be set at the very top first colour settings for the whole screen.
Also the bottom of the background is coveed by the ground, you need to move the whole background about 10px up.

You should go for 256 px and I will want to have 64 colors here as well.
I was convinced using all sprites for 128px wide paralax is our innovation here, unfortunatelly it is really hard to find something new.
It seems it was indeed used before, together with 32colours

So we have to go for 64px if we would like to have something new.
