Btw i just googled the Vega+ to refresh my memory and almost immediately stumbled upon a very familiar name from these recent events. And next to the words "lies", "paid" and "scam", no less. So it seems i shouldn't have been surprised by the actions and personal qualities of the current WoS staff. Maybe now being a lying crook is even a requirement to be in. :roll:
Many of us remember well and haven't forgotten the history of censorship and bans of Fogarty's company on wos.
Probably you didn't know it and that was why you were an easy target, but some of us who have spent more than a decade there, know their methods very well.
You reacted impulsively to their provocations, but you were absolutely right, because you noticed what kind of liars and manipulators you were dealing with and you told them straight in the face.
So, relax...and don't pay attention to some wos trolls, this is Spectrum Computing forum.
Their mockery, lol and facepalm performance, simply doesn't bring much success here.

Destiny Mission looks stunning without color clash, and I'm wondering about Arkanoid 2 :lol:

BTW: is there an English version for the documentation about the format?

One of the oldest ones... it was just a test of full color-per-pixel repaint of something. The background in Destiny Mission was chosen to get most effect for the least amount of work. Usually i prefer to change sprite colors.

Maybe i will do Arkanoid someday. And you people may name other titles you'd like to see improved.

Not even the russian documentation is properly finished, some changes happen time to time and it needs more tutorials. Starting the translation now means more work in the end, and it's hard enough for me to write so much in english already.

This is a hoax. Everyone knows that Destiny Mission doesn't have any sprites.

Those are the ones that really poke my interest, no extra colors but just the lack of colour clash, but I like the other ones also, they are not overdone as most of the Spec256 ones.
Oh, and how you colorized vector games like Total Eclipse and Academy? Are those using the new video mode you mentioned?

Haha ok, no pressure then, but I showed your work on a small Spectrum group and some artists are intrigued :)

that's mainly because i'm too lazy to make a full repaint :lol:
(and an extra reason i dislike xored sprites, as these need it)

no, ZX textures are very similar to sprites - read screen, read texture byte, mask it at the polygon edge, write screen
so recolorable the same way, replacing the corresponding pixels in ULAX memory with solid color or simpler pattern
hardest part is to preserve attribute effects, reloading the (limited) dynamic palette at the right moment
in Academy (as it is a multiload) the palette had to be constructed from any attribute with some tricks

also i recommend playing the freescape games with adapturbo (LAlt+F1 toggle, LAlt+F2/F3 & RAlt+F11/F12 tweak, see emuL-info.txt)

I would really like to see Sabre Wulf, Atic Atac and Heartland with colorful main sprites and without color clash.
Just a few questions ...
How difficult is the recoloring process?
I remember the ULA + recoloring was relatively easy and really fun.
Are there any tools, that make this process easier?

it depends on how well you understand disassembled z80 code and how complicated this code is
easiest ones (like Phantis 2 - 1st tutorial is about it) took less than one hour, hardest ones needed several evenings
and then most of the time went into the actual repaint, finding all the graphics to repaint, and checking after

besides primitive homemade tools to match the colors and to repaint sprites when i have to, i use mostly:
this very emulator for finding the gfx routines and figuring out what these are doing exactly (see pics in the tutorial)
ZXSpin to get nicely formatted disassembly of the aforementioned routines
Xpeccy for finding gfx data and sometimes tracing the code

...and i hope we will have this in working condition before long - viewtopic.php?f=9&t=2155

Hah! Well, call me oldschool because I like that kind of minimalist work. Another one: Chuckie Egg

Oh I did that! In fact, my first gameplay was Red Shift on turbo mode and it is a blast.
