Thanks :)

I've asked Sigrid and she said you might be using an old version of
Android? That might be why it's crashing.

That's right, Oquonie has more assets that can fit in uxn's
addressable 64kb, so to access these, I copy them into addressable
space with the System/Expansion.

Hi Kyle,

I've just tested and it works well :) It'll make more sense once the
visual editor is going I think. A lot of the examples in etc don't do
anything, like particles.bean? what's the trick to run those?

I saw in your README "After switching to the drifblim assembler, I'm
having some trouble assembling using uxnasm, so drifblim is
required.", I was able to assemble with uxnasm and drifblim, the
resulting rom is the same, are you still having that issue?

This is a good idea! So it’d be used like JMI +&label, right? In the example above, you can already write JMI 0100, as it’s valid uxntal.

I've had the time to check most of the 100r roms, and it doesn't
really break compability, there's some cursor drawing artifacts that I
can easily fix, but otherwise, if you think that it'll benefit your
projects, I'm willing to push this change to the repo, and update the
docs.

It'll take me a day or so to patch up the little drawing issues.

We’ve been toying with a partial clear on 0x00 colour today. It seems like it wouldn’t be too bad a change to port. 

I think it might only be a matter to change line 53 on screen.c and remove !color. Try it out if you like, see if that’s something that helps :)

Ah yes! It should be one of those cyan, black and white circles. Have a look at devices/screen.tal to see the sprite that should be there.

The blending nibble was designed to handle applications like left, orca and oquonie. Actually, all of Varvara was designed around hosting these 3 projects. 

The blending nibble makes more sense if you’re think about it in terms of highlighting text for example. We had to do a project once where we had teams like you described and had to paint the team colour in a second draw which was annoying. The blending for 2-bit graphics is pretty bad, maybe it could be changed somehow but we haven’t had much success hitting the right balance, or at least not causing as many issues that it was solving.

We’re open to changing the strategy. There might also be something to look into like proper bliting. Like image that beside the pixel and sprite port, there was a screen/blit port, that takes a cmd and the address is to a bliting program. The port would be a sort of xor, and, etc blending, the bliting program in memory could do at once filling a large portion of the screen with some logic defined in the program. Not unlike the expansion port.

Hi Hikari,

It's a good proposal, I return thinking about this myself from time to time.
If we were to change this, we'd only need to do a bit of shimming for
portability, by setting a full tile:

;empty-icn .Screen/addr DEO2
#00 .Screen/color DEO BRK
@empty-icn ff ff ff ff ff ff ff ff

One thing that I've been considering as the main advantage for this,
is to be able to erase parts of a drawing. Sometimes I want to paint a
drawing, and erase a specific selection of it, and this would allow
that. Say, like adding rounded corners to a rectangle by erasing the
