Does it display as grey initially?

Yes for a bit of a second.

It'll keep doing that so long as you have that RecallPic in there. What's the RecallPic for, anyway?

To Recall the image I drew before the loop, I know it's not needed in this particular case, but I'll need it later.

Note that if you are using greyscale, you *can't* backup images using Store and Recallpic, because those store to the backbuffer, which is used in greyscale.  Remember, to display greyscale, it uses both L3 and L6.  When you StorePic, you store the image to L3, which is not the right place to backup an image if you want to do greyscale

Ah, thanks then, I won't use the recall/store pic thing anymore then :)

Is there a way to reverse a 1-pixel row and/or column?
Not in 8-pixel chunks, but pixel-for-pixel?

Probably the simplest way would be to copy it to a piece of free memory and then copy it back pixel by pixel but with inverted X coordinates.  Slow, but simple.  What are you looking to use this for?

Well, the screen is usually stored in 8-pixel chunks, so if you want to do it in pure Axe I guess you'd have to use a bunch of pxl-Test(s or something :-\

He wants to laterally flip it, not invert it i think.

Er in that case, what do you mean by reverse? Change each pixel or flip a block of pixels?

Not invert the pixels, but flip them.  Like, 11100001 would become 10000111

Just had a thought.  Would FlipH work?  Thinking about it, sprites are 8-pixel-wide chunks...
Actually, just realized sprites are 8*8 and there's 12 chunks of data :P

What are you looking to use this for?
A way to flip the screen 180owith an animation, and b/c there doesn't seem to be a plausible way of making the screen look like it's rotating...
This post and a couple of others after it.

Instead of turning it, how about mirroring it instead?  The way I achieved the effect in the post you linked to was to simply clear the screen towards the center, and then redraw a flipped tilemap from the center.

I have a 4*4 sprite (no tilemapping, just a sprite).

I have another sprite, 4*4.

I know the X and Y coordinates of both.

How to know if the latter sprite is touching the first one? Is it a too long code?
