Re: Wiki website problem
I guess at this point it's likely that the Wiki isn't coming back, due to the spam problems discussed above?

Re: Dread - doom like game from Amiga
Why not perform texture scaling only via planar oriented computation? And use already 16 color planar based textures? The texture algorithm needs to be redone, but these machines are planar based, both ST/E and Amiga One imagines that the underlying renderer runs one column at a time; if so then th...

Re: Lemmings with 2 mice on windows 10 - Atari Steem Emulator?
To be fair, it’s almost wilfully obscure — the only reason I noticed it is that Apple more or less forces you into direct device enumeration and management in order to read joysticks, and I ended up being curious about the Windows equivalent of that.

Re: Lemmings with 2 mice on windows 10 - Atari Steem Emulator?
Sorry to be contrary, but as of Windows XP software can accept input from multiple mice independently by using the Raw Input API. Ditto on the Mac you can use the HIDManager, and it's pretty safe to assume that Linux has something. EDIT: Googling for the Linux answer, somebody has created a cross-pl...

Re: Favourite 3D games that look visually pleasing?
Yeah, I do remember it being a demo too, I remember it on screens constantly in my local computer shop, I think for the Archimedes. I remember the fuss at the time because it wasn't just a 3D game, it was a groundbreaking 3D game, shadows, lighting, pretty smooth rendering and little details. The s...

Re: Slowing mouse movement
$0b sets a movement threshold. It doesn't set the number of pulses needed for a change in position, it sets the minimum distance the mouse must have moved before a message is delivered. The message will still communicate the full movement. So e.g. if you set the threshold to '2' then you guarantee t...

Re: Data register sign extension
It's likely, as the Programmer's Reference Manual is entirely explicit, directly in its description of MOVEM:
"In the case of a word transfer to either address or data registers, each word is sign-extended to 32 bits," (P4-128; P232 of the PDF)

I wasn't talking about all the editions you made to the wiki page. Okay, then it's pretty clear: I'm way off the mark here in my tone and manner of response.

Re: Understanding the Union Demo's Opening of left and right borders
Sorry, but to be honest, I think it is more confusing now than it was before your corrections. I would remove completely the reference about the delay, it doesn't add anything, IMHO, quite the contrary. I strongly disagree. Furthermore, it's a wiki so there's a full edit history so nothing has been...

Re: Atari Mint on 68k Macintosh
You would need a VDI driver, for example for fVDI. Not impossible, but still some work. Maybe for monochrome you can even use the 1-plane driver (dunno how the video memory in a Mac is organized). It's the most trivial layout possible — it's linear from one of two selectable start addresses*, with ...

Is there any option to include support for Pasti images in FlashFloppy and/or HxE? I'm sure it would require a cooperation of developers on both "sides". I've been sticking my nose into how to reconstruct a flux stream from Pasti files in the last few days and it seems to be non-trivial —...

Re: Understanding the Union Demo's Opening of left and right borders
It was meant to communicate only: there'll be delays, but I'm not going to tell you what they are, or even whether they're the same for every row. I'm not sure there is any need to be that vague, at least regarding the simultaneity of multiple signals affected on the same row. Considering there is ...
