Basilisk II Atari

I certainly don't mind if you use them. :-) I adapted some existing ones, after all.

@Badwolf,
If you have the time, would you like to try this test build?

My desk is full of STE at the moment, but will report back ASAP.

Cheers! These integrated nicely :)

It feels ok for less intensive stuff, at least in Hatari.
It's never going to be great when running something that modifies a huge part of the screen every frame but for normal stuff it does feel alright-ish.

TT will get a Mac8bit->Atari4bit thingy as well.
It's not going to look super when reducing colors that much, it's mainly to allow 8bit only things to actually run.
I suppose it'll look similar to ScummST, and OpenDune in 4bit mode.

Or maybe not..

It appears changing the font and icon size makes the desktop just about usable even when scaled from 640x480 -> 320x480 for the TT's 256 color mode :)
Usable enough for locating and launching some game at least.

Hi Anders,

Sorry it's taken a little while. Building & editing has been going on!

Unfortunately I couldn't make it work. I tried a few things, but this is the extent of the issue:





Basically either the screen starts to redraw after initially going to the black/white dither pattern and stops part way (MiNT) or it fills with a solid colour, but then nothing else happens after a fair old while.

I tried with and without overscan (so 768x480/TC and 640x400/TC) with and without MiNT and even with and without DFB1. The latter (stock falcon) didn't even get to filling the screen the first time, I'm afraid.

No worries! I'm just grateful for the help and there's absolutely no rush :)

I started refactoring all that video code after making a big mess of everything adding that emulation feature.

This here is a work in progress that:

Many things changed or moved around so it's hard to guess if those old issues are fixed or not.
It may or may not cause new issues though :)

You can run it in 4bit, 8bit and 16bit modes (I recommend 8bit)
And of course mono which doesn't need emulation.

It's the same thing with ramsize as before.
Use "ramsize" in basilisk.inf to give the Mac at least a couple of megabytes less RAM than what you have free.
(I will make it do the right thing at "ramsize 0" at some point :))


Oh, and this test build should also work on Atari TT.
TT Medium and Low are supported through emulation.
ST/TT mono is native


(68040/060 is not fully supported yet. Video emulation should technically work but it will be horribly slow until I've finished the supporting MMU code for these cpus)

[agranlund]

This one is almost identical to the one above. Only change is a fix for 4bit mode on Falcon, and palette restoration issues on shutdown.

Hmmn.. I may have gotten a bit carried away :lol:

ST-Low resolution emulating 256 color 640x480.

This is cooler than a polar bear in shades. :bravo:

@agranlund can this take advantage of NOVA graphics?
