SpecEmu v2.8 emulator released

Dunno if this is the right place for this post (other than it being in English!) but I've released SpecEmu v2.8 for PC/Windows, emulating 48/128/+2/+3/TC2048/Pentagon 128K emulation.

The main new additions from the previous release are RZX capability (with rollback recording) and a (slightly rough) implementation of the flashing quirk and 4 brightness levels of the 48K/128K ULAs. I'm told these quirks don't exist on the +2A/+3 ULA but I'm not able to test those myself.

I've put a few rather simple examples of the effects here.

In the emulator there's a "ULA colour ramping" option in the Display options which turns the quirky behaviour on, or it can be toggled on/off using the ALT+C keys. I really need to find a better name for it...

Now what I was wondering was if any of the Pentagon (or other) clones show anything like the same effect with some of those tests programs. Though to be honest, my Pentagon knowledge is lacking to the point that I don't have the slightest clue how closely those ULAs might be based on the original versions so this might well come across as a daft question to everyone :v2_rolley

1. Very convenient emulator.

2. The worthy competitor Spectaculator.

Thanks for the emulator !

The screen twitches

Is there any way to disable bilinear screen filtering in emulator?

To be honest I can't actually see what you mean in that part of the demo. But then I've only just dragged myself out of bed so maybe it'll become more obvious to me after a barrel of coffee :)

Not currently unless your graphics driver gives an option to turn it off for DirectDraw. Most only really let you set options for 3D performance as far as I know.

There's a method I could use to force it off but it'd give quite a performance drop in display updating, though not anywhere near the point that a reasonably modern PC wouldn't be able to handle.

g_pd3dDevice->SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_NONE);
g_pd3dDevice->SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_NONE);
g_pd3dDevice->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_NONE);

I've already added the option to turn it off in the development version :)

Nice emulator as for me...
Finally I did see famous "rain" ULA effect:)
Are there any hot keyz for debbuger?( clicking buttons is not comfortable, imho ).

Sorry, not at the moment. I need to see to that really...
