Hello,

I like to release another core with a new visual feature: scanline emulation.
This is an already known effect in some other products e.g. emulator or the Indivision-AGA flicker fixer to let the VGA screen look like an old 1084 (PAL/NTSC) Monitor. Even on TFT/LCD screen this effect make the whole picture smooth and less artificial looking caused by the doubled line buffering.
Combined with horizontal interpolation Minimigs VGA output has the same look-and-feel as an old 15KHz Amiga monitor or even TV screen.

The scanlines can be disabled by closing the spare i/o jumper pin 5-6. No jumper will activate the scanlines (default). Also in vertical interpolation this effect is turned off. I did not try both effects in combination but it would make no sense to have 2 vertical visual effects on the same picture.

Damn cool!!!
Now, when will the A4000 keyboard compatibility be ready too?

[boing4000]

AFAIK RedSkullDC was or is still working on it. It may not be difficult to do but the A4000 kbd don't provide the OSD control keys. So you will always use a joystick and the menu button on the Minimig board.
Of course this also can be adapted by using eg. +, - and Enter on A4000s numpad while OSD is visual. A bit harder would make Minimig both ps/2 and Amiga keyboard compatible with some kind of auto sense.

@ Boing4000.

Great work. It's great to see several people working on the Minimig core. I hope that when the ARM is released properly that this code in incorporated into that core too.

I have a A4000 keyboard somewhere, looks like a nice option to use. ;-)

Did the dual-floppy drive core release yet?

[boing4000]

Thx Darrin, Minimig will always be interesting to me! As long as the fpga has some space left, all functions can be reimported.
Scanline emulation dont take much space, so I belief it may still fit into the next core release :-)

I can try to make an A4000 keyboard work on Minimig, but this will be a fixed state without auto sensing or switching between ps/2 or amiga key code. Perhaps in time it could be switchable... somehow

Only on the ARM expansion so far (quad-floppy support).

Using an A4000 keyboard would be nice, but my A4000 came off eBay with no keyboard so I've always used a PC PS2 one with it. I do have an A2000 and A3000 keyboard though. :-)

So the ARM expansion is available? :-)

No, it's still in protyping.
The lucky few who got it can play around with both multiple floppies and harddrive emulation.

It's close. There's just a few beta boards out at the moment, but it certainly works. It's plug & play too - just copy all the files to the SD card, remove the PIC with a screwdriver, pop in the ARM and switch on. "Core updates" are now replacing a file on the SD card rather than buggering around with a serial cable.

For those with a soldering iron, you can short out 2 contacts to increase the speed of the hard file access.
