Yes, they have released a VGA version end of last year. Resolutions are 480p (60hz) in NTSC and 576p (50hz) in PAL. The 50hz in PAL has its own advantages and disadvantages. No buffering/conversion to 60hz is required and there is no judder/stuttering. A major disadvantage is that 50hz over VGA is not a refresh rate commonly accepted by LCD/TFT-displays. Some are able to sync, some are not.
When they would have used a real video connection (e.g. HDMI or Component), this wouldn't have been such a problem since most LCD-TVs (at least the European/PAL-ones) accept e.g. 576p50, 720p50, 1080p50, etc.
The only solution are VGA to HDMI or Component transcoders or to add a PAL-upsampling to 60hz (if this is possible with the current hardware).
The C-one fpga64 and chameleon beta cores have the same problem.
The actual Chameleon uses VGA and outputs 800x600 native with a scan rate at 72hz and support to some degree a programable VGA output so it can be adjusted in software, even from the C64 side via pokes. The tearing effects of the VGA output is reduced by double buffering the VGA display.
At 800x600 VGA output at 72hz working for both PAL and NTSC, most display work without the 50hz problem you described.
This is detailed on Page 9 of chameleon_progmanual_beta5.pdf .
Of course now also the Minimig core is out for the Chameleon as well. It has a few bugs still but still very usable. It does output 50hz for the PAL display so for PAL Minimig support you need a 50hz VGA display. NTSC is 60.
So many options now. Fun times.
