I have a test rig and a special FPGA build - thats the advantage of having an FPGA :)

Sorry to change the topic. I am just curious on where in the run the daughterboard is :-)

What is the current focus as of today, and when do you think the daughterboard might see the light of day for beta-testers ? Ballpark estimates are more than adequate :-)

I don't think MikeJ has had much time to work on finalizing the daughterboard yet.  He has been busy with final assembly and testing of the 48 FPGA Arcade Replay boards he produced and has a full time job AFAIK.

I too am anxious for the daughterboard to be finished, but don't expect it for another 6 to 12 months.

Hope all is going well with your assembly and testing Mike.:)

The daughterboard is coming along in placement, and I picked up most of the components for the test board. I'm busy with testing, ce marking and the rear panel at the moment, but nearly there. The website is also taking a lot of time to get up.

I am hoping to get the daughterboard PCB produced on my next trip, early Jan.

Any news on the boards?. Hope all is going ok and there were no problems manufacturing.
This waiting is becoming a pain :)

Sorry for the lack of updates, I have been traveling.
Still testing but starting to ship out. I'm mailing people this weekend asking to confirm price, address etc.
Cheers,
Mike

@Mike: Awesome news!! But one thing I am still eager to hear is whether the functions of he daughterboard will be available if I run a core with 020 soft cpu instead of booting up with the onboard 060 cpu.

Yes, you can use the daughterboard IO if using the cpu on the main board. In fact, the daughterboard can be depopulated and used just for the IO.

One word: AWESOME

BTW: Does the daughterboard have some IO connectors so one can connect future expansions aswell ? (not that i think I need that) Do you see a rev#2 of a daughterboard with other options in the future ?

Just curious of the roadmap :)

Stupid question... what resolution (resolutions?) does this output at using the DVI connector? Will there be an option to have the hardware to say, double the resolution in size (triple?) rather than leave it to the TV to upscale?

I'm sure there will be a de-interlacer for hardware bashing games.

As for the desktop, I would hope that someone would eventually create monitor drivers for the following resolutions to drive the television at its native resolutions:

Widescreen: 1280x720 (720p), 1280x360, 640x360, 640x720
Widescreen: 1366x768 ("HD Ready" television and cheap monitors)
Standard: 800x600 (400x300, etc), 1024x768 (512x384, etc), 1280x960 (640x480, 320x240, etc), 1280x1024 (stupid 5:4 resolution)

I don't know if the hardware would be able to support the following:

Widescreen: 1680x1050, 1680x525, 840x1050, 840x525
Widescreen: 1920x1080, 1920x540, 960x1080, 960x540, (480x270)
Standard: 1920x1200, etc

What I meant is this (all hypotetical ok :P ):

Say an Amiga game has a resolution of 240p, and I connect the ArcadeFPGA to my 1080p. Instead of feeding the TV 240p and let it upscale, would it be possible have the ArcadeFPGA to quadruple the resolution and leave the extra remaining pixels "empty" (black border.

So, let's do the maths....

240p x 4 = 960p
1080p - 960 = 120p / 2 = 60 extra pixels on top of bottom of the screen.

In the case of using a 720p resolution, it won't be possible to have the resolution quadrupled, because it wouldn't fit, so instead we'd do:

240p x 3 = 720p
In the above scenario the picture would fit pixel perfect without any margins :D

Is the above possible, or it is a sign that I had too much wine during today's dinner?

Thanks!

PS The idea is to avoid using the TV's upscaler which usually suck

I think it's doable.

It's when you need cosinustransform in FPGA that things get slightly more complicated..

You need what? :P

BTW are there any good videos of Arcade FPGA running a few amiga games? I can't find anything decent.
