I'm going to start an FAQ on my forums ...

Think of the hardware as being very close to the original. So for original modes use DVI to analog scart / monitor. This will work fine. It may work with a DVI to HDMI cable (separate audio). Some systems do, some don't. I am working on an on-the-fly HDMI adapter which will legalize the line length with adding only one line delay (so no tearing).

For high res you have the choice of DVI/HDMI or Analog.
/Mike


1. Yes a FAQ will defenitely help :)

2. DVI + Audio -> analog scart - do you have pinouts for these? Maybe you can include it in the FAQ?

3. When you say some sytems work, other don't I assume it depends on the TV set?

4. So if I use a DVI to HDMI from Ebay i will get screen tearing (like no Vsync effect?)

5. In the past I have used a Minimig 1.1 @ 50hz via VGA with my Benq LCD monitor (50hz capable) - it worked without any problems. Don't know if that means anything, thought I'd mention that :)

Just a quick tip for those stuck with displays that require video and audio integrated into the same HDMI signal:



The converter has input for DVI + S/PDIF and output for HDMI signal with video and audio integrated. All for $69.95 (NZ dollar?).

Alternatively wait for a more powerful FPGA with Rocketport etc and DVI connector that will make "upgrade" possible ;)
Anyone that can find a cheaper one?

That sounds pretty high.  I bought the one below from TigerDirect for $29.99 USD and I'm quite pleased with it.  That's $38.46 NZD.

Just what the doctor ordered, but it seems we need a special cable to use with the FPGA so we get a perfect picture.

Do you mean this cable for the audio or is the Replay using a non-standard DVI output?

You shouldn't, what he means is that he's doing a convertor and so that the convertor doesn't add tearing he's doing it a line at a time.

Hmmm - so some games may work, others not? How will this affect games exactly.

He means some TV's will work, some won't. For OCS the timing is always the same, so if one game works they all should. If you're using ECS/AGA then you can change the timing, but I don't know if any games actually do.

Sorry for my stupidity, what convertor is he doing?

"All" I want to do is to able to play ECS and AGA games using a DVI->HDMI cable at 50hz without any scrolling or tearing issues.

Is that possible?

Will certainly work DVI -> VGA. Will probably work with DVI -> DVI. May well work with DVI -> HDMI.

HDMI seems to be a bit fussy over the pixel counts per line, not so fussy over the exact frequency. The idea is to retime to a HDMI line standard on the fly.
Yes, the 3.5mm to RCA cable is what you need for audio, I do the same.

Could there be legal implications by bundling a board with DVI output and a DVI-to-HDMI adapter?

No, I don't believe so - HDMI is a super-set of DVI and DVI is open.
All I am doing is creating a slightly different DVI format which happens to be compatible with HDMI.

@mikej: The new FPGA ARCADE page is up at last! Congrats, it looks very nice :)

It says "the Atari chipset is available"..where? How can I lay my hands on the shiny Atari ST core and go for some software blitting and crispy AY sound on my Fpga Arcade board?? She's been waiting for almost two years for some action :D

Ohh cores, where art thou?

Ohh got the new website up now Mike :)

Is there a tutorial or guide for how to get developing a core for the FPGAArcade?
Getting setup to modify the cores and create new ones can be a pain, especially with Xilinx's development environment.

Well, I just created the FAQ/how-to section ... look under Forums

Building (semi) public SVN server now.

To build the ARM code you type "make"

To build the FPGA image you run "build.bat" from the core root directory in a cmd prompt (I'm not an IDE sort of chap)

There is a demo design which shows how to hook up to the support libs.

We are getting there ....

"~68030/50mHz" I think it should read 50 MHz or it would mean that the device crawls along at 0.05 Hz ;)

amiga with big A because it's a name.

Mainly active developers - thought you guys would like stuff to run on the boards ;)
