Scandoubler / Flickerfixer solution!

[MarkAshley]

Interesting. I have seen composite to VGA/XGA adapters but never RGB to XGA. A bit pricey but better than the current price of scandoublers...

Nice one!

If the adapter converts the Amiga RGB output to composite and then converts that composite signal to XGA, then yes you would experience a loss of quality. But if the adapter converts the RGB signal directly to XGA then I would imagine the quality would be the same as with a scandoubler (because that's what it is...).

[MarkAshley]

What type of input does your one have?

[MarkAshley]

How are you getting the scart connection from your Amiga? And your xbox? If you are using scart cables which contain the RGB signals then the effect should be identical whether you connect the Amiga or the xbox. But scart cables also contain a composite signal - so be careful your Amiga cable is not using this signal instead of the RGB, otherwise you will suffer poor quality.

[MarkAshley]

That is strange indeed. Maybe it's to do with the strength of the signal? If the older devices are using a slightly lower voltage in their RGB connections then the conversion to XGA may be more lossy than with a more modern device.

Sounds like a long shot but it's the only thing I can think of!

If anyone is interested in doing this, here is a schematic for an Amiga to SCART cable:

I went to Maplin Electronics today to get the components but unfortunately couldn't find a 23 pin D connector  :-?
