Thx for the reply but it dones't import them well.
The high resolution sprites are ok but not the low resolution.
It is another way to do it?
I'm not sure quite which version you are trying to convert from but if it supports image export you could do it that way, alternatively use the binary method as suggested and just manually set each "low res" (multi-colour) sprite to multi-colour mode and maybe tweak the colours until they appear correct.
