Hello RIP-Felix, am glad that i found your post here as I have a very similar, project. It all started with buying a 30 USD pound cable just so I can play sega rally again and ended up with have having 3 DC consoles with almost every mod except an original GDEMU as I could only find clones online and am on the edge of getting dreamport. Although I am some kind reluctant after reading your review.
I was planning to get the dreamport for two reason 1- the console looks better without controllers connected specially after adding RGB lights to the controller ports and a custom shell. 2 - Being able to turn on an off the console remotely. However, after learning about the input lag and the 2-3 seconds disconnection issues I Am kinda putting this on hold. would you buy it again after knowing those issues?
Thanks
