No problem your welcome
To be honest I've only had the Dingoo since Tuesday so I'm playing around with that a lot more so it's too early to say but then on the other hand I have maybe 10/12 games for my DS of which I only really play 3 (Football Director/Ketsui/Proffesor Layton)
But on the other hand with the Dingoo I have complete catalogues of MD/SNES/Neo Geo/GBA/NES/CPS games which means I have a never ending supply of great classic software many of which I have never played before so in all honesty I can say I would expect the Dingoo to take the lion share of my handheld gaming.
But again it's personal preference, once you've played the few old games you enjoyed at the time & run out of retro classics you actually want to play (Lets be honest not everything released were A+ titles were they?

) then the Dingoo becomes a bit of a novelty.
Whereas the DS will get continued support & again not all titles will be must buys but out of all the shovelware released there will be at least something that catches your eye thats worth playing.
Like I said I'm privelidged enough to own both, but if I wasnt that well off then for my money I think I'd probably have to look towards the DS mostly for it's continued support.
Although to throw something else into the mix what about a second hand PSP with Custom Firmware??
That will have all the good PSP software available & also access again to Emulators like MD/SNES/MAME/FBA these are regularly available in the sales thread for between £50-£70
I originally wanted a PSP but kept missing them in the forums sales & then noticed the Dingoo which did everything I wanted for slightly less so plumped for one of them instead...but I would still like a PSP myself at somepoint mosytly for the Bleach & Ikki Tousen games that were released in Japan so in a couple of months I expect I'll be adding one to my collection too
Anyway hope thats given you something more to think about.
