Quick question, are Sonic 1 and 2 the Taxman versions?
No, they are direct ports of the emulated versions of Sonic 1 and 2 from the PS3 Genesis Collection. They are far from bad, as I found them perfectly fine, but they could be a lot better.
So, sadly, they are not the great Taxman ports that was made for iOS .
At the very least, the PS3 version of Sonic CD IS done my Taxman .
