As Tulip computers, unlike Amiga Inc, have no problem with the homage to Commodore computers that is the VICE suite of emulators I don't see the point.
Download VICE, double click to extract, drag and drop any T64/D64/TAP file onto the running emulator and it loads and runs automatically. No roms to buy legally, no extras to download. Perfect and simple as pie.
If you want to spend money on C64 software show your support by purchasing real games from Psytronik or others producing software in 2012 (you are also supplied with an emulator friendly copy of the game via email).
I wish Amiga games in 2012 showed the same level of artistic and technical talent as the C64 releases of this decade alone.
