The game the adventures of batman and robin for the Mega Drive (Pal) doesn´t work on the retron 3

DirectX is a set of tools. Each newer revision gives the developer new, more powerful ways to produce the audio and graphical effects gamers always seem to want more of. Graphics cards that support these newer versions can execute this code, while older ones often can’t. Also, these cards have larger, faster, dedicated pipelines for this, often exponentially increasing their performance. Yes, newer versions ARE magic graphics power pixie dust – developers CAN just slap on new, more expensive but better looking shaders, however many of the more advanced features WOULD ideally be implemented during development.
