The main goals of this Genesis-Plus-GX port are:

• Have a basic but user-friendly user interface on non Windows devices.
• Use a recent rendering interface for speed and effects support.
• Cross-platform and code portability.
• Easy updates of genesis-plus-gx core (no modifications to the original sources).

Features

• Support save states.
• Support 2x, 3x, fit, fit 4/3 and fullscreen hardware scaling.
• Support hardware filtering (shaders).
