I've been tricked by the same situation a few times. The state was saved to slot 1 by pressing the "1" key, that the driver maps to the Pause button of the SMS console, what I think makes sense because is equivalent to the Start/Pause button of the Game Gear and the "1" key is MAME's default mapping for a start button. The problem is when the "1" key is pressed to select the save slot 1, the action also affects the running emulation. To resume the game, after load the saved state, press the '1' key again to unpause the console and press the button 2 on the control pad to return to resume the game.
