TI-99/4A Texas Instruments TI99 4A Sega Genesis Modded Controller Joystick Mod. This custom made mod controller allows you to play all your favorite TI-99/4A games using an original Sega Genesis gamepad. The controller allows you to use the single fire button, and adds a jump button for games that use Up on the joystick as the jump button, and a down button for games that use down on the joystick as an action button. 



This controller is hard wired to only be used for Player 1. This controller can only be used for player 1, and is not compatible with TI-99/4A 2 port joystick adapters. I sell Atari 2600 controllers that can be used with the 2 player adapter.


The alpha lock key must be in the up position and not in the locked position, for the controller to work. 


 

This controller is custom made with a genuine OEM SEGA controller. I don't use 3D printed parts, Retrobit, Classic Controller, or any cheap knock off imitation controllers. 

All resistors, capacitors, integrated circuits, and other components have been removed to make this controller 100% safe to use on your original hardware with no risk of damage. 

This controller has been completely refurbished and cleaned so it operates as good as when it was new.
