I got the Agetec Arcade Stick for the Sega Dreamcast for Xmas. What a great gift! The stick is built like a tank, and it's meant to mimic a Japanese arcade machine, AKA a candy cab. I no longer had to use the standard Dreamcast controller for 2D-shooters and fighters, which encompass my favorite DC games. The standard controller is ill-equipped for titles like Marvel Vs. Capcom, Street Fighter Alpha 3, Gunbird 2, and Mars Matrix. The Agetec stick is made for those games. But as much as I liked this arcade stick, something was missing. The sticks and buttons felt good, but not great. I read that people were unlocking the full potential of this controller but removing the standard stick and buttons and replacing them with a Sanwa stick and buttons, and replacing the Agetec's 4-way joystick gate with a Sanwa octal gate. Sanwa is the most popular arcade control manufacturer in Japan. They make great looking, durable, reliable, accurate, and comfortable sticks and buttons. I read a couple tutorials about how to do this mod here and here. Looked simple enough, so I placed an order for a white-top Sanwa JLF stick, octal gate, and 6 white 30mm buttons.
I used a Dremel to enlarge the button holes from 28mm to 30mm so that the new buttons would fit. I also removed some of the mounting plastic for the old stick so that the new one would fit, and drilled holes to mount the new stick. I installed the Sanwa buttons and the stick, soldered the wires in place, closed it up, and tested. (All this is covered in the above tutorials.) The buttons all worked right away, but both tutorials had the wrong colors listed for splicing the stick controls. I had to do this manually by testing at the Dreamcast menu screen. After a while I found the right combinations. The correct joystick wire color combinations are as follows:
Yellow > Black
Orange > Yellow
Red > Green
Brown > Red
Black > Orange
The stick is now perfect. The 8-way gate makes fighters feel like they should. The buttons are a bit lighter and more respnsive. Plus, I think it looks pimp in white. If you have the Agetec stick, this mod is highly recommended, especially for shmup and fighter fans. I'd consider it essential.
