I just picked up a used Soul Calibuir II stick for the PS2 and I plan to mod it. I won’t be using the stock buttons so they’re up for sale. They show a little wear from use but look fine.
I’ll include the green balltop with the buttons so you’ll have a matching set.
$26 Shipped for 6x Green Namco-style buttons and 1x matching Green Balltop.
