【Rare】Includes Bonus Item Neo Geo Dedicated Joystick【Retro】

I purchased this at a shop in Akihabara that used to sell arcade boards and other items.
I believe the shop staff created and sold this by using parts and a box intended for playing on arcade boards.

The parts used are the same as those found in arcade cabinets, and the bonus items are a few spare buttons that were used in the Capcom Mini Cute cabinet. I cannot guarantee if all of them are usable, as shown in images 9 and 10.

This is for home use Neo Geo.
I believe it could be used with either the cartridge or CD console. Please check the connector shape in image 3.

I tried various joysticks at the time, but I believe this joystick was of the highest quality in terms of responsiveness and input accuracy.

Regarding the condition, it shows signs of use and dirt from long-term storage, but there is no rust, and it is in relatively clean condition.
Condition is subjective, so those who are overly sensitive should refrain from purchasing.

Why not add this to your collection?
Thank you for looking.
