No modification is required. You just unscrew the Sanwa joystick and screw in the Seimitsu.
OK. Thanks for the quick response.
Recieved my Synthesis yesterday. Pretty sure “glorious” is the word I’d use to describe it. I’m going to go with it.
any eta for a restock of the ebony?
you should do a larger production quantity and sell them to reseller to provide easier access for all folks worldwide. if you don’t, fine by me - but at least try to be able to satisfy the demand - because those sticks are too awesome and I’m dying to buy one, but they’re always sold out 
any chance that the new quiet sanwa joystick and buttons will be installed in future eightarc sticks?
We should be restocking in 6-8 weeks. We will try our best to meet the demands of our customer. Thank you for your input.
We will consider this if there is enough demand for it. Thanks for the input.
How soon do the sticks ship once ordered? How long do they usually take to be delivered within the USA?
Hi Gelohk, we will fulfill your order within 1-3 business days, but most orders go out same day. We are located in California, so it will take 2-5 business days via UPS ground depending on where you are located (East Coast taking the longest time obviously).
ok. thanks.
Hey eightarc
When are you guys gonna restock again? You said 6 to 8 weeks but for which color is that (hopefully you weren’t talking about a general restock)? I prefer the ebony one, but I’ll buy ivory or clear at this point, because I just want the stick tbh.
I’m also tempted to buy the eLive.pro RF. Does this stick use the exact same PCB etc as the Fusion’s? I read that the Q4 has a dual PCB setup while the Fusion has a single PCB setup. Which one applies to the eLive.pro RF, dual or single PCB setup?
Thanks
Hello, I recently ordered my first eightarc stick 2 days ago, I’ve been tracking it through UPS site and it says “Order Processed: Ready For UPS” and that a label has been created for it and that’s about it. whats up with that? I called UPS customer support but they said that either the package is either on its way to the wherehouse or it hasn’t been shipped from the manufacturer. Can i get an estimation as to how long it would take to ship from San Fran to Portland, OR? Thanks!!
Its being shipped right now and should arrive in two days 
I think I was just worrying too much is all lol.
My fightstick is gave out on me and i was wondering if anyone knew when the ebony and ivory sticks are going to be in stock.
We should be restocking in 3-4 weeks. The qanba and eightarc joysticks use the same single pcb. These are also used in the limited edition eLive.pro line of joysticks. Thanks!
Glad everything worked out!
We should be restocking in 3-4 weeks for all models.
Are these fightsticks compatible with windows 7?
We’ve only tested on Windows XP but it should work also. If not, you can try the following:
[LIST]
[]Get x360ce from http://code.google.com/p/x360ce/downloads/list and use it like described in the wiki http://code.google.com/p/x360ce/wiki/MainPage.
[]In short:
[]Copy the files from xinput_r421_x86.zip (you also need the x86 file if you have a 64 bit OS as the SSF4AE.exe is a 32 bit application) and x360ce.App-2.0.2.102.zip to your SSF4AE folder (mine is “C:\Games\Steam\steamapps\common\super street fighter iv - arcade edition”).
[]Now run the x360ce.exe and configure your controller by selecting “record” for every button and pressing the desired button on your controller.
[]Especially the left stick directions are important and need to be set to your D-Pad up / down / right / left of course.
[]When you are done hit save and close x360ce.exe again.
[*]Now simply start SSF4AE. It will detect the xinput1_3.dll by itself and if your x360ce.ini is correct your Arcade Stick will work as it should.
[/LIST]
Thank you for the fast response. I’m making sure to get one whenever there will be a restock.
Any idea when Fusion Synthesis’ will be restocked?
Should be sometime this week!
