first answer the following question:
if i break my vci case, can i afford to buy another vci to replace it if it comes down to it?
if yes
then = go for it
if no
might wanna look into selling yours and just buying a premodded one (unless you can pay ean to mod yours? not sure if he’ll do that)
This site does sell a kit with a pre-cut vci case, arcade buttons, and a step-by-step guide. You might just wanna buy that.
really? where do i find the pre-cut cases???
u cant buy the cases pre-cut
I think the safest option if you are not that confident is to file the holes out carefully.
So, are you saying if I purchase this following product:
And if I attach this to an ordinary power drill then I can make my own holes in my VCI-100? If this is the case then I think I’ll go for it. However, if some more technical persons among you can advise me then that’ll be great.
Just another part I’ve found on Ebay:
I’d like to attempt this mod myself without going to a specialist but I need someone with metal work knowledge to let me know if it is possible (on a budget) without destroying my VCI-100 case.
If worst comes to worse and you mess up the holes you can glue a sheet of acrylic plastic onto the back of the VCI-100 case, fill the holes with two pack car filler and start again 
Dont use a hole saw
Hole saws are bad news especially if there is some sort of preexisting hole. Hole saws require a pilot bit in the center. even those with bits will walk and hole will not be the exact measurement. I used to build race trucks for a living and even with $150 hole saws and $15000 drill press, errors can happen. for exact fit go smaller and file or dremel to spec. Just ordered my buttons today. I am just going to file to what i need and use filler and paint the whole vci so i can label it. Im in to rush, i want it done right, not right now. I will photograph progress and post for any interested. hope any of this helps.
what are you guys paying at shops to have this done for you?
Could you photograph and or video your work…I am also looking to get Arcade buttons on my VCI-100 and can’t find a proven and well documented way. I appreciate anyone to give me some more options and suggestions.
