Modding a 360 HRAP to use on SNES

[linko9]

Hey yall, I want to mod my 360 HRAP3-SE to work with my SNES. Problem is I have no experience whatsoever doing any mods at all, soldering, etc., so I want to know what it would take to achieve this and how difficult it would be. Haven't even opened up the stick to see what it looks like inside. I do have a friend with soldering/wiring experience, so that's something.

I don't particularly care if I lose the 360 functionality, this can just end up working with a SNES. I would ideally like to be able to use it on PC as well, which I guess would mean losing two buttons when using a SNES to USB converter, but if there's a way to somehow add SNES connectivity to the existing functionality, that would be amazing.

I assume one way to go about it would be to take apart a snes controller, revealing one of these PCBs, then solder the wires from the inputs to it?

I also came across this contraption:

which seems like it could serve a similar purpose, perhaps to work with multiple systems, but I haven't really looked into it (and it seems to be currently unavailable).

Anyway, if anyone has experience modding a stick to work on SNES, any advice would be much appreciated. If it seems too difficult I may not go for it, but if it's reasonably feasible, it's something I'd really love to do.

If you don't want to replace your entire PCB (and I wouldn't), you can just wait for this to come back in stock and have your guy do the soldering:

Awesome, that looks like just what I want. Hope it gets restocked soon! Do you know if this will introduce any input lag?

According to this guy, only 1 ms:

What about input lag?

Your lag, if any can come from 3 sources in the chain:

360/ps3 input controller -> Undamnded USB Decoder -> Donor PCB

There are about 16 ms in one frame. Typical input controllers can range from 1ms up to and beyond 14ms. The Undamnded USB decoder has been tested to show that it only introduces 1ms of latency into the chain. Since the undamned usb decoder and donor pcb will be constant in your chain and can be expected to be about 3 to 6 ms in latency, the biggest contributer to lag will be your input device. You would want to use something that keeps you within that frame window. You can use the data on this page (http://www.teyah.net/sticklag/results.html ) to help you figure this out. To be honest, we are talking about ms differences here and in most cases below 1 frame. Many of you will not notice the difference.

Why this convertor over other commercially available convertors?

There are severl advantages to this convertor over commercially available ones.

1. Since you are using officially licensed controllers as your donor pcb, you do not have to worry about your convertor being patched out in a firmwared update.

2. No lockout by the ps4. All commercially available convertors on the market have to deal with being booted off by the ps4 after 8 minutes. This is due to the convertor not being able to authenticate itself via bluetooth to the ps4. Since you are using an officially licensed controller pcb to directly communicate with the ps4, you will not have this problem.

3. Tournament legality. Undamnded USB decoder has been used at EVO and TFC. It was used to run SF ST on superguns. Simply put, it has no macros, you are coupling it with a licensend wired controller. It is tournament legal

I know they're very highly regarded in the fighting game and Tetris communities. I wouldn't worry about lag!
