A couple of months ago I purchased an eightarc (Qanba) arcade stick – the PS3 Pearl. I had been using a MadCatz TE (MvC2 edition) for over a year and was very happy with its performance, but I wanted an all-white stick and planned to do some other customizations (e.g. artwork). I was just going to use my MadCatz as a backup in case I busted the new one via the mods.
When I received it in the mail, the stick seemed to work fine during “testing” in practice mode on Tekken 6 (my main game). I made a small mod to the stick right away (I spray painted the USB cover white since it was black by default, which to me was clashing with the all-white theme I had going) which of course voided my warranty. It wasn’t a big deal, as the stick worked the “same” after placing the cover back on. But when it came to our weekly gathering I noticed an issue…
I was dropping simultaneous button inputs like LP+RP or LP+RK, etc. At first I thought it was all in my head, so I continued to use the stick for a few days. Same thing. I then attempted to identify the button(s) at fault and replace them with some other Sanwas I had lying around (previously installed in an HRAP). Same thing. I then replaced ALL the buttons. Same thing. I replaced the Sanwa stick (again with one from my old HRAP) since it does have a PCB of some kind and could be at fault. Same thing.
I then plugged up my old MadCatz and tried using/performing the same characters/moves that seemed to give me the most trouble and found I had no issue at all. I could do the same combo/multi-throw 50 times (literally!) w/o dropping it on my MadCatz but I could not get into double-digits on the eightarc w/o dropping an input (well, maybe “drop” is a bad word; what actually happens is you get LP~RP i.e “button roll” aka “slide” instead of LP+RP, for example). So I decided to perform another modification I had been thinking about doing…
I purchased a Paewang Revolution (Joytron) PCB from etokki.com so the stick would be dual-mod (PS3/Xbox360). I’d then have a “fully-working”, dual-mod stick (“kill two birds with one stone” was the idea). So I had a buddy (who was a recent EE grad and had a temperature-controlled soldering iron, multi-meter, etc) solder it up according to Laugh’s guide here on SRK (linked-to from focusattack.com). Once I installed the Paewang PCB in the stick, it is worth noting that ALL buttons (except the mode, turbo, start, home and select buttons on the side; since they are non-standard 22mm buttons), ALL stick components (including the wiring harness) and ALL electronics (PCB, wiring, etc) had been replaced at this point and guess what… SAME THING!
So I look at it like this: 1) I got two bad PCBs in a row – not probable, but possible 2) There is some kind of explanation involving small electronics (PCBs, USB, etc) or 3) I am just crazy and need to stop whining (or just use the MadCatz stick!).
So to all of the “people in the know” regarding electronics, stick mods, etc. – Toodles, Laugh, etc. – is there an explanation for this other than bad components or general craziness?
