SNES with strange motherboard

Hello guys, a couple of weeks ago I've decided to take my old SNES (SNS-001) and restore it. It was stored for at least 1 and half year since the last time I tried to play. But this time I wanted to repair the RF port which was malfunctioning for a long long time, kind of corroded (IMG). I then start to search the internet for tutorials, found nice mods to put s-video and composite ports in it, add a lock and 50h/60h switches and replace the fuse (some of then here on racketboy). So I ordered a gamebit tool from amazon (i live in Brazil, kinda hard to find it here), oppened my SNES for the first time ever (i hope so...) and bang, the motherboard inside was different from all the ones that i've seen in the tutorials, it even didn't has the fuse (not on the place it should be at least). So, the question is, anyone has seen this board before? will I be able to make these mods?, or at least there is a way to replace the RF port only, maybe desolder the entire RF block and solder a new port directly in the 4 pins in the board? (i've found that its really hard to just replace the plug). Take a look at the photos:

the motherboard
a closer look
a closer look 2 (some chip with Sony logo in it)
another closer look
the place where the fuse should be
the sticker with model no. on bottom of console

Just to finish, I'm kind of a eletronics newbie (don't know much about chips and circuits). But I'm kinda good in fix things, and I really want to fix that. Thanks anyway

It's a bootleg. I've seen them shared before online at other sites. I think they function as well as it should compared to an original, but it is a fake.

It looks like a lot of solder joints could use resoldering. I see a lot of items where there are holes and bubbles in the solders. Near the Sony chip and marker C29 and the stuff from the bottom of the board near C35 that is close to the heat sink especially.

Cound't this be just some sort of brazilian revision of SNES?

There would still be Nintendo marks on the main chips and somewhere on the board.

Like he said, if it were real the board would say Nintendo as would a chip or two in there too, plus you don't see the Sony branded SPC chip either. It's a fake and when you see the actual system before that kind of tear down it's very hard to know it's one too and are easily passed off for real and many likely would never know the difference or care.

I believe Kkasino maybe is right in something. At the time SNES was released (we never had a console from Nintendo officially released in Brazil) one enterprise named Playtronic (and later, Gradiente) was a representative of Nintendo in Brazil, selling SNES (and the NES too) here. Maybe they where manufacturing another type of board. If you look closer in the board there are pins with "50hz" and "60hz", and also "NTSC and PAL", I dont know if other boards have this points too, but the lack of a fuse and Nintendo branded chips is really strange, the box of the console is entirely in english, and outside its hard to know if its a counterfeit. Anyway, will I mess things up if I desolder the 4 pins holding the RF out, remove it and solder a RCA female jack with wires directly in the board using the same 4 pins? since I do not believe that I can make the s-video and composite video mod while the board is so different. And there is a way to make a kind of "fuse bridge" in one of the power poles to protect the system?

(my english is not so good btw, sry guys)

There's no way you can ask the same question on brazilian message boards/forums?

I'm pretty sure there are experts on NTSC/JPN stuffs here. But mistakes can get costly.

But since your console is quite different. Maybe someone can answer it in your own country? Someone that has already modded theirs?

We dont want to mess up you SNES.

Im curious what does the console shell and box look like.

[lordekeen]

[flojocabron] I will do that for sure, I started here because was my first thought. But even in brazilian forums i didn't see a board like that in tutorials and stuff.

[ninja] I will take some photos of it and post here later. Other people can found usefull to have this thread to look and compare if they have a SNES like that too.
