FC 16 Go internal pics -- First Commercial Snes Portable

[Triton]

anybody know what voltage the LED backlight runs at? im guessing ~3.3 but if anybody has concrete info let me know!

The lcd runs at 3.3v but the backlight + line going into the Lcd runs at 18v for some funny reason.

do you know what the current draw is?

[Triton]

double post, does anyone know where on the board the LED backlight is getting 18v? what component supplies that voltage? thanks!

Wow, that's REALLY weird. I'm going to open up my FC Twin and see how I soldered the lockout chip on its Super NES board, as the solder spot is identical minus a spot to solder the 2.2uF capacitor.

EDIT: Hang on, I might have made a mistake on how the capacitor should be soldered. After looking at pictures of the FC Twin Super NES motherboard again(I don't have access to my FC Twin), it seems like the negative pin on the capacitor DOES NOT go to Ground, but somewhere else on the motherboard. Once I get to my FC Twin, I'll tell you where that somewhere is.

Dear Ace, do you find the place that the negative pin of capacitor should connect? I hope to make my FC-16 go to run the game with SA-1 chip. Many thanks.

heres an alternative I found: http://www.mmmonkey.co.uk/console/nintendo/mariorpg.htm

Do I see a solder spot for a Super NES lockout chip? Look at the empty solder spot U9 on the motherboard.

It's exactly like the one on the FC Twin's Super NES board before it got "Made in China" printed on the box and console(the Super NES board was redesigned when Yobo started to put "Made in China" on the box and console, and as such, the solder spot was eliminated). Look at this old picture of the very first FC Twin made before Yobo put their name on it. Right on the bottom right corner of the board, there's an empty solder spot for a Super NES lockout chip taken off a cartridge:

I smell full compatibility on this thing! Get a Super NES lockout from a crappy Sports title, and off you go! Full compatibility with all games, including those with the SA-1 co-processor.

By the way, is that a CXA1145 I see on the top right corner of the FC16 Go's motherboard? If so, I only have this to say: EWW! The original non-Yobo-branded FC Twin had the CXA1145, which resulted in blurry Super NES video output, which would mean the same thing would be the case on the FC16 Go. I thought Yobo ditched the CXA1145 in favor of the superior CXA1645 found in their jeweled FC Twin and the FC3 Plus. What's a CXA1145 doing in the FC16 Go in that case?

Do you know any cheap game I could get to get a lockout chip from?

actually there is a cheaper way, mod the cartrage, and add a PAL switch. the PAL switch changest from 50Hz to 60Hz while the cartrage mod makes the few games that actually need a lockout chip (the only real notable ones being Mario RPG and Kirby Super Star) you have perfect compatability (although you will need to apply the mod to each cartrage individually) heres a link to the cartrage mod: http://www.mmmonkey.co.uk/console/nintendo/mariorpg.htm

So correct me if im wrong but can the snes board be used without the video/controller board? If yes than does any one have a pinout for the two white cable connectors on the board?

Not yet. My FC Twin is dead now(NES board has no more sound and all I get out of the Super NES board is a bunch of gray lines. I'd need to try using the FC Twin's RGB to know for sure if the Super NES side is truly dead), so I'm gonna remove the lockout chip and capacitor and retrace all the connection points for the lockout chip and for the capacitor.

Any crappy Sports game you can come across(they're EVERYWHERE).

Since all the chips of the FC16 Go are on a single PCB, you can just use the motherboard without anything else. However, I don't have an FC16 Go, so I can't give you the pinouts of the white connectors, but I'm pretty sure they're labeled on the PCB.

I'm really tempted to pick up an FC16 Go to try and repair my dead FC Twin if the Super NES board is completely dead, but I'd prefer if someone with a faulty FC16 Go(bad screen, broken on-board controls, etc.) would be willing to get rid of it. I don't want to gut a working FC16 Go to fix something already broken.

i've tried to move those jumpers other side (without lockout chip - it's might be removed from cart) but video output became black&white..(but yoshi's island pal i can play now) maybe i've made something wrong? or it just needs a chip?

Black and white picture happens because the unit switched over from NTSC color encoding at 3.58MHz color subcarrier frequency, with 525 lines at 59.97 (60) fields per second interlaced on the screen, to PAL colour encoding at 4.43MHz colour subcarrier frequency, with 625 lines at 50 fields per second, and the screen electronics cannot interpret the PAL subcarrier (so no colour) but can display the raw line structure (the black and white part of the picture).

This also happens when you put an "NTSC" (sic) region free DVD into a UK DVD player and set the DVD player to NTSC 3.58MHz output and feed it into a UK TV that cannot decode NTSC color subcarrier (some can, some can't).

BTW does anyone know if there is a commercial SNES portable on the market with a 5" (or approx.) screen or larger? I find the 3.5 inch screens to be rather small, especially compared to the 45" diagonal that I am used to on my video projector LOL.

Also has anyone made a home made SNES portable with an ORIGINAL SNES model SNS001 PCB ? I would like to have the exact "characteristics" of it in a portable. Or has anyone ever compared the audio from the mini-SNES SNS101 and the SNS001 in e.g. Zelda A Link To The Past? If so, what's the audio quality like on the mini-SNES? What is the audio quality like on the FC16 1 or 2 compared to an original SNS001 SNES?

Basically I don't like emulators or "compatible" units, I want the original, just portablized with 5" screen (or a little larger!). Because of this (and the FC16 screen being too small for my taste) I am going to attempt to make a portable SNES with 5" screen but if I can't use the SNS001 then I'll have to use a mini SNES, but they are expensive for me to get hold of since I am in UK and I need an NTSC unit and an NTSC PSOne screen (also expensive), since PAL games play at the wrong speed and with a border and I have an original NTSC SNES and NTSC Zelda ALTTP...
