Cool combo NES/SNES clone I found.

Cool combo NES/SNES clone I found. 56k

It's a 2 in 1 NES/SNES clone that's about the size of a mini-SNES called the FC Twin. The best part? American cart slot, meaning NO MORE CONVERTER! It also takes original SNES controllers and special accessories, such as the Baseball bat for Super Batter Up (it actually works pretty well). Worst part? I'm pretty sure the NES is a NOAC and it doesn't take standard NES controllers, meaning no Duck Hunt or any other Zapper games. Anyways, on with the pics!

I like the box.

All neatly packed.

Playing Super GB and Bible Adventures (who knew a 600 year old man could run so fast with 5 animals on his head).

Guts of the system, pretty well put together if you ask me.

I got my Gamebit today.
Anyways, this thing set me back $60.

 

does have s-video and rgb ????

 

More importantly how's the SNES? Cloned? If so, doesn't the SPC suck like the GameStation? Same with the PPU.

Still a neat find.

 

sexy

 

interesting I think the clones are coming

 

does it use *a* compatibility mode of the 65c?

I know that nintendo originally wanted backward compatibility between the NES and the SNES, but that was later on dropped all together. The SNES processor has a complete backward binary compatibility mode , compatible with the NES processor. Beyond that however, audio, memory, and video are handled quite differently.

 

It clearly uses a "NOAC" and XGA "SNES2" ASICs, quality will be poor on both consoles. No it does not have RGB for FC (of course) and it probably doesn't have RGB for SFC either just like the SFC/SNES Jr, it probably does however have S-video for SFC though but not for FC (of course).

Also the 5A22 is not directly compatible with the 2A03 as it doesn't have the APU core nor is it backwards compatible with the NMOS 6502; it's only backwards compatible with the 65C02.

 

Nope, no S-video or RGB. Luckily you can still use standard AV cables.

 

Awesome find. I'm with Motzilla here. How does the SPC clone sound?

 

It sounds fine to me.

 

Did you test FF3 though on it? I'd imagine things like that whistling effect might not sound the same if the SPC cloen isn't good enough. I remember one of the NOAC things I had, the sound was pretty badly off in some games. One of the Super Marios.

 

I don't have FF3. SMB sounds fine though.

 

Good. Another test of the SPC would be Chrono Trigger. If you have that, that'll show you good differences if the sound is off.

Zelda would work too.

 

Judging by the picture the SPC looks original, does it have Nintendo written on it?

 

I'll check.
EDIT: Nope, but it's definantly not a SOAC.

 

It should be quite possible to get RGB off it - the SNES portion uses a Sony CXA1145M rgb encoder, so you could just tap into the RGB inputs. This chip should be right below the DC input jack. You'll have to unscrew the heatsink.

Datasheet:
http://pdf1.alldatasheet.com/datasheet-pdf/view/77344/SONY/CXA1145M.html

Pins 2, 3, 4 are RGB respectively and 10 or 11 are both composite sync.

This only applies to the SNES portion though. The video generation circuitry for the NES is built into the NOAC glop-top.

As for other NES controllers, they should work fine if you can re-wire the connectors. the SNES controller just has a second latch for the extra buttons while NES controllers only have one.
Worth a try, anyway.

 

I'm tempted to try this, but what's the chance of killing the machine?

 

Unless you botch the soldering and spray solder on everything (pretty hard) you won't break anything. If you've never soldered onto surface-mount chips, you might want to practice first.

I'd also grab some solder wick/copper desoldering braid at RatShack or equivalent to soak up solder when you bridge the pins on the chip.

 

sorry to pop this up again, but what is a NOAC?

also, does the NES work with Maniac Mansion and Castlevania 3?
the same with SNES and Super Mario RPG, Starfox, and the Megaman Xs (didnt they have special chips, too?)
Thanks

 

NOAC means Nintendo On A Chip Basically one chip that includes an entire NES console. I could think of far better things that NOAC could standfor though.
