Is the famicom-to-NES adapter reversible?

[aha2940]

Hi!

So, I have an adapter for using NES games on a Famicom (I think that's 72-to-60 pin adapters). Can this board be reversed (Used to play Famicom games on an NES)? This is from apurely electrical point of view, ignore the physical/mechanical constraints (having to solder/desolder edge card connectos, etc.)

Thanks!

Edit: I got the idea from this video: http://www.youtube.com/watch?feature=endscreen&v=qK6I95SPbUs&NR=1 at 5:15 the guy seems to have soldered an NES to Famicom adapter, but it's using it the other way aorund (toplay Famicom games on the NES). Am I wrong?

what part of http://wiki.nesdev.com/w/index.php/Cartridge_connector don't you understand?

OK, so your rude answer seems to have been useful and guided me the right way. From what I understand in this page: http://nesdev.com/NES_ADAPTER.txt, all the converter does is route one signal in the 60 pin ide to its equivalent signal to the 72 pin side and that works both ways. However that does mean that the NES lockout chip must be disabled in the console, or you should put your own lockout chip in the adapter itself, right? I also do not understand why pin 37 (System Clock) is not connected to anything in the Famicom...

THanks!

yep, it's right

just guess why do nes-to-famicom and famicom-to-nes flawlessly working adapters exist

OK, so it's no needed, but I wonder why is not needed? system clock sounds like the signal which makes everything tick, to me it seems strange that the NES has it (if it has it I assume it's because it needs it) and the famicom not, but then again I'm clearly not an electronics guru.

Regards.

P.S: I liked your other avatar more, famifan

Frankly speaking the game cartridge is just the ROM with some on-board logic to bypass 64k limited i/o space of 6502. Sometimes plus accidentally placed sound expansion chip.

I know only one thing that could probably use the system clock signal http://nintendoage.com/forum/messageview.cfm?StartRow=1&catid=6&threadid=32896 not sure if it really uses it.

system clock is needed for the weird hardware which works on top of the system for synchronization with the enslaved system

another examples are 'virtua racing' for sega mega drive and games with 'super fx' chip for snes/sfc
