On the regular Famicom the controllers are not soldered in on the console side but connect to a header. If that's the case for the Twin Famicom as well you could make an extension cable for that. I personally would just leave the console untouched and use the extension port with a regular external Famicom controller. IIRC they're just regular DB-15 and a Neo Geo controller extension cable might work if they're still too short for you. If you need two controllers you can also get Famicom->2x NES adapters and use any pair of NES controllers with it.
thanks for your input. your solution is what i wrote above which is just cut the cable and extend it.
i know the expansion port but i really want to use the original controllers... i only need 20-30 cm, not much since I am sitting nearby... heck even mere 10 cm could do it but 20 cm would be perfect.
what i had in mine is to use a small solder board like this one: https://imgur.com/ZEZJhNv
where i solder each wire from both sides to the same point then make them all covered with capton tape then a heatshrink. one per each controller would be fine.
i saw this product: https://www.gamedoctorhk.com/index.php? ... ts_id=2027
but not sure if i would need it and there are 2 versions of it. i don't understand from the picture how should it be used + out of stock.
