Title: So this AliExpress multicart is 3 volt not 5 volt, right?
Post by: hippy dave on September 08, 2025, 11:33:11 am
Hello  :)

I bought this cart some years ago to use with my Powerjoy famiclone (which I didn't actually end up using much because of the cheap toy vibes). I now have a real AV modded Famicom on the way, and I don't want to damage it after reading the stuff about wrong voltage carts.

You cannot see attachments on this board.

I googled the numbers on the chips, and the flash on the left and the SRAM on the right both come up as 3V. The SMD132 comes up as a mapper for this kind of cart but I didn't see its voltage. I'm assuming tho that it doesn't also double as a voltage level adjustment between the cartridge pins and the other chips.

So I shouldn't use this cart on my precious new Famicom when it arrives, right? Not a disaster but I was looking forward to trying some of the bootleg games, will have to try again looking for dumps.

I probably should have posted the back of the board, but there aren't any components on it.

How would it hurt your Famicom? I think it's more likely to damage the cart possibly, not your FC.

There's technical discussion elsewhere, but it's been concluded at least by some people that it's potentially harmful to the console if the cartridge components use 3v.

No voltage translator in sight, yeah this is likely dangerous to the Famicom. I wouldn't use it at all.

Famicom is a 5 V machine and this cartridge is made for 3 V. Using it with a Famicom would damage both the cartridge and the Famicom.

Figured, thanks for confirmation!
