Looks okay. Bootgod has this.

Slotted screw three screw cartridges aren't unheard of. There was a short transition from five to three screws, then later slotted screws to security bit screws in 1987, so a handful of titles had that weird three slotted screws. I have a Zanac cartridge with three slotted screws.

Thanks! That's good to know. Still wonder about the board though. Like I said, it looks professional but has different chips than the pic I found on here. The reference board has Sharp made chips and I looked up the serial numbers and the same chip on mine is by Toshiba


Tulpa drops the facts. Learned me something. And yeah, always check bootgod. 

I would trust SNESNESCUBE, on the chips.

Out of pure curiosity I checked mine and I have one with the slotted (non security) screws. I had no idea until today, haha. Either way... mine does have the Sharp chips... but as I said, I trust those above.  ]]> Help!

many manufacturers made the chips that nintendo used, particularly the chr ram chip, is it is a standard 6264 SRAM chip. The only proprietary chips on there are the PRG ROM and the lockout chip. It looks legit to me as it has the product number engraved into the PRG ROM itself. They also made various revisions of the UNROM boards. I can say with certainty that it is legit. ]]> Help!
