Never assume you can just drop a chip in place of another.

The LH5164AN will most likely have the same pinout as the 5264 found inside of the gameboy itself. You can find it here:

actually, the original pinout came up on my first search;

I do want to criticize your reasoning behind why the MB85R256F is a "good candidate" or not. Having the same number of pins means nothing. After looking at the pinouts,. they are nearly identical after all though your FRAM chip is four times larger in capacity. I say nearly because there are two problems, pin 26 and pin 1. The FRAM has A13 on pin 26 whereas the gameboy has CE2 (high enable) on pin 26.
Pin 26 in the gameboy seems to go to the low power reset chip, so I cannot think of the function off the top of my head.
probing around... The pin seems to be low when on battery power and high when the gameboy is supplying power. I guess it just disables the chip when on battery power. With this in mind...it seems like this pin may be connected straight to the board without having to worry. When it is off, the lower bank of ram will be selected and when it is on, the higher bank will be selected.
As for pin 1, you must bring it high or low, it cannot be left hanging since it is an addressing pin. Either high or low will be fine.

Ahh, like a slide for a microscope. Try clear nail polish. It will harden and keep, but you'll never get it off...

And just so everyone knows, these are the last you'll ever see of Programmers by me. I need to make room for nitro's Altane. If you missed out on the first batch, Kitsch will have the last handful for as long as they last. Two of the above are also claimed, so taht just makes these all the more limited.
What I like most about these now that they have shells is that they no longer tip over with ordinary carts. They also may sit upright if you wish to do so.

Noise is mostly introduced by the power regulators. The newer boys, like PiLs for example, have huge caps on the regulators which very notably reduces noise.

I have just bought a clone arduino. I read that sometimes they can be rubbish in terms of solder pads lifting but I thought I would take the chace as it was so cheap. May regret it but has anyone else any experience using the pro mini or a clone to make an arduinoboy?
is it the same pinout as shown on the diagram on the instructables website?
I have bought clones and had no problems. I am sure there are poorly made ones, but for the most part, the arduino schematics and libraries are all open source to anyone. If some Chinese in-house hbbyist wants to make a load of boards to sell, he still has the same fab houses to order from as you or I do.
I wouldn't worry about the pinout since the gerbers are distributed freely.

I have no idea how to picture this. The thread was posted in Nintendo Handhels, so I' assume' you are working with a gameboy, correct?
What do you have wired up? Is the LCT powered, did you remove the internal clock, did you wire up the LTC to the gamboy yet? Did you read the datasheet? I swear, you make it sound like you are just soldering the potentiometer to random screens in your house.
Anyhow, the gameboy cannot handle nearly half of the frequencies that the LTC can produce, so what have you done with pin 4 on the LTC chip?

Read the datasheet. They always have example schematics.
