SNES reproduction cart. big project

[Jittabug]

Hi every one I'm new to forums and this is a first for me so I hope my subject don't offend anybody, as SNES reproduction carts seems to be taboo with retro gaming.

so as a project I wanted to make 2 reproduction carts Captain Commando and Fatal Fury Special. There is a twist I wanted to use M29W640TF TSOP. Why this flash? I have a SD/SNES flash cart China Version and it uses that chip.
Also there's a Captain Commando boot leg on Ebay that uses 29LV160ABTC chip I think both chips are miles apart but I cant find a data sheet for the 29LV160ABTC.

There must be a SNES god out there that can help me!

I have abused Google so this is the end of the road. Both games use SHVC-1J0N-20 and are basic no SRAM or Battery.

So, if you have a SNES cart that you can copy a ROM onto (via SD card), why bother?
