Left is an early pack-in version of Super Mario World. Nothing about it looks fake. The ROM chips and micro controllers look accurate for the time period, so does the yellow battery. The one on the right is clearly a later release of Super Mario World. Slightly different PCB, copywright from 1993, also the cart uses the concave SNES carts, which are legitimate and something that Nintendo switched to around 1992-1993. If you ask me, neither of these look fake. It is much harder to source ROM chips like those in this day in age. They both do look real, but were manufactured at different times. With the one on the left being the older cartridge; 1991 - 1992.
