4-1 action replay

I just read that some games require the 1mb ram cart and isnt the action replay only 4mb? i also heard something about an action replay where you can switch from 1 to 4 whenever you feel like. The thing is I just got metal slug and im wondering what i should do, since it is a backup and im pretty sure jap. also how to find out which has the switch

The AR4M+ auto switches between 1MB and 4MB.

Other carts like the Saturn Booster Pack have a switch.

Beware though, not all Action Replays are both 1MB and 4MB.

Some are only 1MB.
