Android Marketplace question

[madkoopa]

My father is interested in this tablet for use with his business. There is a specific app that is available on the android market.
I know it is available because I saw it on my android phone.
I also know that this tablet doesnt support the "Google" market. I don't know if that is the same as the android market or what. Either way I doubt this specific app is available for it.
Here is my question:

Will flashing the ROM enable the android marketplace so he can get that app?

Thanks fellahs.
