Default Custom roms and ISIS

Hi All,

I'm using the isis mobile wallet because right now you get $50 loaded on your pre-paid card when you sign up for free. Is there a way to make ISIS download from the marketplace when on other roms that are not TW roms? When I go to the marketplace it does not allow me to download saying it's not compatable with my device. Normally I am using google wallet, but in my market, there is a lot of deals that pertain to me on ISIS.

Thanks!
