While SuperCard is the planet's closest cousin to HyperCard that runs natively on the newest Intel-based Macs under OS X, all but the simplest of converted stacks will require a little bit of tweaking to run in SuperCard without errors.
And while the changes that need to be made will be a simple matter for the stack's author, we understand that many folks need to convert stacks they are using that have been created by others. Our HyperCard Conversion Concierge Service offers start-to-finish conversion of your HyperCard stack to a SuperCard project for as little as $85.00.
