Masterbase conversion

You know, I've never really looked into that.
If it's plain text, then sure, but I'm afraid the data is stored in binary form and someone (me?) would have to do the analysis on it first.

OPT does have it's own cards / sets files though, they are created using gatherer and updated via the client.
They contain cards from all the sets defined in the sets file, but some people also want promo cards and whatnot to be in there and I do not currently provide that support.

Further more, the mtg.cards file can be opened with notepad++ so you can see how the data per card is stored.
Same for mtg.sets.
