Semi OT question

my dad just got a compact flash card, would it be possiable to hack a deivce to allow a cart based system to read data from the compact flash card ?
Assuming you want to run code directly from the CF card, it might be possible if the system you want to use with it has huge read latency on the cartridge interface. In general it's not likely to be feasible, because CF cards are designed to be compatible with hard drive interfaces rather than direct memory interfaces.
