a solution to that problem could be the use of a FPGA chip interface
CF -> FPGA -> gp32's SMC connector
FPGA : is a programmable chip, which is perfect for that type of application :)
For the datasheet of the GP32 proc, just do a search in the samsung's site. They don't give direct access as they for the newer proc, but the datasheet is still on line with some other stuff. I didn't know that the proc have hardware scrolling implemented (c siper) !!!!
