projects going bad

Hi all,

I hope someone can help because I'm going mad here trying to figure it out!

I'm trying to work out how it'd be best to put together a SD memory device which plugs into a game console's cartridge slot and allows loading of games to the console.

I've made up a design flow which seems ok to me but I'm no expert (by far) on this sort of thing, maybe someone can help me out?

Here's how I see this working:



Now I've never programmed more than simple gravity code in Blitzmax so I'm an utter beginner and VHDL and Verilog have me pulling my hair out, can anyone help out here (in plain English) as I really would like to do this but am very lost :(

I know it'd be best to impliment the SD memory card in SPI mode from what I've read.

I hope my flow diagram isn't too confusing, sorry for the huge image!!

Joel

As a side note, is an FPGA even needed here or would a microcontroller be a better idea? :|

The flowchart is nice but what specific problems or errors are you running into?
