Neo Geo Poket Flash Cart Homebrew?

I was wondering if nayone had found any info on how to build neo geo flast carts. I know you ca flash the commercial games and the flash carts exist so there has to be a way to make a homebrew right?

Here's an NGP flash cartridge schematic, courtesy of the insanely great Gamestation X. This doesn't handle flashing, but you could conceivably use it in conjunction with a programmer and homebrew slot adapter. I don't know what kind of flash chip that is, but its interface doesn't look particularly exotic.
