I know that there is always the action replay option, which is quite limited considering that there is no read/write feature, (I have the DS lite version, not dsi), but does the Action replay dsi work with putting sav files, editing the sav with Pokesav, then putting it back onto the cart? I also know of the NDS adaptor plus, but it is pretty expensive and only works with 32 bit operating systems, (I have Snow Leopard and Windows 7 professional 64 bit.) I also know that the rudolph homebrew software doesn't work due to the new build and on the HGSS retail carts. But does anyone know of some good cheap alternatives that are relatively straightforward to use and could be used to read/write sav files and dump it onto the cart?
