I'm going to get an R4, 1GB SD Card ( any suggestions on which brand? ), and a crimson & black DS. Now, I have a few questions that I would like clarified - Will the R4 work with Windows 2000? - Is it really simple to do? - Are the new kernels necessary? ( What is a kernel anyways? ) - If I wanted the Castlevania game to work, what MicroSD card do I get? - How exactly do the saves work? - How does the organizing work? - What are some essential programs I will need to make my whole experience easier? Thanks for all the help, and if any more questions arise I will ask them here.
