I've never even seen an MVS or AES, so the Dreamcast versions of NG DEV games were all I ever had an interest in. It seems lately the Dreamcast homebrew scene has exploded. But of all of them, the ones I have most enjoyed playing lately are the NEO GEO games that I otherwise would have never had an opportunity to try. They look and play great on the Dreamcast and are very inexpensive too.
