Pre-orders are now open for Darksoft’s Neo Geo AES ROM / Flash cart! After shipping, mine came in at around $635, which is far less than many original AES games, but still not what you’d call “cheap”. Overall, if your goal is to play Neo Geo games on original hardware, a ROM cart like this should be considered a “must have” for most people.
You can get yours here and they’ll ship in the order purchased; No skipping the line because you showed interest on a forum, etc, just a fair, straightforward pre-order list: http://www.saveyourgames.it/index.php?route=product/product&path=89&product_id=166
