The homebrew scene is swarming all over the release of RacePSP like flies on … well, you get the point. It's a Neo Geo Pocket emulator that doesn't yet have some of the features that diehard fans of the homebrew scene currently enjoy with most emulators (things like savestate support, for example). However, it's important to remember that this is only the initial release of RacePSP and the author fully plans to upgrade the emulator. Most people are having little to no problems but the author, Flavor, would like to add that users might experience graphical and/ or sound bugs. RacePSP runs both Neo Geo Pocket games as well as Neo Geo Pocket Color. This is certainly one of the emulators to watch for in the future. You may see this emulator released under the name, "Rather a Cardfighter Emulator", which, if you noticed the bold letters, is simply the full name of the emulator.
