NeoPop PSP is a NeoGeo Pocket emulator for the PSP.
Known issues
There are a number of bugs that are emulation related and will not be fixed unless someone else fixes them. See the official homepage for a list of bugs (including missing audio in Sonic Pocket Adventure). DAC audio playback is currently not implemented. This is most noticeable in the absence of the usual Se-ga! voice at the beginning of the Sonic Pocket Adventure. If enough people are interested, support may be added in the future (it's mostly missing because the emulator is already slow). Enabling the frame limiter seems to slow down the emulation unnecessarily. For now, keep it turned off. Music playback seems to be lagging in comparison to video, this is hard to confirm, since the emulator never reaches 60fps with sound, making it is impossible to test it at full framerate.
