El autor del NEOGEO CDZ no para, ahora va a por la version de cartuchos, en pspnews han traducido el readme:
Only supporting the compressed ROM set for MAME 0.106.
Clone set containing home purpose ROM is not supported.
Protected/encrypted ROM set is not supported.
Games with special input port or dip switch are not supported.
Due to the lack of memory on the PSP, only the ROM sets smaller 128Mbit (16MB) are supported. (I haven't tested the upper limit of the supported ROM size).
There may still be some ROM sets that cannot be started even they comply with the conditions above.Info from Read Me.
