Play Zone V001 4in1

This romfile comes from a bootleg pcb.Like 39in1 and 48in1 it is an hacked Mame emulator modified to run as coin-op.This version allow to play only the first four games of the list (Ms.Pacman,Galaga,Frogger,Donkey Kong) so i suppose that is one of the first version of it.
Hardware is the same of 39in1 and 48in1.I cannot dump 93c66 eeprom security data and 29c160 flash rom with gfx/fonts/romfiles data since they are in SMD format,but i think that they are the same of other versions (the data of second device surely).
Rom definition:
pzv001-4 main program
93c66-4 decryption data*
eprom is 27c4096

*Update: eeprom data dumped.Decryption is different from 39in1
