The porn industry continues to take advantage of the new media gold mine on the PSP. Production companies GLAYZ and h.m.p. have released a total of four adult UMD’s while Sony looked on in disapproval (which is odd considering Sony is the only company with UMD producing capabilities.) The GLAYZ discs are priced at 3,800 yen and are Japan-only region coding while the h.m.p. ones are all region and around 2,000 yen.
