After a somewhat shaky early launch in Asian territories, the new tiered version of PlayStation Plus arrives in North America today, and it seems like Sony has made some significant improvements to the service. First off, players in Canada and the U.S. will not have to deal with laggy, stuttery 50hz PAL versions of PS1 and PS2 classics – games like Ape Escape have been confirmed to be the proper 60hz NSTC versions.

Confirming myself that Ape Escape is the US NTSC version!! ☺️?
