Got a new zero key from mitsu and played around with my old netdimm for a while. Still seems flaky, but the zero key works. I used transfergame.exe to test. I like how that gives you a status as it loads. so my other zero key was definitely bad. I still have an issue where a game will sometimes load a bit then fail. Then I just have to try again. What usually works is if I go to test and clear backup data, see if I can ping the netdimm and if I can try from there. Sometimes I can’t seem to ping it but resetting gets it back to “checking network” and I can usually ping it then. So this netdimm seems to work but it’s a bit of a pain. The other one I got recently works great and I just got a cf kit for another regular dimm from mitsu. So with 3 ways to boot any game I figure I’ll be covered when some of this stuff inevitably gives me more issues later.
