I wasnt aware of this dev nsp.. is this the same as DevMenu i found on this forum?So to make things more confusing. You may have to reset a game every now and then. I use the dev mode nsp to do this. It kinda gets you back to square one. Sometimes this is needed. If other nsp are working then you may have to reset that specific game.
I did notice in tinfoil (side note), that i have a bunch of "tickets" with no names, not sure if those can just get deleted or maybe thats normal to see blanks?
On the note of the main topic here, i did get both snes and nes working with much fuss. Found a newer version for each and now they seem to run, but not with 500+ roms, just the base set (fine by me).
