Megaman ZX was actually the first one that didn't actually work for the G6 in a very very very long time. Even though, they released an update the day after to fix it. They will continue to release fixes for their products as long as they gain money from their products. Which I anticipate will be a very long time. By the time they actually stop with the G6/M3 support, im 100% sure that all games will work perfectly.
EDIT: The prepatched ver of mario hoops I mentioned is very buggy, so I suggest you wait till G6 releases a new loader to fix it instead.
