Quick question

[M. Lucanius]

Alright, please bear with my ignorance (I am learning slowly), but I was wondering how possible it would be to do something. I've already been triggering interrupts at hblank, but I noticed that in order for the changes made to sprites in one such interrupt to take effect, the OAM must also be updated every change. After discovering this I couldn't help but wonder if it was possible to interrupt the OAM update between sprites. Is this at all possible?
