smartfp - render something that isn't garbage (once sprites appear) (nw) (#5052)
* better logging (nw) * (nw) * (nw) * sprite drawing improvements (nw) * (nw) * debug stuff (nw) * this changes flow (nw) * prepare for possible palette banking (nw) * log a register value, might be important, might not (nw) * smartfp - push forward (nw) * 'bank' palette writes (nw)
