In our initial program, there are only two interrupts per frame: one mid-screen to prepare for drawing the board and status line, and one at the bottom to reset the display for the logo next frame. This meant that the interrupt handler could decide what to do simply by checking the current scanline as reported by the $D012 register; if the value was over 127, do the end-of-frame work, and otherwise do the mid-frame work. That simple test required only a single instruction, and while the exact value of $D012 might vary, the test was broad enough that it didn’t have to worry about it.
The issue with all-in-one SDKs is that you get a long list of parameters to tune, without really understanding which ones matter or why. When something feels off, it's hard to know where the problem lives. That's what pushed me to go one layer deeper and build the core loop myself.
