- I'd like to request to someone else with a devkit to run the following test in the NES.
1. boot up (around 1 second)
2. SEI to prevent IRQs to trip
3. select apu mode 0 (4 steps) by writting to 4017h.
4. wait a few frames (around 1 second too)
5. select apu mode 1 (5 steps) by writting to 4017h.
6. wait a few frames (around 1 second too)
7. CLI to allow IRQs to trip
8. check if an IRQ was triggered and print the result.
- Please, let me know the results. I would thank you a lot. ^_^;;
