3-2 and 3-4 were really difficult. Although 3-4 tooks much more time to reach a very satisfied result, It's not final version for me - but TASing a single stage for a long time is stressful.
With some pausing (start button), it's possible to delay that attack from those "guards" on 3-4, avoiding some lags. Actually I did the same with an enemy at the end of 2-1, but avoiding even more lag.
3-3 boss sucks when playing on real time: He has 16 HP, but when he reaches 0 HP, It's still possible to hit before he "dies", but the HP "resets" to 255 - which means that you still must attack until reaches 0 again, or lose a life to restart the battle. Interessingly, this boss has an own HP address.
For 3-5, I managed to hit both bosses as soon as "invicibility stunning" ends, with some help of running, which increases the Y speed a bit more.
