For number 4, instead of winkawas I would suggest Callus95
since winkawas only lets you have 2 lives and if you die you have to restart the game all over.
However Callus95 runs some games sideways such as 1942 and those are hard not to play so download Nebula
which should play those games the right side up.
Since however nebula can make those games quite choppy I would suggest to adjust some of the settings such as no frameskip and etc. but if you still are dissatisfied with the play and don't like jerking your head 90 degrees to your right I would suggest to look for another good emulator from the net. A list of emulators can be found here which let's you download some:http://emustatus.rainemu.com/emu.htm
Also for the NES emulator try dling bioNES since it has better and the original sound and some games on it work that they don't on Nesticle, but some work only on Nesticle so try to have both.
