Batman NES full playthrough

My first time beating Batman on the NES using the keyboard, not an easy feat for me, thus a rather clumsy play (sometimes the button key presses weren't happening or delayed), but I got through it. So I played this on Mesen (my first time using it actually) and even though it felt better than other NES emulators I've tried over the years, emulator play has never been as precise as the original hardware, and a controller offers better control over the character on screen, but you make do with what you got. This one has always been a strong favorite of mine, easy to play but still tough with the precision jumps and wall jumps you have to make, the last stage usually being the one that takes lives, that at times I can play most of the game well, but then die once or twice there if out of practice, and I certainly was this game, plus the whole keyboard not as easy to use as an NES controller. Whether I continue to play more old games like this, I'm not sure, but for now was a divergence, a break from the usual few games I've played all too much.
