The "What is the best software for..." thread

For emulators I use the following

Snes - Snes9x 1.53
N64 - PJ64 2.0.0.2
PSX - ePSXe 2.0 (released the other day)
PS2 - PCSX2 1.4.0
GBA - mGBA 0.4 (extremely fast and very very accurate)

For video editing, I use VirtualDub as it's free and has some decent features
For audio, I use Audacity since that too is free, I don't like having to pay
For video capturing, I use nVidia Shadowplay since it has minimal impact on performance, which FRAPS is infamous for

Video player, I use VLC as it supports many formats that Windows Media Player doesn't
These are my choices
