Getting Started

You will need to download the programs you will use. They are:

First of all, you need a Mega Drive\Genesis emulator that supports VGM logging. So far, only Kega Fusion for PC can log VGM files correctly (Gens has timing issues, so it should not be used). Sadly, there isn't any accurate emus for *nix/Mac that can do this yet. Download Kega Fusion.
You will need Winamp full version, which includes the disk writer plugin, in order to create the wave files from the VGMs. Download Winamp Full.
You will also need the Winamp plugin to play VGMs. Download the VGM Plugin.
You will need the latest VGM Tool in order to trim and tag files. Download VGM Tool.
You will need a sound editor in order to find trim and loop points. Two popular ones are GoldWave (shareware) and Audacity (freeware). This tutorial will use GoldWave on its examples, but things should work about the same with any other program.
In order to properly optimise files, you will need to have OptVGM. This is the last thing you'll ever do with the VGM files, so you might want to think about it later.

Once you know you have these ready, proceed to the next step, the logging.
