I REALLY suggest using the original Metroid II. It is a rule or something.
- If you use a source port of the game, make sure it looks as closely to the original game as possible. No high-definition texture pack, no new 3D enemy models, no unofficial mods. This is all about being faithful to the original, NOT about looking as good as possible.
Then again, the game was already done. =/
I believe commentary isn't allowed. Well, it is sorta allowed, but only if it is optional.
- Don't add audio commentaries, unless you make them optional (as a second audio track). This is no "Let's Play" series.
If I was processing, I would go for the non-commentary version.
Oh, and Tarosan called Final Fantasy Adventure.
