Solomon's Key:
Feng Shui: Using the magic blocks, spell out Dana's name on the field.
Feng Shui 2: Change all magic blocks into air and all air into magic blocks in some room. (I don't know whether this is possible.)
Don Juan: Collect four or more fairies in a single room, bonus rooms excluded. (As far as I know, this is only possible with the acquisition of an extra bell from an enemy.)
Fairy Harem: Collect 50 or more fairies.
Fairy Kingdom: Collect 100 or more fairies. (This also nets you 10 extra lifes.)
Royal Pleasure: Rescue the princess.
Chauvinist: Torch a fairy into dust.
Psychopath: Torch 5 fairies.
Masochist: Die 10 times without a game over. (Does not need to be in a single room.)
Chrono Master: Finish a room with 45000 or more remaining on the timer. (Tweak the number to adjust the difficulty level.)
Savor the Moment: Finish a room with 10 or less remaining on the timer.
Scorched Earth: Cast six or more fireballs (any size) in the same room.
Scribe of Doom: Prepare a scroll with eight fireballs (of any size).
Blowtorch Man: Blow up 6 or more enemies with a single fireball.
Pest Killer: Blow up 7 or more enemies with a single fireball. (Hint: Transmutate orange diamonds to acquire super fireballs.)
Pest Cleanser: Blow up 8 or more enemies with a single fireball. (Hint: Collect many crystals, especially the orange ones, which you can acquire by transmutating a blue diamond thrice.)
Ultimate Exterminator: Blow up 10 or more enemies with a single fireball. (I don't know if this is possible.)
Three of these are accomplished in
the TAS.
Bigfoot:
The Shredder: Disintegrate the opponent's vehicle three or more times in a single race.
Will Not Be Back: Bankrupt Terminator.
Financial Crash: Bankrupt all computer players: The Growler, The Charger, The Crusher, Terminator, The Smasher and The Viper. (I don't know whether this is possible!)
Gyro Gearloose: Climb a mountain (and win) without blowing an engine.
Simon's Quest:
Hacker: Defeat Dracula at day 0, passwords allowed.
Perserverer: Defeat Dracula at day 99, no passwords.
Unholy Priest: Defeat Dracula using the holy water only.
EDIT: I went ahead and created a TAS that beats the third achievement -- that is, defeating Dracula with holy water only. It uses a password. I optimized the password for the time it takes to enter it, with the following traits: required items, 8 garlics, day 0, level 6, smallest whip, some laurels, no other special weapons.

Master of Minimalism: Defeat all four seasons without ever upgrading the shirt colour.
Masochist: Survive a hit from a grenade thrown by the red shinobi.
More Than a Scratch: Get scorched by yōbō (and die). (Trivial, but included to give a hint on the means to achieve the following:)
Just a Scratch: Survive a hit from the yōbō's fire. (This is possible.)
Goonies:
Straight Guy: Defeat the game without using the warp zone.
The Hoarder: Collect all the equipment and all the diamonds.
Arkanoid:
Magic Initiative: Finish a stage by never touching the ball after the launch.
Clean Field: Finish a stage with one ball and nary an enemy in sight.
Ultra Lucky: Collect five 1-ups. Score bonuses don't count.
This TAS achieves one of these (twice). (Or two, if the final boss is counted.)
Gradius:
Faster Than a Lightning: Maximize the speed upgrades.
The current
TAS achieves this.
