For those who have the PS2 Darkstalkers Collection, I recently attempted to translate what seems to be the most thorough documentation of the Secret Option dipswitches as seen at Shu’s Darkstalkers Frame Data site. The description refers to the effect when the switch is on (star is filled). They’re numbered by row, then column. Keep in mind that my Japanese isn’t perfect and that I don’t have full understanding of some of the effects, so they might not be 100% accurate; they should be in the right ballpark, though. I’ll continue to update this post as I come across more information and clarifications.
VAMPIRE
[LIST]
[]1-1: Demitri’s Bat Spin can’t be continued by repeatedly inputting the command.
[]1-2: Aulbath’s crouching hard punch is an overhead.
[]1-3: Startup of Morrigan’s Darkness Illusion is unblockable at point blank range.
[]1-4: Unknown.
[]1-5: Whiffing a Mega Spike causes Victor to become unable to perform specials. (? Haven’t verified this yet.)
[]1-6: Glitch which causes P1 Demitri to remain invisible if he is grabbed during Bat Spin startup by P2 Demitri’s Midnight Pleasure.
[]1-7: Phobos is hittable during his mid-air chopped in half animation (such as caused by Bishmon’s Oni Kubi Hineri).
[]1-8: Anakaris’s jumping light punch glitch: When it hits at a certain range/angle, the opponent behaves oddly (as if they had blocked), and the hit is counted as comboed into whatever attack hits next.
[]1-9: Anakaris Pharaoh Magic glitches: If a successful Pharaoh Magic is interrupted, then the hits that were made up until the interruption will count as being comboed into whatever hits next. Also, if he is interrupted while the opponent is frozen by the ice hit, they will remain frozen until he hits them with something.
[]1-10: If an opponent in a hittable midair knockdown state is hit just as they reach the ground, they’ll transition into a ground hitstun state (similar to SF3 Gill).
[]1-11: Arcade version credit roll.
[]1-12: If Phobos is hit during crouching hitstun, he’ll transition to standing hitstun (same as SF2 Honda and Blanka).
[]1-13: Unknown.
[]1-14: Chain combos become Hunter style (punch-to-kick is possible, and input is more lenient).
[]1-15: Whiffed moves can be canceled.
[]1-16: Player 1 has an advantage on air throws.
[]2-1: Input recognition becomes more lenient (similar to later games in the series).
[]2-2: Auto-guard is selectable.

Phenomena that cannot be changed via options (the same no matter whether all stars are on or off).
[LIST]
[]Ability to change the hitstun length of a jumping light attack by pressing a medium or hard button the instant that it hits.
[]Demitri, Aulbath and Zabel are able to crossup cornered Victor, Sasquatch and Phobos.
[]Jumping attacks with long active periods (jumping light punches and such) are capable of being blocked in midair then hitting again if the opponent lands while the attack is still active.
[]Once Gallon, Zabel, Morrigan or Aulbath block an attack in midair, they are unable to midair block any subsequent attacks that aren’t part of the same blockstring.
[]If Morrigan is hit during one of her crouching attacks, she goes into standing hitstun.
[]Aulbath can cancel an attack into backdash, then cancel the startup of that backdash into a forward dash.
[]Phobos’s Might Launcher can be unblockable. (Note: Don’t know how this is done…)
[]If Phobos is hit during his crouching turn around animation, he goes into standing hitstun.
[/LIST]
VAMPIRE HUNTER
[LIST]
[]1-1: Arcade version credit roll.
[]1-2: Phobos glitches: 1. If you hit a midair opponent with Confusioner just before losing by time out, the opponent will do their winpose in midair. This works even if you trade an attack with the opponent. 2. If you hit a Conusioner-affected opponent with ES Genocide Vulcan, the whole attack will hit even if the Confusioner effect runs out mid-attack. 3. Similar to the last point, ES Circuit Scrapper can’t be escaped partway through by having Confusioner effect run out.
[]1-3: Gallon’s ES Wild Circular uses up all his remaining gauge stocks.
[]1-4: Felicia’s ES Hell Cat uses up all her remaining gauge stocks.
[]1-5: Bishamon’s ES Kirisute Gomen uses up none of his gauge stocks.
[]1-6: Aulbath’s ES Crystal Lancer uses up all of his remaining gauge stocks.
[]1-7: Aulbath’s ES Sky Neptune uses up all of his remaining gauge stocks.
[]1-8: Pyron’s ES Planet Burning uses up all of his remaining gauge stocks.
[]1-9: Aulbath can perform a pursuit attack while the opponent is getting hit by Sea Rage.
[]1-10: Lei-Lei can dash and perform attacks during spinning fall state (as caused by Aulbath’s Aqua Spread, Phobos’s Circuit Scrapper, and Lei-Lei’s Houtengeki).
[]1-11: Phobo’s jumping medium punch causes knockdown.
[]1-12: Phobos is hittable during his mid-air chopped in half animation (such as caused by Bishmon’s Oni Kubi Hineri).
[]1-13: Lei-Lei can warp by inputting left->right in 2 frames.
[]1-14: Unknown.
[]1-15: If Victor is thrown during Great Gerdeheim’s startup, its effect will persist until the end of the round.

[]2-1: Felicia is hittable during burned animation caused by a multi-hit burn attack.
[]2-2 Bishamon can perform Tsuji Hayate and Kaeshi Ha even if Hane Ha is blocked.
[]2-3: Unknown.
[]2-4: Felcia’s Please Help Me Glitch: If Felicia is hit before Lucy makes contact with the opponent, then attempts Please Help Me again, the first Lucy will regain the ability to hit the opponent, and if she does the number of hits will increase and the dust clouds won’t disappear.
[]2-5: Gallon has invincibility during the recovery of his far-range standing medium punch.
[]2-6: Anakaris Pharaoh Magic glitches: If a successful Pharaoh Magic is interrupted, then the hits that were made up until the interruption will count as being comboed into whatever hits next. Also, if he is interrupted while the opponent is frozen by the ice hit, they will remain frozen until he hits them with something.
[]2-7: Canceling into Sasquatch’s Big Eisbahn from his standing medium punch causes the ice to appear instantly.
[]2-8: Unknown.
[]2-9: Glitch that causes ES projectiles to temporarily freeze in place. (This is apparently done by having an ES Projectile come into contact with the opponent at the exact instant it should be canceled out by another ES projectile that is pushing against it. The projectile will freeze in place, unable to hit, for a short time then automatically start to move again while regaining its ability to hit.)
[]2-10: Glitch which causes P1 Demitri to remain invisible if he is grabbed during Bat Spin startup by P2 Demitri’s Midnight Pleasure.
[]2-11: The very end of Donovan’s Change Immortal automatically causes the opponent to midair block.
[]2-12: Unknown.
[]2-13: Glitches with Donovan’s dash moves: When he has the sword, during a dash his standing punches behave as if he didn’t have the sword when performed at close range. When he doesn’t have the sword, during a dash his standing punches behave as if he did have the sword if performed at long range. His light kick is also uncancelable during a dash.
[]2-14: Sasquatch’s ES Big Snow can only be performed with LP + MP.
[]2-15: Zabel’s ES Death Hurricane can only be performed with LK + MK or KKK.
[]2-16: Unknown.
[]3-1: If Anakaris tries to use ES Kotodama Kaeshi (Spit) after swallowing Lei-Lei’s Ankihou, it will come out as a regular light Ankihou but still use up a gauge stock. (If this star is turned off, he can’t perform ES Kotodama Kaeshi (Spit) at all after swallowing Lei-Lei’s Ankihou.)
[]3-2: Unknown.
[]3-3: Player 1 has an advantage on air throws.
[]3-4: Dash input becomes more lenient.
[]3-5: Specials/EXs can be cancelled into from chain combos.
[]3-6: Auto-guard becomes Savior-style (No limit on number of times, No auto-chaining, chip damage is received on auto-guard).
[]3-7: Chain combos can be performed in midair.
[]3-8: Chain combos can be performed during air dashes.
[]3-9: Anakaris’s Hitsuji no Mai only comes out on button press or release (can’t be performed by holding buttons down).
[]3-10: Once he has charged back, as long as he holds a forward direction (down-forward and up-forward count) Bishamon can perform ES Iai Giri (similar to SSF2T Honda and Chun-Li).
