Let's retrace your steps then. What did you change in 1.5? 1.75?
From the changelogs:
Version 1.5:
+Replaced jab finisher with another claw swipe, which is more effective;
+All tail blade sweetspots and Neutral B firebreath now deal extra shield damage;
+Increased damage and knockback on Down Smash and now it can hit behind Ridley twice;
-But range was decreased and end lag increased;
+Slightly increased damage, range and knockback on Side Smash;
+Increased knockback on Glide Attack;
+Slightly increased knockback on Side Tilt's sweetspot and now it can be angled up and down;
-But range was decreased and end lag increased;
+Signifficantly increased Down B Super Armor tolerance;
+Slightly buffed air jumps;
+Increased damage and knockback on Neutral B fireballs, now slightly stronger than Samus' Super Missiles;
-But Neutral B's start up was increased and fireballs' speed was decreased by 1/3rd;
+Instead of glide activation, aerial Side B is now a quick dash forward with damage and knockback close to Ganondorf's ground Down B, giving Ridley a quite effective finisher in the air;
+Increased range on FAir;
+Now DTilt has Off The Ground/OTG properties
-Slightly decreased knockback and damage and increased end lag on BAir;
-Increased end lag on UAir;
-Now glide is activated by holding B button during aerial Side B's start up, which increases its start up;
-Decreased damage on fireballs;
-Decreased knockback on Side B;
-Glide's speed reduced by 35%;
-Increased end lag on Side Tilt;
-All tail sourspots now always deal 3% damage;
-Slightly reduced grab range;
-Decreased max first jump height;
*Decreased volume on special Down Taunt;
*Improved gloss effect on model;
*Improved How to Install instructions;
*Fixed double grab bug;
*Added common5.pac and RSBE01.gct files with codes and CSPs pre-installed for those who can't do that by themselves;
*Added 3 new sound replacements - Metroid Prime Meta Ridley, Omega Ridley and SSBB Ridley voices;
*Now Ridley is a lot darker while under Down B's effect to better match the source;
*Increased time Ridley spends with Metroid capsule during one of victory animations
*All SSE attributes set to match defaul attributes with only few things buffed;
*Added ladder animations and fixed trophy stand throw state, so, now Ridley is compatible with PM's SSE with only few weird things like wrong name, wrong CSS icon and not being present in cutscenes (for obvious reasons);
*Fixed few animations and added extra GFX to few animations.
Version 1.75:
-Decreased knockback on BAir;
-Slightly decreased running speed;
-Slightly decreased damage and knockback on fireballs;
*Fixed game crashing/freezing glitch that happened when you left the match anyhow or it ended anyhow (HAHA, as if);
*Added updated RSBE01.gct file that does not messes up costumes or special team colors for characters like Dr.Mario, Ganondorf, Link, etc;
*Ridley no longer freezes in the air during Down B if platform below him disappears.
