V20.7

• Input Display was showing in chunks instead of real time, same thing for damage and hitstun scaling, these now run in real time
  • Forgot to add a freeze guard for all the new stuff, locally everything ran fine, but when exported to a GUI a child process would call the launcher into a new GUI, which itself would call another one, this has been fixed, it's funny because I had this exact error a while back and forgot to keep up with it

V20.6 PTX IIS HERE!!!!

• PTX is selectable on the Character select screen under "Extra Characters", just PTX for now, Lightan should get his time in the sun soon

V20.6.1

• And lightan gets to shine on

V20.5.8 Hitstun Scaling

• Added a monitor for hitstun scaling

• 20.5.8.1: Post KO now works for everyone including Zero and Frank. I think, it seems to not work first match on rare occasions? Will need feeback for that

V20.5.7 Ruler Envelope

-When Ruler Horizontal and Verical are on, a colision "range" is produced, for more accurate collision checking

V20.5.6 Mission mode and ruler fixes

• Took a small break but I'm back
• Mission mode accepts jump cancels better
• Ruler had a distance bug for collision checking, this is better

V20.5.5 Memory Management and health update

• Things are getting bloated, a lot of allocating and chunking and other computer sciency terms are afoot, the program should run smooth as butter until later when I get lazy and let it go bad again

• On the other hand I found better signifiers for meter and health, so the HUD now displays them better

• The hud also has a CORE mode, which is just essentials, research which turns on a few more modules, and Full for those of you who want every piece of info all at once

  • v.20.5.5.1

    • Some mission mode fixes, everything should be cool, also a few bonus missions added

  • v.20.5.5.2

    • Turns out mission mode was the exact opposite of fixed, it's been rewritten to be the amount of fixed I'm comfortable with

V20.5.1 Damage Scaling update

• Damage Scaling is found.

V.20.5 Baroque Flag

• Baroque gate being investigated

V20.4: Protection Tracking and Fixes

July 24, 2026

Counters, armor, and invincibility got an upgrade, as did projectiles and supers in the frame gui

....may need some more work but it's going

The GUI should now show "strengths" of projectiles like Zero's charged blaster or volnutt charge

General cleanup and stability fixes

kthx bye

V20.3: Projectile Hitbox Accuracy

Projectile Hitboxes are updated to be much more accurate

Note I didn't say pretty I just said accurate

V20.2: Custom Cancel lab

You can now batch edit moves to have custom cancels

V20.1: Main GUI update

Main GUI updated to better mesh with the overlay

V20: Punish Trainer and Native Action Mapping

July 15, 2026

V20 introduces the new Punish Trainer.

Select a live fighter slot, choose one of that character's mapped moves, and have the game perform it automatically so you can practice recognizing and punishing it.

This feature came after finding a new static recompilation research path that exposed the game's real action-request and transition systems. Moves are now requested through the game's own action pipeline

V20 ^

v19.2.1: Mission Mode Uniform Updates

All missions have been updated and named

v19.2 Mission Mode upgrade

Mission mode is getting a face lift, there are some weird inputs here and there, for a future update, but have fun

V19.1: Animation updates

V19: Broadcast HUD, Defense Scanner, and Input Reliability

July 13, 2026

V19.0

The live HUD has been rebuilt into a more broadcast-style presentation with animation and clearer information.

There is also a badge that shows whether you were hit high, low, mid, or by an unblockable attack.

Mission Mode has received additional route and input-handling adjustments.

V19 ^

V18.7: Dolphin Black Screen Fix and Read-Only Input Monitoring

July 13, 2026

A major production bug was found while testing the new input systems.

During input experiments, some debugging and Gecko-related code was accidentally left enabled. That experimental path could reach into Dolphin's folders, modify Dolphin.ini, alter game configuration files, enable debugging, and leave Dolphin launching games into a black screen until the affected configuration was reset.

This behavior has been removed.

I will now keep a stable build from this point forward.

V18.6.2: Mission Mode Input and Combo Fixes

Mission Mode now uses raw inputs for move checks and the Down, Down, Taunt mission menu.

Trials now confirm hits faster, allow extra moves between required steps while hitstun remains active, reset faster when hitstun ends, and require fresh inputs for repeated loop steps.

Mission Mode no longer activates Megacrash Trainer, which was a bug I was unaware was happening until recently. Regression testing will continue to be updated.

V18.6.1: Enhanced Input Display and Charge Tracking

The input display has received another upgrade.

Directional inputs now use images, alongside dedicated icons for neutral and button inputs, making everything much easier to read at a glance.

A frame counter has also been added, so you can see exactly how early or late each input was.

On top of that, holding a chargeable button, such as Zero or Condor, now displays exactly how long you have been charging it.

V18.5.1: Live Input Display

After dragging my feet, I found the raw inputs. I should have done that first, but now you can see exactly what your inputs look like at all times, so now you truly know if you teched that.

V18.5: Advantage Matrix and Punish Finder

And with that being said, I now have the Advantage Matrix.

Click a move and see how you could have punished that. Chun keeps poking with 2A, who can punish that?

Oh, all these people? And here is their startup? Excellent.

V18.4: Observed Frame Advantage and Regression Testing

To keep the story short, the frame data derived from the source takes some assumptions, and there are some windows that were not found, so some frame data came out a little weird. Not all of it, but about 70% could be trusted.

I have now personally calculated frame advantage. In the frame data window there is now derived block advantage, which is what the program calculates from the details found so far, and observed block advantage, which is personally tested and much more accurate. This has also been ported to the Normals Preview window.

Also, I do not think I mentioned there is regression testing in here. Because there is.

V18.3: Yami Arcade Fixes and Live CSV Exports

Yami has been fixed. You can now play Arcade Mode. There may be one more error message in Training Mode, but it is inconsistent.

Also, for the nerds, as you play there will be an output CSV in data/exports.

V18.2.3: Clearer Win Count Display

Win count was also a little confusing. It should now make a little more sense.

V18.2.2: Megacrash Trainer Flow and Stability Fixes

Megacrash Trainer was a little confusing and did not work entirely as intended. It is now flowing much better.

Minor bug fixes.

Bug found: Yami crashes when Win Score is on. I never accounted for Final Stage. Not fixing it yet, just a heads up.

V18.2.1: UI Cleanup and Extra Character Clarity

Some cleanup on my side. This should not affect anything user side.

Extra characters now show as a Ryu icon for clarity. The solo slot shows as Zero.

V18.2: Post-KO Wins and Frame Data Fixes

Post-KO wins are now fully functional, with one exception. Zero and Frank have special KO screens, so at the moment they do not work.

The Frame Data GUI had a few bugs. These have been resolved.

V18.1: Vertical Range Ruler

Vertical Ruler added to Range.

V18: Major HUD Overhaul, Move Ruler, and Ghost Hitboxes

Open V18 release details

And unfortunately this change was so severe I had to move to V18.

The onscreen HUD got a massive overhaul. I am hoping this is cleaner, easier to see, and does not take up so much real estate like it did before.

Frame advantage is still on the HUD, but it also has its own card at the top. This can be toggled off.

A new combo card is added, so you can see exact damage and meter gain. I need to add Baroque, but that is not today. This can be toggled off.

Tag-ins also get their own card. This can be toggled off.

There is now a move ruler.

When it is blue, you are out of range. But when it is green?

The move is ready to hit. This is still a beta. Some rulers are off. The game will attempt to adjust, but some are still broken. For the most part they should be accurate.

Ghost hitboxes are also in. Hitboxes were difficult to see, and still are, but trailing hitboxes give you a better way to visualize their range.

V17 and earlier: Legacy Features, Fixes, and Release History

v0.17.6.1Ref Spec was not updated, so the blockstun and hitstun values did not work on EXE export. They are working now.
