Mega Man 3: Mega Man 3 Improvement

This is an improvement patch for Mega Man III/Rockman 3. It has many improvements to the game + MANY bugfixes that existed originally in MM3.

Anyone is free to use this for their own Mega/Rock 3 hacks, and any new ones in the future.

Please only use the appropriate patch depending on what ROM your using. The megaman3 patch is only for the English version and the rockman3 is only for the Japanese ROM.

The author will not list all the changes here, they are already listed in the readme. A YouTube video was uploaded also to demonstrate many of the changes. Please see the “Video Comments.txt” for the link to the YouTube video and to use as a guide to note the changes you’ll see demonstrated.

An ASM file was used from the Japanese ROM hacker named Puresabe, known best for Rockman 4 MI (Minus Infinity). It implements some gameplay physics mods that he presented to me. NOTE: It already has been applied to both English and Japanese versions of the patch.

A few things added from this post + bug report from #rom-hacking IRC

October 10, 2012 - Version 1.0 - First beta release at 2ch.

----------------------------------
Please apply to a clean megaman, or rockman 3 ROM.
This is free for public use, and any future mega 3/rock 3 romhacks.
ONLY use the appropriate patch. The rockman 3 patch is ONLY for a rockman 3 rom, and megaman 3 ONLY for megaman 3 rom.

I recommend having a backup of your ROM before applying the patch if your using it for a romhack.

** MegaFLE.dat file is needed for MegaFLE 0.701
** MegaFLE X.exe is a slightly edited copy with CHR and Multi Path edtiors now included for Megaman 3. These function exactly like megaman 5. Replace with the original MegaFLE 0.701 in it's folder. Backup first!
** text table.tbl file is to help with editing story text
** Manual fixes.txt is for people who want to revert the most commonly complained edits, and/or Rush Jet energy drain.

** Please see this thread for adding Famitracker songs, or asking for help/etc:
https://www.romhacking.net/forum/index.php?topic=36763

Anything marked "IMPORTANT" are major fixes, or improvements to the game. So please take note of those.

https://www.romhacking.net/forum/index.php?topic=36763

** IMPORTANT!! For authors, Energy Balancer and Weapon Tanks can be added to hacks if desired. They are on 2nd page of Weapon Menu. Use Sprite ID 4F (W.Tank) and ID 5B (E.Balancer, GFX Set 5) in MegaFLE.

** un-used Wily Machine debris object, and un-used 3rd frame for energy balls, added to battle.

https://www.sprites-inc.co.uk/sprite.php?local=Classic/WilyWars/Enemy/

** Fixed Hardman "double hit" glitch, so you dont take 10+ damage.

** Fixed moving platforms in Wily 3. If you were at bottom of a ladder, megaman got pushed across screen in Ladder Climb state.

** Small graphic edits: Protoman and Sparkman have proper faces. Credit to romhacks "Megaman 3 Revamped", "Roll-chan 3 Improvement"

** NEW - Sound ID #49 - Bounce sound for trampoline guy's jump. (Snakeman/etc)

----------------------------------
Feburary 14, 2022 - Just addressing remaining known softlocks, if you have no rush coil/jet ammo.

** Address softlock potentials on 1st screens of Doc Spark, Wily 1 (still require rush coil, no softlock), and Wily 3.

----------------------------------
July 26, 2021 - Extra fixes and edits I intended to do in the past, and did for the romhack Megaman 3 Revamped after Ver 2.22 + Few more un-used graphics found and restored.

** Some more lag reduction

** Weapon swapping with select button now has Select + Up/Down - to cycle weapons left or right, instead of only right previously.

https://tcrf.net/File:MegaMan3_UnusedBreakManMugshotAnimation.png

https://themechanicalmaniacs.com/articles/mm3mysteries.php#Graphics

** un-used spark shock for sparkman battle - applied to mm when hit.
https://themechanicalmaniacs.com/articles/mm3mysteries.php#Graphics

** A 2nd softlock addressed, before Flash Man boss room.

** Disabled hitbox of hard knuckle walls, when explode animation is active. This was found from romhack "Megaman at the Tokyo Olympics"

** Fixed top of giant snake midboss so you can't pass with Rush Jet.

** Fixed penguin egg's explosion repelling shots.

** Fixed 1-frame tile glitch on all boss fights when they spawn. This was most noticeable on Wily 1, and Gamma's head.

** Fixed lifebar display glitch on 1st form of wily machine where it shows full HP for 1 frame, then normal. When shooting the cannon.

** Fixed megaman glitched when entering boss rooms with Rush Marine.

** Fixed dieing on same frame you start a down-scroll, where music stops playing, and you don't actually die. Doc Shadow for example.

** Added breathing bubble for Rush Marine, shared with base water. Marine has his own un-used type, but animation data was in-complete.

** Face megaman to the right after gamma battle. This can not be done for the laying on ground frame as it does not have "right" data

** Trash blocks (Sparkman/Doc) easier to pass by, after destroyed.

** Proper jump animation for Woodman/Quickman at start of battle.

** Music will fade out when exiting completed levels, and after defeating any of the game's boss fights.

** Adjusted hitboxes of some things to more accurate sizes. They are usually slightly larger than the sprites themselves.
** geminiman, snakeman, leaf sheild (woodman), large spark shock (sparkman), seperated turtle shells (wily 1), hedgehog rolling ball

** Water splash Sound ID #2F for Wily 1 turtles, and submarine's missles moving outside water

** NEW - Sound ID #3F - Needle sound for Hedgehog and Needleman's needles
** NEW - Sound ID #40 - Missle sound for Missle Launcher, and bullet cloud, Hammer Joe enemies
--------------------
For romhack author's making new Megaman 3 hacks in the future

** IMPORTANT!! Slippery Ice/Floors TSA Block property can be added to levels. This is Type B on the TSA Table editor screen. Imported coding from my un-finished Megaman Odyssey.

** 8 Multi paths settings supported now instead of 4.

** All level's screen data edited in MegaFLE. To make it safer for authors to edit extra screens. Previously, unused "screen preset" and scroll maps were harmful corrupt data in un-modified megaman 3.

** Auto detect enemy position # when spawning at checkpoints instead of reading from level data. Many megaman 3 hacks had softlocks at boss rooms, from not updating checkpoints after add/remove enemies.

** All existing enemy types now have their own base horizontal X speed, instead of being shared by multiple enemies.
Tables at $610-$69F (low byte) and $710-$79F (high byte)

----------------------------------

December 1, 2019 - Attempt to fix item flash.. take 2

----------------------------------

Please place sprite type 28 with Y position as the ID number (80, 81, 82, etc) to start animations, and type 29 with Y position 0 to disable animations. See gemini man for example. (bubble fish from gameboy megaman 3)

** IMPORTANT!! - Wily 3 and 5 no longer shared level data. Both are seperate levels now, and can be designed with a full 32 screens if desired.

** Removed a block after Flashman battle to prevent softlock.

** MM Clone Boss edited to make the very 1st clone set random, "not" start with only top.

** Item drops will blink for 1 second when close to disappearing, instead of instant.

** Fixed Hard Knuckle from freezing megaman for a long time in the Boss refights when you defeat a boss on final hit.

** Fixed Screen wrapping with top of screen. example: Cant grab weapon refills in Doc Needle from the top of screen when there at the bottom. Megaman will not be damaged by enemies either at the bottom.

** Fixed Gemini Laser "off-screen". Now despawns properly the instant it goes off screen at the top so you may shoot again, and not wait.

----------------------------------
