Mega Man 3 ImprovementDescription

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

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.

** The included MegaFLE.dat file is needed for MegaFLE 0.701
** The included 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.
** The included text table.tbl file is to help with editing story text

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

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

** Stupid item flash again... This time megaman would not flash anymore during the "get hit by enemy" animation. Fixed that.
Thanks diablo666

I'm really starting to regret ever adding this item flash addition, I didn't realize it would cause so much trouble in many ways.


November 29, 2019 - Attempt to fix item flash

** Fixed energy flash bug hopefully. Very shameful mistake I did not notice, ugh.

** Fixed Weapon Icons from being glitched if you swap by jumping at the top of screen + Start of levels, and breakman battle.


November 12, 2019 - Updated again with some more fixes, etc.

** IMPORTANT!! - Multi path and CHR animation editors added to Misc Editor screen for MegaFLE, both function exactly like megaman 5.

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 in Doc Gemini, so you don't need Rush Coil or Softlock the game.

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

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

** Preload Palette animation for Boss refight room before scrolling into it. Originally showed grey's until screen fully scrolled in.

** 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 if there 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.
