The time has come when I'm going to review between 2 of Chiko's Rockman 5 hacks when they are currently in use. One being removed and one being hosted in public.
First off, Chiko's 2nd Rockman 5 hack is the VERY first release of Rockman 5 Dood in Gate which is August 23rd 2009. I have played every single aspect of the game and I didn't find it interesting but it beacame too easy for me. Until the significant changes came along for each release.

November 21, 2009 (Present)
Star Man stage fixed at the "GO DOWN" scene.
These are the differences of 2 two games.
Title Screen
Rockman 5 Dood in Gate design and palettes are really AWFUL. But I don't know exactly what it means. I know for a fact that it looks sort like a map of Japan. I am not much of a Japanese reader, but it says "Yatsunu" when they found who is the main culprit of the game. In Dood in Wily's Last, it says "Wairi" meaning Wiley or Wily and words are colored like Rockman 5 Wily's Dream Space. It's palette swap are almost similar to it. They even have the Wily coil like on Rockman 3. But in Chiko's 2nd Rockman 5 hack called Rockman 5 Dark Return, It reads
"Yamika" meaning shrouded in enternal darkness. They even have 3 dark enemies in the title screen.
Stage Select
The original version have some bricks in the background while Dood in Wily's Last just have a black background with other polished decorations. Even the bolded text. Chiko didn't actually palette quad the potraits which is why Wave Man and Napalm Man have the same palettes when I patched Roll Chan 5 into these hacks. However, it's shiny parts palettes are also changed. I don't think the stage select screen isn't that important.
Wave Man's palette seems like Zap Kraken from the first release of Dood in Gate in Megalion 2 created by Kelvin the Lion until Chiko recolored it in the later versions of the game. The same goes for Crystal Man between the 2 palette changes.
Gyro Man's Level
It is one of my favorite stages in the game and it's a bit easier than I expected. But the boss is still too hard. Unlike Dark Return which is really unfair after too many retries trying to beat him, Gyro Man is now one of the medium difficulty boss is even known.
What's even more great about Gyro Man's stage is the music. Played from the game RosenkreuzStilette stage 1 of Iris Sepperin. The graphics are almost original.
Crystal Man's Level
The original version of Dood in Gate just have the back and foregrounds of Flashman with the flashing spikes. Don't know why is not the opposite. On the screenshot when Roll Chan is riding on the infinite Super Arrow which is no longer used in later versions. There is an error on the map editing in the first release. However, the 2nd version of Rockman 5 Dood in Gate have upside down metools. Why this version have them now. It still makes them hard.
When Dood in Wily's Last arrived, it has changed into more crystal cleared stage but way too hard to beat. You have to be a master to reach Crystal Man but his AI is way too worse than Dark Return. The graphics are used with SMB2 Vines, Brambles from Donkey Kong Country 2, Rockman 2 Grayzone (Possibly Rockman 6 orginally), and Ice from Kirbys.

What really bothers me is the Gordo Spikes are now used that Tar originally planned. Of course, they are ripped from the Kirby game.
Star Man's Level
November 20th, version.
The original Star Man's Level is quite original. However, most of the ripped graphics are also used. Especially the unused tiles from Crash Man in Rockman 2. Difficulty is Medium. The Dood in Wily's last version seems a bit hard but also contains some ripped graphics from Sparking to Hero and various others. Also note that the foregrounds are nearly the same as Wily 2.
Dood in Wily's last is difficult to obtain one of the Beat parts and there are soild bricks in the way. While Dood in Gate, you can choose which path to go to get them back in the October 19th version. The November 20th version of Dood in Wily's Last made it unfair in the hidden ladder scene which I don't know where it is.
Gravity Man's Level
November 20th, version
Gravity Man is one of the hardest stages in both versions. First off is that Dood in Wily's Last uses a similar variant as Wily's Dream Space when you reach the checkpoint. And the graphics themselves also similar to Wily's Dream Space especially Super Mario World 2 Yoshi's Island.
While Dood in Gate uses Magnet Man and part Kirby graphics and is not well designed. Thank Goodness. And is far too worse to complete.
Napalm Man's Level
Stages like those shoudn't belong in neither game. First that the original Napalm Man stage have part Needle Man graphics and others and is not properly designed. Napalm Man became clear until Chiko added new enemies in the 2nd version of Dood in Gate. And there are also some Boss room changes also.
While Rockman 5 Dood in Wily's Last, Chiko completely changed the stage layout to Quickman's stage from Rockman 2 Grayzone.

]
The stage acts exactly as if were used in Rockman 2 Grayzone but with Rockman 5 WDS conveyor belts. Most importantly, some of Crash Man tiles are used and some others too I don't even know.
The November 20th version of Dood in Wily's Last has built something more original. Almost but graphics are continously taken from Rockman 5 Wily's Dream Space. These graphics are originally taken from Rockman 3, Rockman 6, and Super Mario Brothers. The level themselves isn't very pretty either. Don't you think that the new Napalm stage seems similar to Flash Man from DHI's Rockman Exhaust hack?
Wave Man's Level
Wave Man's stage has been changed for a little bit from either versions especially the undesigned part in this screenshot which is used for riding the jetski. Whatever happened to the sun from Rockman 6. Wouldn't make it a better background than pieces of squares.
The November 20th version has been corrected. As well as the smiley face at Wave Man's room has been remodified.
Charge Man's Level
The boss rooms changed in the 2nd version of Rockman 5 Dood in Gate written "HEAT UP". Graphic uses are Super Mario World 2 Yoshi's Island, flames and other scenes are from Rockman 2 Grayzone. Chains are from Super Mario Brothers 2 which come from Napalm Man of Rockman 5 WDS. The November 20th version ripped graphics directly from Rockman Sparking to Hero, Maverick Revenge/Grayzone Wily 3 which came from Wily 2 in Rockman 4, Rockman 6 and from the last previous versions. Both stages difficulty is medium.
Stone Man's Level
Unchanged from the original version. Uses Ice graphics from Mario, Rockman 4, stolen from Rockman Sparking to Hero, and Wily's Dream Space.
Blues StagesBlues 1
Redesigned levels and few enemies Added.
Blues 2
Enemies Added
Blues 3
Redesigned levels and few enemies Added. Graphics stolen from Sparking to Hero's Dustman.
Blues 4
Darkman AI?
Wily's StagesWily 1

Wily 1 from the original version uses Rockman 3 and part Kirby graphics and Dood in Wily's last stole it entirely from Gravity Man's Wily Dream Space. I wonder why? Both stages uses flashing foregrounds which they kinda annoying.
Wily 2

Only the ladder scene changed. The Rockman 2 Grayzone parts remain unchanged.
Wily 3
Capsule room changed.
Wily 4
Redesigned level.

Chiko have completely changed Wily as the final match in Dood in Wily's Last instead of the weird looking Yatsunu. At least the weak point remain unchanged. Well not really, it just makes it more harder to reach.
And there you have it, these are the major differences between the two. Don't know why it should have been the first release but Chiko must've changed the ideas completely and could have created another one like it. And finally, I have the attachment file of the original Dood in Gate from August 23rd 2009 version that Chiko deleted it off his website (Or Webfile as the uploader) for newer versions.
Currently, I think Dood in Wily's Last is really awful and I give an overall rating of three. Seriously.
Future plans for ChikoI predict that Chiko may rip off Ririka, kuja killer, Insectduel, and infidelity's work sometime but clearly I hope not. Esepcially if I have my own Mega Man IV project in progress. My Mega Man 1 project may be on Ice but dosen't mean that Chiko can use my ASM work but he is welcome to take my crappy ladies and 1 thrown stage.
