While Baxter is climbing on some mountain in Germany or in Switzerland, I'll try to figure out the route. So the issue was to try find a perfect route for the purpose of ending all games simultaneously. Below are the routes for Mega Man 3,4,5 and 6 and how long it took to complete each stage (approximately, I used the .avis as reference):
Mega Man 3: Mega Man 4: Mega Man 5: Mega Man 6:
1. Gemini Man 1. Pharaoh Man 1. Star Man 1. Flame Man
(2:20) (2:25) (2:05) (2:14)
2. Needle Man 2. Bright Man 2. Gravity Man 2. Blizzard Man
(1:46) (2:36) (1:51) (2:01)
3. Snake Man 3. Ring Man 3. Gyro Man 3. Plant Man
(2:11) (2:52) (2:12) (2:17)
4. Magnet Man 4. Dust Man 4. Charge Man 4. Tomahawk Man
(1:45) (2:01) (2:00) (2:19)
5. Hard Man 5. Skull Man 5. Wave Man 5. Yamato Man
(1:53) (2:04) (2:03) (2:01)
6. Top Man 6. Dive Man 6. Crystal Man 6. Knight Man
(1:51) (2:05) (2:02) (2:15)
7. Shadow Man 7. Drill Man 7. Napalm Man 7. Centaur Man
(1:42) (2:13) (2:03) (2:17)
8. Spark Man 8. Toad Man 8. Stone Man 8. Wind Man
(1:50) (2:04) (2:15) (2:10)
Note: There is 1-2 second margin of error. Measurement: Besides stages 1 and 8, once the menu screen appeared until the next one was how I measured each stage. On another note, everytime Mega Man must go through a
left-zone will most probably cause difficulties for us knowing that about 90% of all the zones requires you to move to the right.
