Is a sub 6 minute run possible? I'm gonna go out on a limb here and say no. It's impossible unless someone finds a way to realize the savings I think are blocked by some built-in game mechanics That being said - here are some theoretical areas where time could be saved Stage 3 Bridge area - throwing mobs into pit with elbow if someone figures out how to get all enemies to fall immediately into pit with single elbow in both fights, 7 seconds of time could be saved Stage 3 - Double Bolo fight If the glitch I discovered in 6:17 run can be used on both Bolos at same time, 8 seconds could be saved. Again - not sure if possible. The game would have to allow both Bolo's to try and throw Player at exact time time, AND prevent that second Bolo from trying to pick up a boulder. Stage 3 - Green Bolo fight If someone figures out how to guide him off cliff immediately - 4 seconds of savings could be possible Stage 4 - Double Bolo fight If someone figures how to immediately knock Bolos off bottom edge with elbow - 16 seconds of savings could be realized. This alone would make a sub 6 minute run possible. This would require someone to work-around the game's built in edge detection. These two mobs have a built in protection to not hit the Y-coordinate necessary to knock them into the pit with an elbow. This video from demonstrates the built-in protection https://www.youtube.com/watch?v=LQu8zlqi0SY The other way to make this happen would be to trigger the Double Bolo fight while still leaving room to fight in bottom left chunk of walkway. This is also impossible (even if you use 2P as well). The X-width of screen prevents you from hitting battle activation point - even when 1p sits back and 2p attempts to reach battle activation point That's discouraging! Do you really want someone else to hit sub 6 run? Hells Ya! I would love to see someone hit sub 6 - hence the notes I captured above. I don't think it's possible, but I would love to see it done (I'm still trying myself), and those are the areas that could make a sub-6 a reality

Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

No dice. I tried the build you linked me to, this one also goes out of sync even faster than FBA-RR I've been testing with ddragonb2: Double Dragon Bootleg ddrabonb: Double Dragon Bootleg with HD6309 I'll tinker with US, World and Japan sets to see if I get different results.

Sugarfoot, I'm curious why you're using a bootleg Double Dragon set to TAS with in the first place, when bootlegs are more likely to cause problems than "official" releases. The parent ROM in MAME is the Japan version, why not just use that?

Yes, standard runs are needed and very appreciated here too

No technical reason - A) I'm brand new to TAS'ing, and B) it just so happens to be the ROM I've been using since 2005. I wasn't aware the bootleg ROMs would cause emulation problems. I'll switch over to the parent ROMs from now on. Thanks!

Now that I've finished a 6:17 run of this game, I don't know if a sub 6 minute run is possible (outside of using some game ending glitch) :( There's not a lot of places left in the game where timing can be saved - unless someone finds a way to get the throw all the bolos off the cliffs immediately - throughout the entire game.
