Hammer Brothers' Behavior (I'm including all commented information on this first post with credit given)

All information (so far) assumes -3.27 as starting timer, and a "perfect" run up to 8-3 ~~~ 370 1-1, 346 1-2, 340 4-1, 354 4-2, 200 + good judges in 8-1, 342 + extra framerule

NOTE: there is currently an inaccuracy - as the reports are discrepant, either an error on my part or on one of the contributor's parts. If you know what is incorrect, please comment. I'll try to work out what's wrong, but this is what I have so far. I'll try to run it myself to check, but I won't have time to play with it for a few days. Once the reports are reconciled, I'll merge them into a more coherent single report.

XxXxXxXxXxX +0 Framerules ~~ -0.00 with -3.27 as starting timer (~337.9) XxXxXxXxXxX

Lul_ee_ducks ~~~ First set of Bros are out of your way, one on top bricks, one on middle. Second set will have both bros on bottom. 1st Bro on ground, Jump over, Second Bro, Jump over, Third Bro, Jump Over, Fourth Bro, Go under. Make sure you kill no Bros.

XxXxXxXxXxX +1 Framerule ~~ -0.35 with -3.27 as starting timer (~338.3) XxXxXxXxXxX

Lul_ecks_dee ~~~ First set of Bros are in your way, one on middle bricks, one in your way. If you hit both of them, this is your pattern. Second set of Bros, one on top bricks, one on ground, go in the middle. Do not kill the Bro on top. 1st Bro on ground, Jump Over. 2nd Bro, Jump Over, 3rd Bro, Jump Over, 4th Bro, Jump Over. I do not know what happens if you kill only one of the bros.

eddiecatgaming ~~~ The first set of bros. are nice. The first is at the very top and the second is in the middle. The second set of bros. are nice. The first is at the very top and the second is on the bottom. The gauntlet is very nice. If you smash the top bro in the second row it will go down like this: The first two bros. will not jump. The fourth will try to jump when you do, so go under.

Darpey ~~~ link = The first set of bros is nice, killed the middle one (top/middle), second set is bottom top, so run through middle, killed the top one - the last bro of the gauntlet jumps, so run underneath. (in retrospect, I shouldn't have made these kills, but if you do kill both of those bros, the last one will jump)

XxXxXxXxXxX +2 Framerules ~~ -0.7 with -3.27 as starting timer (~338.6) XxXxXxXxXxX

Lul_ecks_dee ~~~ link = First set of Bros are out of your way, just like in -0.00. Second set of Bros are just like in +0.35. All the Bros do the same thing you would in +0.35. Make sure that you kill no Bros.

eddiecatgaming ~~~ The first set of bros. are exactly how they are before (one in middle one in bottom, kill them both) The second set of bros. is nice. Both of the bros. here are guarding the bottom. The gauntlet is, once again, very nice. The first two bros. will not jump. The fourth will try to jump when you do, so go under.

I just got a 5:00.5 (unverified) last night, and am now working on a relatively small amount of rules for bros in 8-3. Does anyone have information on bro behaviors in the 5:00 to sub-5 range? I was going to spend a few hours finding out what exactly they do in each rule, but I figured it's likely someone has information on that that they would be willing to share. Also it seems like it would be a very useful public resource to have available.

I know that it's dependent of course on what you set your timer on, and what bros you kill along the way, but most people that aren't doing bbg probably set their timer on the typical 3.27 - so all runs from low 5 to high 4:58 are (probably) starting on the same frame.

Anyone have that information and is willing to share?

I don't know, but I am intrigued.

You said the same message 3 times... Anyway, I know that if you start the game as soon as possible (-3.27), and play "perfectly" (no BBG, FPG, 1-2G, 4-2G, 4:58 pace when entering 8-4)

-0.00: First set of Bros are out of your way, one on top bricks, one on middle. Second set will have both bros on bottom. 1st Bro on ground, Jump over, Second Bro, Jump over, Third Bro, Jump Over, Fourth Bro, Go under. Make sure you kill no Bros.

+0.35: First set of Bros are in your way, one on middle bricks, one in your way. If you hit both of them, this is your pattern. Second set of Bros, one on top bricks, one on ground, go in the middle. Do not kill the Bro on top. 1st Bro on ground, Jump Over. 2nd Bro, Jump Over, 3rd Bro, Jump Over, 4th Bro, Jump Over. I do not know what happens if you kill only one of the bros.

+0.7: First set of Bros are out of your way, just like in -0.00. Second set of Bros are just like in +0.35. All the Bros do the same thing you would in +0.35. Make sure that you kill no Bros.

What +0.7(?) looks like That's all I got

@Lul_ecks_dee pocket types it, on my phone at school.

if you did -3.62 as your start time, and did everything perfect (370 1-1, 346 1-2, 340 4-1, 354 4-2, 200 + good judges in 8-1, 342 + extra framerule) up to here, and you wanna know what the bros. do, read below.

The first set of bros. are nice. The first is at the very top and the second is in the middle. The second set of bros. are nice. The first is at the very top and the second is on the bottom.

The gauntlet is very nice. If you smash the top bro in the second row it will go down like this:

The first two bros. will not jump. The fourth will try to jump when you do, so go under.

If you did NOT get fast 8-2 and good judges, or bad judges and fast 8-2, and you're doing -3.62, it will go like this:

The first set of bros. are exactly how they are before. The second set of bros. is nice. Both of the bros. here are guarding the bottom.

The gauntlet is, once again, very nice.

The first two bros. will not jump. The fourth will try to jump when you do, so go under.

The very top pattern I posted is for ~4:58.7 runs. The bottom patern I posted is for ~4:59.1 / 4:59.4 (depending on if you do walljump in 8-4) runs.

If you would like to see proof for the 4:58.7 pace bros., please watch my 4:58.741 SMB1 any% PB, and you can see exactly what to do for the bros. that are here.

If you would like to see proof for the 4:59.1 / 4:59.4 pace runs, please watch my obsolete 4:59.490 any% run, and you can see exactly what to do for the bros. that are here.

Hope this helps!

edditcat - curious - what's the reason for doing 3.62 instead of 3.27? for better framerule behaviors? excuse my ignorance.

Also there appears to be a discrepancy between your (eddiecatgaming) and Lul_ecks_dee's accounts - your 0.0 ought to be the same as his +0.35, right? based on your starting timer.

I'm working on merging the two into the original post.

I always thought that people start with -3.62 because your less likely to have a title screen fail. But that's just my guess.

I only did -3.62 because most runners around the sub 5 range (including me) use this start time.
