Hey man, been playing your Xpos rom for the past few hours, really appreciate the work put into it! I can get a similar graphical glitch in 4-1 sometimes, but that doesn't seem to lead anywhere. Merry Christmas!

The freeze has been TASed and explained on Tasvideos: http://tasvideos.org/forum/viewtopic.php?p=430654&highlight=#430654 There's also a comment there that says lag is different on FDS, so that may be something to look into.

There is an overflow glitch with lag sometimes. Sockfolder looked into it and said there is no potential for memory manipulation with it, but it could probably take a second look by another expert just to be sure.

The 8-2 despawn probably meant the flag. In A-3 of Lost Levels you can despawn the flag with enough fishes and get an automatic fpg saving a framerule. 8-2 seems like the only any% level where there could be enough enemies.

I also had the idea for 8-2 to use the last Koopa in the level to clip into the ground like the warpless TAS does in many levels. But I think I tested every possible spawning pattern of the last Koopa and it never fell into the right hole.

By 8-2 despawn he meant despawning the plant that is in the pipe so you don't have to slow down as much. If this despawn was possible then saving another framerule would be easier. Also for the thing about getting the koopa into the right hole. If you scroll mario to the left side of the screen than you can hit him earlier than you would usually be able too and make him fall in to the right hole.

For the 8-2 plant despawn: https://pastebin.com/HdRmpA8i Also, this will require 6 bullets on the screen at one time. I'm not sure if this is possible, but hopefully it is.

Bullets only spawn in enemy slots 1-3.

crap

I believe that not slowing down as much in 8-2 results in fireworks. I am not too sure, but when doing AISSON I got 6 fireworks on 8-2.

You won't get fireworks if you do bbg.

Ive gotten fireworks with bbg, tbh it took a couple tries to get the right shot. I dont know when you would arrive the flag without slowing down as much, but you can still get fireworks.

The any% tas uses the same mathod to clip in 4-2. But it still saves the FR. How does the tas do it differently that is much faster?

Refrase: How many frames do you have to save in 4-2? Is the fast-accel the reason the tas saves the FR?

I'm saying that if you get to bullet that fast and you get optimal shot you will not get fireworks and you will save one framerule over the current any% record
