I am trying to run Any% All Glitches and wanna try and do MMS. Even though I can get the glitch by spamming, i just can't find a good, practical way to do it. Any help is appreciated.

MMS is kinda complicated to explain, you have a single graphics frame to get the input on 1.3+ so playing at something like 400fps isn't adventageous

If possible join the speedrun discord and ask there, there's newer "routes" for any% AG currently being developed and people will be willing to help there
