=== Emulator Training Tools ===
I have created a set of scroll glitch training tools (along with other cv1 helper tools). These currently require using bizhawk, although I will likely port to other emulators in the future.
https://www.speedrun.com/cv1/resources
Helpful tools included are:
1. Create lines onscreen to show turnback locations
2. Auto-death tool - kills you if you miss a scroll glitch
3. Turnback-Turnforward diagnostic printout (to highlight if you really are hitting 2-14 or 4-12)
Note, if you are using original hardware, the above tools may be a little annoying as the input latency is different. I would still recommend trying them though as many scroll glitch execution strategies are not latency sensitive.
=== Rhythm Sounds ===
If you are trying to learn a whipless rhythm approach, sounds can also be a helpful aid. You hit the buttons on the appropriate beat. Every frame is 1/60th of a second (technically 1/60.09), so you can use that to create a beat. One style is to do 4/60th of a second followed by 12/60th of a second. Another is to just have a metronome set to 16/60th of a second and time either your forward or backward presses to that beat.
Attached is an MP3 created for the 4-12 pattern: TO FILL IN

InfoManiac
Originally discovered the scroll glitch. The initial method only worked on TAS
Challenger
Implemented almost all the current scroll glitches in TAS that have since been ported to RTA by others.
NatGoesFast
Accidently did a scroll glitch on stream. An investigation of this led to the whip based RTA strategy discussed above.
SBDWolf
Found the whip based RTA viable approach for stage 13 and stage 14. Also figured out probably 75% of the basic block updating algorithm and RTA strategies such as odd/even frames approach. Also was the first person to use these scroll glitches to get WR. (May have also found the crusher room scrollglitch).
Shockratease
Along with SBDWolf, did extensive investigation and teaching on the scroll glitch. Suggested using 16/60th beats instead of two-part beats.
Kajong0007
Created the Romhack mentioned above, which has been used extensively by runners to better learn the trick.
JayCee
First person to remove whips for turnbacks and use it in runs. The removal of whips also enabled a lot of additional scroll glitch areas (crusher, clocktower) which did not seem viable otherwise. This inspired additional scrollglitch innovations.
Trisk (tr1sklion)
Wrote this document. Found the Block Counter and Column Update Window in the game bytecode. Validated and enhanced the earlier algorithm approximation SBDWolf modeled. Wrote the Bizhawk training tools. Pioneered the 4-frame turnbacks strategy and most correction strategies.
