After a discussion in the discord, we have concluded that the only real benefit to being able to watch the RNG ram values in real time (0x030007FC xxxx and 0x030007FE xxxx) is retroactive viewing for research purposes.
Therefore, until a way is discovered to take advantage of seeing the RNG advance in real time during runs (in a way that would alter the runner's decision making), having the values on screen is totally encouraged for emulated GBA runs in the name of figuring some more stuff out about how this version of the game operates under the hood.
Nobody wants to dedicate entire runthrough attempts to capturing the ram values if they're just gonna wind up being invalid for the leaderboard, and loading from savestates will often lead to inaccuracies, so for the time being this seems like the best course of action. We will be sure to update everyone as soon as we find something out and/or decide to reverse this decision.
Just to show what the inclusion of the RNG values looks like on my stream, here's a short clip:
I open the ram watch window in mGBA, input the first RNG value, window capture the ram watch window, and crop so that only values C through F are shown. This is all that needs to be done to show the stream what you're seeing as you play.
