I have found a strange but funny trick at the End of Time, which turns the boring chat into an entertainment show and also saves a few seconds. Here it is.

As for the progress of my testrun, here is the current status.

As usual, I left out a part of being unrelated to my strategy from the movie. If someone likes to see other parts such as the rat chase or the bike race with Johnny, please let me know. I'm willing to post the movie which includes those parts.
Actually, this movie is almost the same with my run on SDA except for the better luck manuplation at the fight with 5 Alkalines. The more important thing is that I found addresses which decides the combination of Acids and Alkalines.
Here are those addresses.
7E1425,7E1427,7E1429,7E142B,7E142D
They take a value of 6 or 7 when you enter the room to fight them, and if the value is 6, an Acid appears, and if the value is 7, an Alkaline appears. That is, you have to manuplate the luck so that all addresses take the value of 7 in order to see 5 Alkaline appears. And fortunately, it's quite easy to do that luck manuplation, since they have the same value every one minute.
Here is the list of all combinations of the values in one minute.
66666,66666,66666,66667,66677,66776,67767,77676,76766,67667
76676,66766,67667,76677,66777,67777,77776,77767,77676,76766
67667,76677,66777,67777,77777,77776,77767,77676,76766,67666
76667,66677,66776,67767,77676,76767,67676,76766,67666,76667
66676,66766,67666,76667,66677,66777,67776,77766,77666,76666
66667,66676,66767,67676,76767,67677,76776,67766,77666,76666
As you can see, it is only once a minute that they all take the value of 7. Perhaps, there are several errors in the above list, but that won't be much problem, I think.
Also, as for the later three boss battles, Heckran, Zombor and Masa&Mune, I am planning to use somewhat different strategies from the one hero and I used. I guess the new strategies could save 10 seconds in total at least. Anyway, some test will be needed to find it out.
