Description: We all know (and have a love/hate relationship with, at least for the most part) Golden Sun's broken and/or easily manipulatable random number generator. This IPS file aims to patch that so the prng is both essentially unmanipulatable (at least without codes/forcing it to certain values via ramhacking...), AND is more uniformly random (meaning better AI capabilities for enemies!).

As of this version, both of those features are already in, but it still needs testing done on it to determine how much more random it actually is compare to vanilla --- and whether any further adjustments are necessary. Hence me posting it here for more viewers / users than just on the discord.

edit: Just for transparency's sake, this code adds an additional prng formula setup (based off the one at 08014878 in ROM, with the additional code tagged on at the start) in a minor amount of free space at 080C9620. This is pointed to by an adjusted pointer at 080CA09C that will call it instead of 08014878.

Note that this ties the reseeding to the first directional movement input made after every new room load / battle won; while this much is functional + does not break the game, I cannot stress enough that this IPS still needs testing done on it to confirm the changed randomness works as intended.


Edit2: after a fair amount of testing I discovered a potential bug (dunno whether it would be a problem or not in actuality, but better to remove it / rerandomize it than be sorry down the line) I've updated the reseeding formula in the .ips (and reupped the DL with this change).

Cheers! Venus Djinni Set

Salanewt: Updated it to provide more info that I forgot to mention.

Salanewt: I'm still trying to iron out IQ 2 but I'm pretty sure it's entirely random targeting.
October 13, 2018, 03:16:29 AM
Salanewt: Oh yeah, I posted some more info about enemy IQ.

Luna_blade: Though Momo rings a bell it seems I came here after you left
October 11, 2018, 12:49:41 AM
Fox: (If that makes sense.)
October 11, 2018, 12:48:33 AM
Fox: Yeah, I guess so.  More just saying that's a good place to get answers to GS related questions at the moment.

Crystal Sonata: I did before, but I guess I could try it again
October 11, 2018, 12:41:32 AM
Fox: Not much at the moment. This forum seems pretty quiet. Perhaps you'd be interested in joining the Discord for GSHC that seems to have more activity?
October 10, 2018, 11:16:53 PM
Crystal Sonata: Any projects going on? I need a distraction from the daily grind and I'm interested in hacking GS again.
October 10, 2018, 10:02:53 PM
Fox: Thanks, and good to see you too!
October 10, 2018, 10:02:10 PM
Fox: A few people I'm sure... Most likely the regulars of the past. Such as Atrius, Charon, Role, Salanewt....
October 10, 2018, 03:11:17 AM
Crystal Sonata: I find myself wondering who still remembers me here. Obvs you do (Good to see ya Tea)
October 10, 2018, 12:46:11 AM
Fox: On second thought, it might be because you haven't posted much as Crystal Sonata.
October 10, 2018, 12:41:12 AM
Fox: And your intro isn't that bad. - I imagine most people would say the same about theirs?
October 10, 2018, 12:39:39 AM
Fox: :O - You've been gone so long, I think I forgot you were Momo.  Interesting.

Crystal Sonata: I just revisited my dark past on here and ouch. Someone delete that introduction thread please, the cringe.
October 09, 2018, 08:26:11 AM
Crystal Sonata: Aaaaand, she re-appears yet again. My life keeps dragging me away from the internet sadly.

Luna_blade: haha oof.
