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

Maxipotter: I have no idea who MaxiPower is I have used this user name everywhere for at least 15 years O.o   I should really get a more serious one but meh.

Fox: I wonder who Maxipotter is? Why does the name sound too similar to MaxiPower?

Fox: That would be cool to have, yes. Where the text in the ROM is uncompressed. - The huffman compression used in the gba games is not used in the nds game, so perhaps that may be one reason it wasn't done. I think it is some generic compression thingy. If someone did do it (and make the entire ROM uncompressed), perhaps I would be more inclined to work on my dark dawn editor. Hm?

KyleRunner: Could someone please create a GSTOOLKIT compatible with Dark Dawn? I'll try to translate that one to my language as well (as I did with the first two games).

Salanewt: Okay, minor announcement I guess. We just looked over some pre-release footage of GS1, and noticed that one of the unused and unlisted animations we discovered in GS2 (and GS1) plays in that footage. "Brine" is actually an early Fizz.

Atrius: There used to be where I got the battle sprites for Kraden, but that site doesn't exist any more.

Infitek: Do you know if there any custom Alex battle sprites available on the internet ?

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.
