Pokémon Gold/Silver Scripting Tutorial

<p>thanks alot for such a tutorial. Can u tell a bit about flags and how they work? </p><p> </p>

Nice Tutorial :)
Seeing as there's no real script editor for second gen I might add that to the Tool I'm writing atm. But it will have low priority. Of course I'd need to find out what all the bytes mean first too ^^
But indeed a nice starting point to GSC Scripting :)

PKSV works perfectly for the second generation games, only a few commands are different, but the truth is that it works 100%

Thanks to your tutorials I learned to use pKSV

We've got all the information right here :)

Tauwasser has explained a few codes wrong. For instance codes "0A and 0B" should be swapped in terms of what they do, but apart from those small errors, that document is brilliant.

Well actually, pskv has a few bugs in it and some things could be implemented better in it as well. But it works well for the most stuff. Only things I can remember it "does" wrong are "fruittree" and some phone call command.

Not sure if you're still around or not, but flags are 16-bit values that tell, which value to check from a table that starts in ram address $D7B7.

For example, flag "2A 03" represents for "0x32A"th flag which would be in address: $D7B7 + 0x32A / 0x8

*that dividing by 0x8 comes from the fact that we have to convert the bit value to hexadecimal first before we can sum that to the start of the table ($d7b7).

Once you set a bit number / flag, "1" is written to the address where the flag "points to" and when you reset a flag, "0" is written to that same address. So flags simply point to a single bit in ram.

Thank you!!! It really looks so cool, I love 2 gen games, for me they're the best!

Ah, I know you. I've seen you on Romhacking and I watched your G/S/C tutorials on Youtube before. Planning to watch them again as it's been a while since I touched any type of ROM hacking, they were always helpful.

Am still debating on what to do for a hack. I don't want to go mad with big, grand ideas and try things that are too complex in a beginner hack, but it's also pointless if I'm not learning new hacking techniques. Gen 2 deserves more hacks.

Ah thank you for this amazing tutorial, definitely bookmarking this. I grew up playing gen II so my next hack is going to be a G/S/C game! Stay awesome!
