[Other] Expanding Pokedex

[Mickey`]

Hi,

I tried to expand the dex on a French ROM. I followed this tutorial but at the end, Pokemon above #386 are called "?", have the "NORMAL" type, and seem to crash. I tried to switch Deoxys and a new mon, but the result is the same :

Does someone know how to fix it ?


Another question : does the game use flags between 0xF000 and 0xFFFF in some routines ? (I know it's not safe to use these flags for example in a script ;))


Thanks !

Spoiler:

At x1025ec, you'll find a byte. This byte times eight is the amount of memory allocated for the pokedex.
If you have less than 510 mons, replace the byte with 1/2 your dex length.
If you have less than 1020 mons, set it to 1/4 your dex length and put 40 01 at x1025EE.
If you have more than 1020 mons, you should probably rethink what you're doing since 4-digit numbers aren't going to get along with the FR interface unless you do adjustments outside the scope of this tutorial.

At x103920, put the number of dex entries you have minus one.
If this is more than what got malloc'd, the game will crash.

At x43220, put 00 00.
Your dex should now load the full length:

If it locks up, make sure every entry maps to something in dex ordering!

I'm going to guess that a few addresses are different for the French FR ROM. I'm also going nto guess that the part you may have messed up on is the one above...

As for your second question, I think it has something to do with the fact that the flags after a certain point start to overlap with the vars and it's just a mess to try to work out.

Yeah, of course, offsets are different. But I think I correctly wrote these data...

1025ec > 102900 (French)

I want 700 Pokemon, so 700/4 = 175 = $AF, and I write AF204001 at 0x102900, right ?

103920 > 103C34

43220 > 430F8

I can't find the problem.


Okay for the flags. In fact, I wrote a new routine of the flag decrypter/setter/clearer, which allows to use flag between 0xF000 and 0xFFFF, using a new part of the memory.

Maybe this observation will help you :

On the main page of the dex, mons above #386 are not counted in the "seen number" and "caught number".
