PKM File Fields
PKM files have been ripped from saved and traded online for roughly the last 5 years or so by players. Pulling them out of games is very easy and makes trading or giving out pokemon to friends a simple task. When GameFreak needs to get or set specific data for a pokemon, they do it using a switch statement and a series of fields. They do it like so:
typedef enum{
PID,
field2,
field3,
field4,
checksum,
species,
item,
tidsid,
exp,
happiness,
-and so forth-
} PKMField;
When they need to write data to the pkm file, they use this function:
void setPKMStat(void* pPKM, PKMField field, int data)
and when they need to retrieve data from a PKM file, they use this:
PKMField getPKMStat(void* pPKM, PKMField field, int data)
(data is basically always 0 in the "get" function)
The switch statements for these functions are large. In gen 3 they used 2 switches, one for party data and one for box data. In gens 4 and 5 they switched to a single massive switch that can retrieve anything. In B2W2 a PKM file has 179 fields. In BW PKM files had 175 fields.
The following is a partial list of field values for these functions: (all are in hexadecimal)
