All trainers for a game are written after eachother. This string may be up to 30 characters. There is no space between the 'N' and the string. Emulator authors can use these strings to set up the selection entries. The following lines, up to the next 'N' or 'Z' hold the POKEs to be applied for this specific trainer.
All values are decimal, separation is done by one or more spaces.
There theoretically is no space between the line tag and the field. However, since the value is never larger than 8, you will always see 2 spaces in front of the . If it is 256, a requester should pop up where the user can enter a value. Normally, when applying a POKE, the original value can be read from the address. Sometimes however, games as found on the internet are already POKEd, so the original value can not be read.
