I thought this was pretty neat and worth posting for any person that wants to change the game's story significantly to where the game would star another character (or at least start the game as someone who is not Cecil.)
$00/92D6 BF 00 A9 0F LDA $0FA900,x[$0F:A900] A:0001 X:0000 Y:0000 P:envMxdIZC - Load starting character's stats from this point.
All you need to do is add 20 until you get the stats (including character ID) of the character you want to start the game as. This was originally gotten around before by changing Cecil's Class, but changing the starting point of the stats themselves lends a bit more legitimacy to the proceedings, so to speak.
In ROM this is located at 0x14D6.
In addition to this closeby is the calculating of the default Critical hit dealings and "steal prevention" (I am now under the impression that these never naturally change when leveling)
$00/92E7 BF 00 A9 0F LDA $0FA900,x[$0F:A916] A:0014 X:0016 Y:0002 P:eNvMxdIzc - Load the 14, 15, 16th bytes of the the default data and load it into 102D, 2E, 2F.
ROM - 14E7
And finally...
$00/92F8 BF 00 A9 0F LDA $0FA900,x[$0F:A91E] A:0063 X:001E Y:0007 P:eNvMxdIzc - Loads bytes 17 - 1F into character stats starting at 1037 (Current EXP)
ROM - 14F8
$00/E67D BF 00 AB 0F LDA $0FAB00,x[$0F:AB05] A:0001 X:0005 Y:0005 P:envMxdIzC - Load Starting Equipment. (Every 7 bytes is a set of a character's equipment)
ROM - 687D
And let's try and change the starting event, it is Event 10 strangely enough so finding this will be a bit tricky, likely. As it has never been looked for...
Ah! And finally found it! This is located at...
8081 in LoROM (Thank you Dragonsbrethren for the lead in the default items topic)
$00/8081 A9 10 LDA #$10 A:0081 X:21E0 Y:00F0 P:eNVMxdizC - Add 10 to A (Starting Events)
$00/8083 20 63 DF JSR $DF63 [$00:DF63] A:0010 X:21E0 Y:00F0 P:enVMxdizC - Jump to Subroutine (Event Dealings)
In Rom this is at...
281 - A9 10 - Starting Event.
This is Exceptionally useful when testing your hack and you don't want to have to rebuild your event library every single time you want to play a normal game. So you no longer need to destroy the main event and (granted there's a Load Map command within) can start the game from any point.
So there you go. This is the way to switch the main character in a more legitimate way than kicking Cecil out of the party or changing Cecil's class alone and finally for testing you no longer are confined in starting at Event 10, but may start the game where ever there is a Load Map function.
