Nice one Seth. A few other things:
Here are the addresses for the English version:
813383A8
813383AA
Here are some special other characters you can put in the text (from James S' Kingdom):
0x2A cross (used for lives for example)
0x2B coin symbol
0x2C Mario head symbol
0x2D star symbol
You can also actually make the string longer than 4 characters. Anything past 5, however, will just go behind the timer itself. For each set of 2 characters you want to add, you just move two bytes down the address. For example, the 5th and 6th character are located here on English:
813383AC
That value is normally set to 0000, because 00 is the terminating character for strings. This means if you use just 5, be sure to set 813383AC to XX00. If you use more characters, just make sure it eventually ends in 00, or else you will get a bunch of crap behind the timer. On the same note, don't try to use 00 for spaces in the text. This will just end the string early. Use 01 or something.
Example code to say "BEBOP" before the timer:
813383A8 4245
813383AA 424F
813383AC 5000
You can change the 5000 to 5001 or something to see what I meant about crap behind the timer.
James S knows a lot about strings in this game. More info can be found here:
