I took a look at the text speed issue using shutterbug2000's code and tried to make a modified version to increase the text speed.
Using a tweak (which is not perfect), we can have a roughly 2x, 4x or 8x faster text speed.
Here are the cheat codes (hopefully it works):
[EU Text Speed]
00279D68 EA000007
00279D6C E1A00000
00279D70 E317000#
00279D78 02855001
00279D7C 0BFC9B18
00279D94 CAFFFFF5
[US Text Speed]
00278F98 EA000007
00278F9C E1A00000
00278FA0 E317000#
00278FA8 02855001
00278FAC 0BFC9E20
00278FC4 CAFFFFF5
Replace # by:
3 for 2x
7 for 4x
F for 8x
Well, in fact 2 will work the same as 3 considering how the cheat works, and in general the first bit for that value does not change anything (so 7 works the same as 6 and F the same as E)
