These Nightmare modules will let you change the delay for the various text speed options. Lower delay = faster text. 0x7F is the slowest you can make it since values greater than 0x7F are treated as max speed.

Default delay
FE6: Slow = 8, Normal = 4, Fast = 1, Max = 0
FE7: Slow = 9, Normal = 5, Fast = 2, Max = 0
FE8: Slow = 8, Normal = 4, Fast = 1, Max = 0
Personally, I think FE7’s Fast setting is too slow and I don’t like how the Max setting makes text appear instantly. Changing the Fast setting to 1 delay like FE6/FE8 is much better.
Out of curiosity, I decided to check FE7J and it uses 08/04/01/00 just like FE6/FE8. So, the slowing down of text speed was a localization change.
