HUD editing (SCORE - TIME - RINGS)

Submitted by Guifrog on May 19 2005.
This will make you able to edit things like the actions of the SCORE and the RINGS & TIME mappings when you have little time or no rings in a level, where they will be located when flashing, etc.

The format for the texts is the following:

YY NN RR GG (??) (??) (??) XX
Obs.: The (??) things have unknown action.

YY - The Y (or vertical) position on the screen
NN - How many sprites on the current object won't flash
RR - Red Flash. For this one, you can input several values, 8 per 8 in hex. Examples: if the mappings you are editing are for the TIME red flash (second frame of TIME, appears when you have little time in the level), you can input a "08" for mirroring the text while flashing, "10" for flipping, "18" for flip/mirroring, "20" to disable the flash. You can also input other values that will cause many interesting effects, like doin' all of these with flash disabled ("28", "30", "38", "40") and so on.
GG - Graphics read position. Usually "00", to read the mappings from the beginnin'.
XX - The X (horizontal) position on the screen.

Note: If you want the Time/Rings to disappear instead of flashing when Sonic or Tails have no rings or little time, you can randomicly input values for all the bytes that compose this format for hud editing, in the Time/Rings second frames ("flashing" frames, no rings/little time) offsets, of course.
