I bookmarked a few useful RAM offsets for reference when programming in ASM:

$FFFFD080: Whenever you load an object you move the object number here.
$C00004: Before moving Nemesis compressed art to a0, you always move something here.
$FFFFF600: This offset is the offset that holds where you are in the Main Game Loop.
$FFFFFFF8: This offset contains which machine the Genesis is.
$FFFFFE10: This offset contains which level you're in.
$FFFFFE11: This offset contains which act you're in.
#FFFFFE20: This offset contains how many rings you have,
$FFFFFE22: This offset contains the current time.
$FFFFFE1B: This offset contains how many lives are in the lives counter.
$FFFFFE2C: This offset contains the shield value (0 = False, 1 = True)
$FFFFFE2D: This offset contains the invincibility value (0 = False, 1 = True)
$FFFFFE1B: This offset contains how many rings are in the rings counter.
$FFFFFE57: This offset contains how many emeralds you have.
$FFFFD008: Sonic's X position
$FFFFD00C: Sonic's Y position

Not much, but hey.

Take a look at this text file (by QuickMan).
http://pci.univ-lyon...0300958/RAM.txt

It contains much more informations about that (even if some aren't in it).

Also, drx has <strike>stolen</strike> borrowed it in making his RAM breakdown page.

I may as well note that a lot of that info is from Saxman's originals, with some other stuff from sources I've long since forgotten.

Wtf? That text file is a S2 RAM breakdown. Drx's guide is a S1 RAM breakdown.

QM's does have lots more info, but only 4 of mine are listed in his. Oh yeah, and QM, $FE22.w contains the time, not some unknown mysterious variable. =P

But this is just more proof that QM knows a lot more than I will ever do. I'm an idiot. >.<

Does anyone know the location of a variable that can tell you whether sonic has speedshoes or not?

$FE23.w = Clock (minutes) for player 1
$FE24.w = Clock (seconds) for player 1
$FE25.w = Clock (milliseconds) for player 1

:P

Seriously though, I wasn't aware of that when I first wrote the document (being unaware of the nature of the CLOCK).

That's actually 1/60ths of seconds, not milliseconds.
