Hello Fellow Gamers. From Mark Rein
HHHmmmm...let's do some math.
GEARS Of War 6.43 GB full game with default maps.
Map pack 1 is 99mb & Map pack 2 is 230MB.
Total size of all maps & full game is 6.76GB
A full DVD9 is 8.58GB. So the available space is 1.82GB
4 maps in Gears = 230MB
So in theory 4/x = 230MB/1.82GB x = 31.6 MAPS!!!
Now that's a lot of Maps for Gears. If they use the same engine & programming technique, then the amount of maps shouldn't be that big of a deal to fit on a DVD9.
Sorry Mark, I just had to call you out on that particular remark about the maps for Gears. They all could've fit on a standard DVD9 with room to spare. So.. please, come up with something better than that.
As you should know the maximum XBox360 DVD size is fixed.
You should be familiar with a parameter: LayerBreak=1913760
Ok, LayerBreak is the sector number where the head move from layer 0 to layer 1 and start writing backward (Opposite Track Path).
You should know also that a DVD sector is 2048 bytes so each layer holds up to 3919380480 bytes, or 7838760960 bytes total (7475,625 MB).
Well, now you've to subtract the first track size (you know, the one with the "dancing circles" in DVD Video format) twice (because that's unused on layer 1 too).
What you get back (minus something for XDVD structure, minus something for security placehold, if they still exist on XBox360) is the actual maximum DVD size.
You know, it's more like 7,05 Gb than 8,58 Gb.
