The saved games data are in the files STATEx.DAT where x is 1 thru
5 and represent the five save game slots in the game.
Hex address 4EE5 contains the amount of player energy. Hex 00 is max.
Hex address 4B7C contains the number of shots for weapon 1. Hex
address 4B7D contains the number of shots for weapon 2. Hex address
4B7E contains the number of shots for weapon 3. Hex address 4B7F
contains the number of shots for weapon 4. Hex address 4B80 contains
the number of shots for weapon 5 (reset to 00 at beginning of every
new level).
99 shots is the max amount the game allows for the weapons, so hex 63
thru hex FF will all result in 99 shots, but hex 63 should be used
because if more of the ammo for a weapon is picked up, it still adds
to the value. So for example, if hex FF is used and ammo is picked up,
the value will wrap around to 00 and then up from there.
Hex address 4B8B contains the number of shots for the robot's weapon.
Unlike the regular weapons, this one seems to give the number of shots
for whatever value is entered there. Still, hex FF or values near hex
FF should not be used.
Hex address 4F22 begins the codes for the inventory items. Every other
byte contains a code for an inventory item and continues until the
hex value at address 4FEA has been reached. So, if there is a hex 04
at address 4FEA, then address 4F22, 4F24, 4F26, and 4F28 will be enabled.
The following list shows the codes:
The maximum number of inventory items is 100 (hex 64), but since the
game adds picked up items at the end and scrolling thru the items
doesn't wrap around from 1 to 100, it would take a long time to find
the new items to use.
