When human skills are just not enough

Game Resources / SNES / 7th Saga

The purpose of this page is to document information about the RPG 7th Saga.

This article concentrates on information that would be useful in the making of tool-assisted speedruns.

Random Number Generator

The random number generator is located at 7E006C and 7E006E. It increments by (RNG*0x383) mod 65536

Overworld Incrementation

The random number generator increments multiple times per frame on the overworld to determine enemy movement patterns. The amount of enemies currently on the screen tends to correlate to the amount of incrementations of the RNG.

Dungeon Battle Incrementation

In a dungeon battle, the RNG will only increment due to character and enemy actions. This makes it very difficult to manipulate favorable outcomes, because the battle is nearly predetermined from the RNG it is entered on. Choosing a good starting point is extremely important.

Overworld Battle Incrementation

In an overworld battle, an additional source of incrementation exists. Once every 1-2 seconds, the RNG will be called in order to perform random movement of the water on the overworld.

-inf to -42 2%
-41 to -12 5%

Vacuum and Effect Spells

The game does an agility check and then a success check. The success check follows the following formula:

PercentChanceOfResist = DefenderResistanceStat - MagicResult

MagicCalc = 256*(AttackerMagic - DefenderMagic)/AttackerMagic

If (MagicCalc > DefenderResistance) then MagicResult = 0 else MagicResult = MagicCalc

This creates strange possibilities, for example when Lejes is wearing most armors and the ring, his DefenderResistanceStat for vacuum is 20 + 95 = 115. If you then go up against Doros (Magic 130) with Magic 72, then the formula creates a counterintuitive result as follows:

PercentChanceOfResist = 115 - 256*(130 - 72)/130 = 1 , and you would likely get hit by vacuum. Equipping the Fire or Ice cloak as armor with the ring may be better in this case, but it needs evaluated on a case by case basis.

Lux's Infinite Stat Boost Glitch

In the past, if Lux is in the party, he is able to receive a stat boost for 30 HP, 30 MP, and 20 of each other stat. During the cutscene for this, the player is able to walk 4 steps. The game does not check for collisions during these steps, so Lux can either walk out of bounds or up the stairs. If Lux walks up the stairs right as the dialog box appears, he receives the stat boost, but the flag for getting a stat boost is not set. Lux can receive multiple stat boosts through this method until his stats are maximized.
