Master of Monsters: Disciples of Gaia: Master of Monsters Fix

Master of Monsters: Disciples of Gaia is a little know turn based strategy RPG game for the PlayStation. One of the main reasons it's 'little known' is because the retail game shipped with game-breaking bugs making it frustrating if not unplayable.

Specifically a broken random number generator and a crash when the player reached level 100. This patch fixes those issues. Assembly file (asm) included.

Gameplay offers single player and multi-player 'versus' mode and consists of summoning monsters for battle and capturing territory to gain resources. Though the graphics and menus are a bit 'clunky' for a PS1 era game, it can offer some decent entertainment value for strategy enthusiasts.

This is for the US release of Master of Monsters Disciples of Gaia for the Playstation.

The game shipped with a couple severe bugs:

1. Its random number generator simply counted up 2 each time till reaching 100, then started over. The effect was that all actions using the random number generator went through long stretches of "sure hit" then "sure miss".

For those who don't know, number generators usually work like this: if an attack has a 75% chance of hitting, a random number is generated between 1 and 100. if that number is 75 or lower, the effects of the attack are triggered (damage animations etc). If the random number is higher than 75, the damage events are NOT triggered.

The generator was used to decide attack hits, spell hits, abnormal status effects, tower rewards, level up stat gain, monster fusion success and much more.


2. Crash when player reaches level 100. This patch sets a level cap at 99. It simply drains any experience gained after that point.


ASM FILE:
This contains the assembly code used for this fix. It can be ignored if you just want to play the game.

IMAGE TYPES:
Apply to the bin file from a bin/cue type image with a program like PPF-o-Matic. It will probably NOT work with MDF/MDS images since they include sub channel data which shifts data locations.
