This is a sub-page of Vagrant Story.
All address ranges and file sizes are specific to the US version of Vagrant Story. There are a couple of missing executables for the menu interface. MENUA.PRG is an empty file whilst MENU6.PRG is missing entirely. Most of the executables are partitioned into three sections. The first section is data, followed by code, which is followed by more data. The root executable is not partitioned as cleanly as the rest of the executables.
The games executables are only loaded as and when needed. Thus many executabels share RAM address ranges. The first executable to be loaded is the psx exe file. This would be SLUS_010.40 for the North American version. This file contains libraries, such as PsyQ. This file remains in memory throughout runtime. The main executable is BATTLE.PRG, this executable is the game engine. It shares an address range with TITLE.PRG and ENDING.PRG. The menu interface is controlled by various executables. The main menu is controlled by MAINMENU.PRG which shares an address range with INITBTL.PRG. All of the sub menus have an executable associated with them. They are all loaded to the same address and once finished they are left there until there is a need to load a new PRG file.
