There are some things that we need to modify before starting this project.
Open the file called "LoM-Param.lua". You can open it using any text editor. If you open the file you will see this:
NAME_TABLE_1 = "US-PSX-LegendofMana-01.tbl" -- Name of the first table file (must be in the DIR_TABLES directory
NAME_TABLE_2 = "US-PSX-LegendofMana-02.tbl" -- Name of the second table file (must be in the DIR_TABLES directory
NAME_TABLE_MTE = "US-PSX-LegendofMana-MTE.tbl" -- Name of the table file used for insert dictionary (MTE) (must be in the DIR_TABLES directory)
NB_MTE = 16 -- Number of entries in the dictionary (MTE) - 234 should be the maximum
NEW_EXE_NAME = "LOM-ES.EXE" -- New name of the EXE in the ISO (replace the original SLUS)
PD: I have been told that is not a good idea to change the original name of the .exe file, as this file is probably used by emulators, cheaters, etc, so type the original name instead which is "SLUS_010.13".
