To load different levels change to the First Samurai directory and instead of typing: SAMURAI to start type the following:

SAMVGA1 for level 1 without the introduction
SAMVGA2 for level 5 without the introduction
SAMVGA3 for level 6 without the introduction
SAMVGA4 for level 9 without the introduction

Give yourself infinite power by using a Hex editor to edit the SAMURAI.EXE file. Find 8B 87 96 2B C6 and replace the figures with 8B 87 96 44 90
