This is a small thing I wrote some time ago to convert your existing .pat files to Regen cheat files. Somebody asked me for this so I thought I should put it up here for everyone. You can download it from here.
One thing to note that multi code cheats should be like this:
Code: Select all
XXXX-XXXX Become invincible \
YYYY-YYYY Become invincible \
ZZZZ-ZZZZ Become invincible /
You can also combine GameGenie and PAR in multi code cheats.
