Hello guys! This is my first post and maybe it's in the wrong place, sorry.
I've been trying for a few months to pass the protection of a specific game SLPS 02220 - Rockman 1 Complete Works (J) but without success.

There is the gameshark code that allows you to pass the protection:
D006C92A 1040
8006C92A 1000

D006D066 1040
8006D066 1000

I would like to know if there is any way to find the modchip check routine and change it to ignore the check.
Or if someone can do it for me please.

Thanks guys!

use lct.exe on a LC protected psx game exe
this will spit out a file named patchdata.txt

it also then include the address that need to be patched...
looks like this :
