"Contra: Hard Corps" is one of my favorite Genesis titles. Despite that, I am not a fan of the changes made for the western release which made an already difficult game next to impossible to beat. I strongly recommend combining this patch alongside the "3 Hit Point" patch. With this, you'll get an experience that's identical to playing the JP version and frankly the experience we westerners SHOULD have gotten.

Now, if you're thinking of combining this hack alongside "3 Hit Points", just follow these steps:

Step 1: Apply "3 Hit Points" mod

Step 2: Apply this patch on top of the modified ROM

Step 3: Fix checksum (To prevent the "red screen of death" when booting up the game)
