I didn’t grow up with this game, as a matter of fact. However, unlike the the 1st Contra on NES (which I *did* play as a kid back then, but not as much compared to what I normally played), that game had the 30 lives code, which made the one-hit deaths easier to deal with (although I still sucked at the game). However, the NA version (PAL too) of Contra III left it out and a few other stuff from the original Japanese release. So if you suck at these games like I do, this is the hack to restore the 30 lives code and a few other nifty stuff. (Although the well-known Konami code is not how you will get 30 lives. Do a hadouken and press start on the cursor being on options) And yes, this WILL be compatible with the SA-1 hack as well (patch the restoration AFTER the SA-1 hack). Works wonders on the FXPAK Pro too, in tandem. Pretty neat.
