Ok, for REmake. i swear that i read somewhere that you can unlock the anti-tank rifle from dino crisis2 and i also swear that ive seen screenshots of jill holding it. but i cant find the requirements to do so anywhere. so am i just going senial with old age or am i missing something here????

You can unlock an Anti-Tank Rocket Launcher for completing the game in under three hours, insta kills anything. Don't know if it's the same one since I haven't played Dino Crisis 2 in a very long time, though it may be what you're thinking of.

You may be thinking of one of the unlockable guns from the PC version of RE1

Well thats one thing ive yet to accomplish. my quickest time was 3:05:42

So this is true? I need to try it

It the remakes version of the rocket launcher. you get it instead of the 4 chambered one from the original.

I have no idea what it looked like in Dino Crisis, but along with the infinite Samurai Edge you could unlock the infinite rocket launcher, which looked totally different from green box looking thing Brad drops at the end. This is it:
