Oh,I'm so sory,because I forgot post how to install it.
1.Extract fwclaireredfield12 & fwclaireredfield22 to anyway you can find.
2.Rename*.PLD (in fwclaireredfield12 & fwclaireredfield22) to PL01.PLD
3.Found PL01.PLD in [Example:]\CAPCOM\BIOHAZARD2\Pl1\pld,Now Backup this original file.
(Because, if bug happen, it can be save back.)
4.copy which one you like to [Example:] ...\CAPCOM\BIOHAZARD2\Pl1\pld... replace file(PL01.PLD).
5.Start new game to test it.
