MPU emulation does not work properly with some games

[vicokoby]

In release 1.5 the feature was added: MPU port emulation if BLASTER variable contains P=xxx
So I added the variable:
BLASTER=A220 I7 D1 H5 T6 P330
before running vsbhda, but for some reason the game Charlie The Duck is using SoundBlaster instead of MPU401.
This game by default runs with MPU401 if it is available.

Actual Result

Expected Result

MPU emulation does not work here; I had it especially dealt with in my fork.
