You're welcome. However, I don't quite understand this code fragment:
if (plain[0] & 0x80) {
// PPM checks here.
if (!(plain[2] & 0x20) || // Reset bit must be set
(plain[2] & 0xc0) || // MaxOrder must be < 64
(plain[3] & 0x80)) // MaxMB must be < 128
goto bailOut;
Reset bit is placed in plain[0], isn't it? Why you're using plain[2]?
