No prob. Bleem was made during the time when PsEmu Pro was the no. 1 free emulator. During that time when Rand (the programmer of B!) announced that there will be such an emulator that runs MDECS properly, (if I remember it correctly), even emu programmers were skeptical (MDECS in FULL COLOR??? and speed?), and said with computers (during that time 233Mhz were high end) only MDECS can be run in full speed if it was black and white. When bleem came out, it simply blasted out the opposition. Many people were praising bleem then (just as many are praising epsxe now).
You'll notice that bleem runs well even with a slow 233 Cyrix computer. For those of us with a crappy computer (mine is a 350mhz amd) bleem is the way to go. For those with faster computers epsxe is. Even still, for the games it runs well, bleem runs it well, with perfect mdecs to boot (epsxe always had those sound problems with most games I have, and I tested it with a PIII 800 Mhz, while bleem runs it well even on my old comp).
Its simply the same reason why people buy VGS before. It works well for them and they want to reward the programmers some cash.

(I'm a programmer myself, and I understand why programmers go into a fit when their child program gets pirated)
