PSEMU Pro was discontinued because of one beta tester who leaked a beta on the net.
But think about this: what would it be looking like if it had been continued?
My answer: INCREDIBLE!(that's what I think)
VGS has been bought by Sony. Connectix will stop supporting it in June. VGS had hinted about another update for VGS but nothing ever came of it.
PSEMU PRO was, as was said, destroyed by a beta tester who took it upon himself to leak the beta before the PSEMU team was ready to have it released. The sad part is that this beta tester was a personal friend of theirs and they thoght they could trust him. When he betrayed that trust, it so disgusted and hurt them that they dropped PSEMU PRO for good. But thanks to their pioneering the use of the plugin system and permission being asked for and given to use it, we have great emulators like ePSXe and Adripsx today. But, it was a very sad way fo PSEMU PRO to end up.
