After nearly a year without updates, PlayStation 2 emulator PCSX2 has received two new versions in a week. Version 0.9.6 was updated to perform better in OS X Lion. Then 0.9.7 Alpha was released a few days later. Zedr0n included side-by-side screenshot comparisons to showcase the visual improvements between 0.9.6 and 0.9.7. You can get it, and check out the screenshots, at the PCSX2 for Mac website. As with all alpha software, proceed with caution.

MacScene regular seanstar has released new software for the NES Power Glove—more than 20 years since the ill-fated contraption was mercilessly retired. NESGlovPhone lets you perform music in real-time, on an actual NES, using the Mattel Power Glove to interact with the NES sound chip. It offers a "reasonably intuitive musical interface" and multiple modes of interaction. So it turns out it wasn't an April Fools joke. If you have a working Power Glove, NES, and devcart, get your copy at the Psych Software website.

There are changes afoot in the world of personal computing; Lion may well be both a beginning and an end. Check out John Siracusa's incredible 19-page review on Ars Technica for a complete breakdown

As always with major system upgrades, due caution is advised -- backup your system, research app compatibility, and be prepared for problems. Many older emulators will likely no longer work, as Lion drops PowerPC support altogether. Richard Bannister notes that all current releases of his emulators and other programs are "believed to be compatible," with the sole exception of audio editor Cacophony. Many others, as you'll see, have put out updates to address Lion compatibility.
