Classic on webOS 2.0 made possible thanks to webOS 1.4.5 Doctor, homebrew ingenuity
PreCentral forum member and homebrew developer Arthur Thornton just earned himself a page in our book of awesome people: he figured out the so easy a caveman with Terminal access could do it method to getting Classic to work on webOS 2.0. It’s simple in concept and execution: extract the Palm OS ROM from the webOS 1.4.5 Doctor, and then load it onto your webOS 2.0 device. Tada, Classic instantly works.
It seems to be as simple as that, which makes us wonder why Palm decided to drop the Palm OS ROM from webOS 2.0 and shaft MotionApps in the process. The only thing the Palm OS ROM does is take up space (not a lot, it is Palm OS after all) and wait for Classic to launch it, so why cut it out. Unless Palm is pulling an Apple (dropping the floppy drive) and forcing developers and users to move on from old tech. Full instructions after the break.
