Since the new HP Prime OS (version 10077) had serious issues with RAM management, often causing data corruption when sending large files to the calculator, mViewer GX2 has been released, now using applications instead of programs, and it's fully compatible with the new firmware!

mViewer GX2 is an online tool that can convert PDF and image files into calculator pictures for multiple models. This can be handy if you want to read documents on your calculator or stock large images. The TI-68K, Nspire, 83+/84+/C, HP Prime, Casio fx-CP400, fx-CG10/20 and 9750gII/9860g series are also supported.
As you will see in this video, the main drawback of this new version is that each document is split into multiple pages, meaning that your application screen will be filled with hundreds of icons (*pokes
@timwessman about adding folder support like on the TI-Nspire CX*), but mViewer GX2 allows you to navigate internally from one page to another, so browsing large documents is still easy.

Looks nice! I am drawn back by having a cluttered app screen but it runs really smoothly.
