I got tired of fiddling around with the mouse to load diskette images in my Vice/X64 setup, and hacked together a small web application to do it from the smartphone.
In short, it presents the contents of a database of all your software in the phone browser and allows remote start of any C64 program.
The design is based on IUI, http://iui-js.org, and the remote mechanism relies on the remote monitor in X64, which required some patches to work fully, see the README in the source for details.
Source code, a few very short php scripts + some bash code, is available for the brave at Bitbucket: https://bitbucket.org/kwiklund/vice-x64-web-launcher, but don’t expect any fast support, it is in the 80% working state, which means that I’m likely to lose interest in it really soon…
