Almost one year ago I wrote an experimental post about compiling HL1 maps on Android TV-box (instead, you can use any Android smartphone too) on my personal website. And I think that may be pretty interesting for you to read or to reproduce my experiment.

Interesting. I guess this should work with standard GoldSource VHLT?
No, without modifications at least. For this stuff I ported map compilers sources to support ARM and 64-bit architectures

I'm comparing that to my experience, LOL :D Moddb.com
VIS may works too long in case of there is a lot of detalized geometry and it's not wrapped with func_detail entity.
