The problem with Squirm is simple: the game uses (reads) , and in a few places ($2900-$2A00) to generate pseudo-random numbers. These registers are not emulated correctly. The big problem seems to be the two lowest bits of , it probably always returns zero - hence to change in direction. If you change that line in the game's code, they start moving...
I haven't looked into Dizzy yet. One big inconvenience: opening D64 files. You have to attach them, and then change the drive to D64 file... This takes way too many steps. First of all, you could probably use ALT+8 as a shortcut for attaching a D64 image (most other emus use that key), and the drive mode should automatically switch to D64 file.
