Virus TI - early puzzlements

[suzzymackenzie]

I have had my TI for a few weeks now and really enjoying the discovery. Still excited about the pulsing logo

Just a few initial queries, if I may:

ARP patterns - it seems the 64 presets are not visible in the VirusControl grid in the same way that User patterns are. Seems a shame you can't take them and edit them. Are they in fact non-editable?

Spare ROM banks - can't write to them by normal means, so this seems to mean that saving new patches onto the Virus has to be in the few remaining RAM patches at the end of the preset list, and after that it's hack away unwanted presets and replace them with my own. Am I missing something here?

In the display, each patch has a little symbol like [||| ] or [|||||]. Wazzat?
