I don't know the rules around this next, but you might check with whoever you were getting help from before, to see if fees for court documents might be waived for you during the appeals process. The appeal on this case still impacts victims, and I do know that for people who work in the court system there is usually fee-waiver for getting documents like this. It's worth a try, because the costs can really add up. Some of these motions and briefs are hundreds of pages long.
California is actually pretty strong on victim's rights. Here is a link I found for help during the appeals process in non-DP cases, which I believe this case would fall under (apparently you can even attend oral arguments, if you are so inclined):
