Is there a way to patch moonlight to get the L3 and L3 working with ds3 and ds4 on ps vita 1000?

[d3m3vilurr]

theoretically, yes this patch can support ds3 and ds4.
but ds4vita (might be ds3vita either) have a little problem,
for example, xerpi want connecting multiple controllers, and I also agree that.

problem is, it's too big job (might be we can merge ds3 and ds4 feature, but..)
and I haven't free time anymore.

There already is ds3vita and ds4vita MERGED TOGETHER!
