thanks for the info m8 didnt know anything bout nabnab, so was worth a try haha
anyway i can confirm that the vita has the ability to output a lot of debug information via usb.
a lot of information can be gathered by patching CMA, example below:
events catched so far:
- START EVENT RECIEVE
- DATABASE CHECK
- DATABASE OPEN
- START CONNECT DEVICE
i'm still testing if the monitor mode which nabnab mentioned really can be triggered via usb, tho.
anyone who would like to join research on this let me know
