I want too do some research into stuff like widgets, older XMB stuff. Really I would like debug output and ftp access etc on lower fw like v1.00, 2.80 , 3.00 etc. what are the chances? Has anyone ever made pre 3.41 CFW? Should I convert to DEX and use old DEX FW for research? Can I use MFW builder on 1.00 etc?
