I did try and post this on the wiki fundraising page but once submitted it said I hadn't answered the captcha question, although none was asked. As you may remember I had an issue with my DIY adapter and could never get it to work. I eventually went down the GPP route and got a CronusX. Do you think the first firmware would support GPP? or will i need to start on my DIY adapter problem solving again?
GIMX firmwares can only run on the DIY USB adapter.
Sadly there probably will not be any GIMX firmware for the PS4 in a near future (Sony disabled the USB inputs).
