It was known that a few people were able to use the TN-V eCFW on firmwares 3.3x, but those were only a hand full of people.
How about you? Would you like to run the TN-V11 eCFW on your firmwares 3.3x PS Vita (VitaTV)?
It looks like that Qwikrazor has released an unofficial port of the TN-V11 eCFW for the PS Vita firmware 3.3x (3.30, 3.35, 3.36).
This shortens the gap of firmwares that are unable to use the TN-V eCFW to pretty much zero.
Qwikrazor’s unofficial port of the TN-V11 eCFW has most of the TN-V features available (PSP ISO playback, Homebrew & Plugin support, PS1 sound support!), but it is worth to mention that a few things are broken (PSN access, due to it still being based on PSP FW 6.60, instead of 6.61, SenseMe doesn’t work, etc).
But in the end that should not matter, should it?
If you are a fan of the PSP XMB, and you are currently running an firmware 3.3x eCFW on your PS Vita, VitaTV or PS TV, then you should be able to get yourself the TN-V11 eCFW.
The two main advantages of TN-V11, compared to the ARK-2 eCFW, are the PSP XMB (arguable – some people like it, some don’t), and the partial sound support for PS1 titles.
For those of you that are currently on firmware 3.50, don’t worry! – Qwikrazor has said that it should be possible to use it on firmware 3.50 as well, as long as you take a good look at (and modify) the TN.BIN file.
