Hi, I have the firmware v3.03, which I installed to play Prince of f*rking persia before I discovered that this firmware was actually crap. Anyways. It's not like I didn't have a chance to get out of it, I took my psp back to sony following a glitch and they sent me a new one... and well I reinstalled v3.03 coz I didn't know better of course. Now you see that I am a bit reluctant to install the homewares, because if the psp dies on me again with this on it, the warranty won't apply. My issue with 3.03 is that it can't play video files full size. You can 't play 480x277.. I am not even sure the higher official firmware are ok. The webpage from sony v3.30 says: The following types of files can now be played in the "VIDEO" folder. – MPEG-4/H.264 AVC Main Profile (AVC CABAC) video files of the following sizes: 720 X 480, 352 X 480, or 480 X 272 * Depending on the data type, some files cannot be played. so with a nice "depending on the the datatype it just won't work.."! wll they are all mp4.. so... they must mean the size (?). The upgrades v3.40 and 3.51 don't mention anything about that. I forgot to mention that I encode the mp4 in ubuntu using pspvc. If I wanted a small size I would have bought a ipod.. Does anyone know if the higher firmware versions work better ? If I go on installing homewares, then if my psp dies due to hardware problems can I like downgrade to 1.5 then install the firware from 3.03 from my prince of percia game and then pretend it was always like that ? what is the big plus of the homewares ? If I have a homeware can I play any umd ? what if the umd requires a higher firmware let say 3.6 can I install it on top of the homeware ? And on a purely hypothetical basis, and more like a case study, lets imaging someone comes up with a iso of a umd game. Let say that when you put the umd in it asks you to update your firmware just like prince of persia asked me. If one where to play the iso from the memory stick (because he doesn't want to walk around with umds) would the game ask for the update too ? then can you "just" find a corresponding homewares ? By the way do homeware numbers correspond to the sony ones apart from the restrictions? Like if 3.6 were to add a pdf reader, would homeware 3.6 contain a pdf reader too ? Ok I am done bother you, Thank you for your time. [aad-on] sorry I forgot to ask.. is it possible to upgrade to any particular version rather than the latest one provided by sony ? so that that if I don't find gta and can do it with luminus ?
