There is no REAL advantage of buying a slim as apposed to a phat PSP AFAIK.
The homebrew released might have different versions on different models depending on what the program is. Most of the other time, its universal for all models.
To add to that the only homebrew revisions that would need to be made would be through hardware, since all PSP's run the same firmware updates. I can't recall much of the hardware revisions in the 2000 besides of course making it slim. To affect the software their is only slight, if anything, and minimal changes.
The main reason why I got the Slim as opposed to a replacement PHAT (by upgraded I mean replaced because my old one broke) was because of the TV output which is handy for the UMD films I have but don't like watching on the console itself (I was given them).
I was only asking this because I might as well take advantage of any benefit, if there is one to certain applications.
I'd hate to tell you, but Sony's marketing technique for UMD films went down the gutter.
It was a good attempt at first, but people rely on DVD/BlueRay discs than UMD films because they are universal as opposed a lame Sony Media Discs.....
On the other hand, it is possible to have gameplay on an TV output. So if a game comes out you like and you want it on your plama screen TV or whatever your working with, you can play games on a much larger screen. (Of course with the proper cables and hardware).
I don't know much about the TV output functionality, but a good google search might help you for whatever your looking for too.
I know UMD films are essentially no more, but as I said I have loads already anyway, I also know about games, etc. on the TV which is also useful and I can use it to play converted films etc. rather than hooking up my laptop when away.
Like I said, the TV output was just what tipped me to get a slim over a PHAT. I knew what I was buying, minus the current topic.
Where I bought the console, it was only £15 for the slim over the PHAT so I thought I might as well get that (I went retail because of the warranty, needing to get the older mobo revision and I had a voucher).
The reason for this topic, to reiterate, was just to see if there was any homebrew which benefited from the extra RAM besides what I already listed (I tried Google). If there isn't, then fair enough.
I just found another plugin "FuSa" which allows for both video and game output via composite/SDTVs. I'll thank you then for leading me to this.
