Yesterday I spent some time trying various things with my newly acquired slim PStwo console (SCPH-77004), which I mostly use just as a networked media player. I already have two fat PS2 consoles for other needs, but yesterday I decided to try some of that stuff on the slim one as well. But I was surprised to discover some weird limitations.
I tried installing several CodeBreaker versions (hdlmod patched v9.2, v9.3 and v10) and all of them worked fine for launching DVD-R games through ESR. But none of them could work with USB devices (for Day1 codes and gamesave backups), and would not even boot correctly if any such device was connected. After checking out some cheat code sites I found that this is apparently a known bug in these CodeBreaker versions, which are incompatible with all USB devices on all slim PS2 models from SCPH-7500x and later. But I'm surprised that I never saw this fact mentioned here at psx-scene...
Some rumours (started by Pelican staff) claim that there is a CodeBreaker v10.1 which can use USB devices on all late slim PStwo models, though they also claim it is only compatible with devices from two different manufacturers (one of those being Sony). But since I could not find a single post by a user who could verify that it works at all, I'm inclined to disbelieve it.
If anyone can definitely confirm or refute the claim that v10.1 can use USB devices on PS2 models later than SCPH-7500x, and including SCPH-7700x, I'd appreciate it.
Another odd problem which has consumed a lot of my time, not just yesterday but also when I first bought the slim console, is that the memory card slots seem to work differently from each other !!! !!!
All my 8MB cards work fine in either slot, but my Datel 32MB cards do not work properly in slot 1, though they work perfectly in slot 2. I've tried this with two different consoles (both the same SCPH-77004 model) and got the same results with both of them. In slot 1 the Datel cards may occasionally function well enough to boot FMCB, or to show contents once in the browser. But trying the same operation again (like just exiting and entering the MC browser) will mostly fail even then. And yet the same MC works perfectly when inserted in slot 2.
This is another problem I never saw described, so I'd appreciate it if other users of the same PStwo model could confirm (or refute) that Datel 32MB 'Max Memory' cards there have the same problems I've seen.
That problem is especially serious when using CodeBreaker, as it forces me to use an 8MB MC in slot 1 where CodeBreaker will use up much of the space for storing the cheat database (as soon as you save even a single custom cheat, which I have to do, being a PAL user). That's bad enough for v9.2 or v9.3, both using appx 1.3MB, but it's horrible with v10 which used 1.8MB... Fortunately it's possible to get some of that space back, by deleting unwanted database entries.
