I had a Mister Pi delivered last week, I previously purchased a QMTech a few months back but returned it as I didn't feel it worked for me as I discussed in this thread.
In the interim I'd been watching and reading up a lot more about Mister and wanted to give it a another try now I'm better informed, in particular I wanted to try out stuff like Amiga Vision.
Mister Pi was available and in stock, I ordered on 1st September and was delivered 11th September which was pretty quick.
My overall experience has been very positive but there were a few issues I wanted to call out.
Issue 1. Warped bottom USB hub
The USB hub board appears to be somewhat bent, it's not entirely flat so USB ports 3 and 6 (the middle ones) are difficult to use and inserting a device is more problematic than it should be.
Issue 2. Warped bottom case (No base stand-offs)
Some of the solder blobs under the USB hub are quite large, the bottom case plate was screwed in tight which was bending the case due to the solder, I've had to loosen the screws quite a lot to reduce the bend and have a flatter base. Really there needs to be some stand-offs between the bottom USB board and the case, I believe the QMTech Mister had this but can't recall for sure.
Issue 3. Buttons not working
I was having trouble getting any of the Reset, OSD or User buttons to work with the plastic extensions which allow these to protrude from the case. On closer inspection the buttons had each been glued down with a little pad which meant there wasn't enough travel to allow the button to press down. I removed the glue pads and the Reset and OSD buttons now work but the User one still doesn't. It appears the plastic button extension is slightly different, probably a slight difference in manufacturing as if I try using it on another button like Reset or OSD it also does not work.
I don't really use any of the physical buttons so not a massive deal but I'll likely look for a better case in the future which I'd assume would come with replacements anyway, the case and USB hub warping issues were disappointing but all is working.
Adjusting to not having save states (for most systems) or rewind is definitely going to take some time.
I actually completed Streets or Rage 2 this afternoon, I've finished it multiple times in the past but first time for a while as couldn't save progress so I had to finish it in the one sitting which won't always be helpful when the kids are around but might make me more selective over what I play and stick with a game instead of jumping around so much.
One thing I only saw recently was TapTo (now known as Zaparoo) which I didn't really see the point of originally, but oh man this looks so cool... for anyone not in the know you can use NFC cards to launch a game.
I know that doesn't sound very impressive but I've seen people print there own vinyl card stickers like below.
People have even created their own little ejectable nfc drives (like an old floppy drive) which really appeals to me and sounds like a fun project.
