I got the same issue and I somehow figured it out.
Instead of downloading and then directly putting it in your sdcard/switch, I download the 1.9.3+ from ppsspp website and put it in the switch folder, and the override the content with the package. It works fine then.
Yes, You can.
With a banned console, you can upgrade your firmware, and update your game.
You CANNOT use eShop, and CANNOT play ONLINE. Local playing is not affected.
Well, Yes, Microsoft could define their RULES, but RULES are not LAWS. All the hacking code are legal according to US LAWS. Again, nobody could sue them by any means.
Finally, I got the final file. Thanks to the author. @SimonMKWii
Things user need to notice is that, you have to ensure the PRODINFO.bin is decrypted by your BIS keys.
Not sure about other models of Pi4 but the Pi 4 B with 8GBs OCed to 2Ghz handles PSP really great except like 1 game I found and it is playable it just looks bad lol Motor Storm Arctic something or other.
I mean yeah sure but the specs are the same as a $50 model, it's just those pesky "quality of life" things driving up the price, like an actually working speaker, or buttons that don't melt, and stuff like that.
I think all in my Pi 4 was well north of 200 bucks 150ish for the Pi 4 the case the fancy cooler, then like 70 for the 500GB MicroSD then like 70 for the Xbox controller. But honestly it's a nice set up I really enjoy and to me was worth every penny. (even bought more controllers for 2 or 4 player games.) hmmm have never played any 2 player games yet
Yeah that's what I hate about the RPi, it's supposedly $30 or something but it takes an additional $200 of accessories to actually turn it into a working something.
Yeah a lot of it I consider a hobby, using Batocera I am constantly adjusting the collection adding and removing stuff, scraping the artwork. Haven't even started on some music for the theme... Also way down the road I am considering attempting to do a WiiFlow knock off lol
