Well spent hours trying to finish menu player. Constant banging my head against the wall.
Until I noticed there was a command not in the sample to play more than one mp3.
Basically, when you play a track ME CPU goes into play only mode. Meaning, any playlist is ignored and it plays same track over and over.

Now thats sorted, it plays perfectly through on the fly generated playlist. It now scans the MP3 folder and then creates a playlist from its contents.
However, PSP can't handle MP3 above 128k bit rate. So I wrote a script to re-enode my MP3 folder (overwriting old ones). It worked great, every MP3 now plays.

It was a bit late to do more, so I left it there. I want to add final bit, which is random MP3 selection from generated playlist. I do have some other ideas to do, however, I feel I'm in feature creep territory.

AFAIK the JIT bug was a MacOS ARM64 thing 

This is not a pure emulator.  It's a Hardware Abstraction Layer with a MC68K emulator

Implemented MP3 pausing and resuming.
Working on scan and auto play.

I'm at risk of falling down rabbit hole. Aready side tracking myself.
Been looking at ways to improve memory allocation. More specifically, reverse allocating available.
It cant be done on PSP (exactly like on Amiga), however we can simulate it, allocate small stuff low and caches high (only Paula and MP3 at moment).
Can also get UAE to use it and allocate in same way.

Think its better for me to note ideas down and revisit them, after improving rest of backend and getting speed up, via offloading more to ME, like blitter and copper.
Biggest slow downs are also in IO access, i.e. demo's State of art constantly loads from floppy, this is were the demo nose dives.

Also havo consider PSP-1000. I'm currently using my Go. PSP-1000 only has 24MB usable mem, Go (like all other PSP's after 1000 have 52MB usable mem).
Adding loads of caches, will limit 1000's usable ram, So setting Amiga ram to say Chip 2MB, Slow 1.5MB, z2 8MB and z3 8MB cause it to crash. Go doesnt care, it eats the entire user ram and just keeps going into extra 32MB hidden cache mem.

Hello,

About the kickstart version: you'll need one that supports drives bigger than 4GB, or you won't be able to access all partitions of AGS. It will boot, but won't access the games 
So original kickstart ROM 3.0 or 3.1 won't do, you will need either a newer 3.2.x, or a modified 3.1 with a fixed scsi.device .

If you have an accelerator with MapROM functionality (like a Blizzard IV), then you can keep the original ROM. This requires modifying the AGS image in WinUAE: you need to modify its startup sequence to make it load the new kickstart from a file and reboot.

And as for a PCMCIA IDE adapter, the big disadvantage is that you cannot boot from it, you will need to prepare a floppy for that.

Cheers!
