What about disassembling the "loader" firmware code to figure it out? Too
much work just to know that?

Maybe the file is overlaid
Maybe we don't know about the addressing system properly
Maybe some of it lives in ROM
errrr, that's all I can come up with for now
Ok, i thought for the fun of it, i would run some of the firmware's original
ap files through loadram.
unable to run tester.ap i tried music.ap (it is a 65k file) when i run it in
loadram i get this:
found 4 busses
device_open(): device found
Running the program...
Loading data to send to second stage loader...
Files >64K don't fit in the z80 address space, silly.
Uploading second binary...
Error sending: No error
How can this be, the player is using an ap bigger than the ram can
