Ok! It's the first ZXB menu I'm going to include in an AGD game (and probably the first attempt ever). Just a thought... so I cannot include a not-relocatable file.
An AGD project isn't relocatable; the AGD saved block starts always below 32000 but it needs to be called exactly at 32000 to run. So I'll have something like...

Code:
... RANDOMIZE USR @agd_block ... agd_block: ASM #incbin "31018,26806_game.bin" END ASM
...and two problems rise: how can I tell ZXB to start the bin from 32000, and can it work if it isn't relocatable?!

Probably something like

Code:
ORG <low address>
GOTO start_of_program
ORG 32000
ASM
incbin "file"
END ASM
:start_of_program

Assuming you want your zxb code after the binary. Before will take some juggling to be sure it all works. I'd love to have a better memory map feature (I'd kill for an emulator with a live zoom in of memory accesses, so I can see where code is hanging out most...)
