MESS BIOS in the wrong place

[SpudsMcToole]

Having begun to get to grips with AdvMESS, I thought I'd see if its Dragon 32 emulation was any better than the rather nasty implementation in Xroar.

I changed my EMULATORS.CFG file to this:

advmess = "/opt/retropie/emulators/advmame/bin/advmess dragon32 -cfg /opt/retropie/configs/dragon32/advmess.rc -floppy %ROM%"
default = "advmess"

(Not sure what to put instead of "floppy", since it's using tape files.)

I've got the BIOS (d32.rom) in the /opt/retropie/configs/mame-advmame/rom folder with the other MESS BIOS files, both raw and zipped, and I've also got copies in the /opt/retropie/configs/dragon32 folder and the /home/pi/RetroPie/roms/dragon32 folder for good measure.

But when I try to run anything, I get dumped straight back to ES with this error log:

Parameters: 
Executing: /opt/retropie/emulators/advmame/bin/advmess dragon32 -cfg /opt/retropie/configs/dragon32/advmess.rc -floppy "/home/pi/RetroPie/roms/dragon32/Donkey King (1983)(Microdeal).cas"

Anyone know where I'm going wrong here? Where else might it be looking?

I have managed to get Dragon32 working in MESS.
My emulators.cfg looks like this

default = "advmess"
advmess = "/opt/retropie/emulators/advmame/bin/advmess dragon32 -cfg /opt/retropie/configs/mame-advmame/dragon32.rc -cassette %ROM%"

That goes in
/opt/retropie/configs/dragon32

along with a standard advmess.rc
Make a copy and name it dragon32.rc, and put it in

/opt/retropie/configs/mame-advmame

roms go in
/home/pi/RetroPie/roms/mame-advmame/advmess/rom

And they're named
dragon32.zip -- contains d32.rom (crc=E3879310), and ddos10.rom (crc=B44536F6)
dragon64.zip -- contains d64_1.rom (crc=60A4634C), d64_2.rom (crc=17893A42), and ddos10.rom (crc=B44536F6)
dragon_fdc.zip -- contains ddos10.rom (crc=B44536F6)

After selecting a .cas file and running, you are at the green Dragon home screen. Type CLOAD - for Basic Games, and CLOADM for Machine code games.
I have been successful in running many games. They load in real-time, so you need to wait for often a few minutes. There is a blue flashing square in the top left corner, this gives you a visual cue for the tape loading.
Definitely, a step up from xoar. I noticed the sound was much better.

@John_RM_70 Aha! The key was renaming the BIOS file to dragon32.zip! (From d32.zip.) Many many thanks for that. Now I have the Dragon OS screen showing, if I could only figure out why the A key won't work (leaving me only able to type "CLODM") I'd be sorted...
