Re: IRION (Exerion) PCB found - possibly Exerion PROTOTYPE ?

The CPU roms at least, appear to be bad. Can you try dumping them again?

Robert,
I have re-read all 6 eproms.

First time I read them with a TL866 which produced errors again when I tried to re-dump today.
So I re-read all 6 eproms with my Dataman which is much more reliable.

I have burnt eproms 2,3 and 4 and tried in the pcb and the game worked flawleswsly, so you can be sure the dump works this time !

Please see attached .zip file.

any help you need let me know ...
Michael

OK thanks, that looks better - and it runs.

I've added it to MAME, but there;s a priority error between the ships and the landscape, I'll let another team member fix that.
