Thanks, guys.
It (should) works on NTSC or PAL (with 32K) although I don't have a real NTSC machine to test it on. Yes, I realised later about going up the ladder but I played the Revision F on MAME which does allow it. I may include that change if/when I do an update.
I'm conscious that I don't want to hijack this thread so if you have any feedback/requests queries etc could you please make them over at the Denial forum? Thanks
