Right now that I've read through this again I've had a thought
As I understand it the ROMs on the left side are graphics ROMs and the 2 on the right are main CPU code with the small one being sounds I think?
So to start with you really need to be focusing your attention on the main CPU code since you're getting the music but no game so far. The PAL isn't the issue because if it was you would have a working game but in 1cm blocks all over your screen (I had this PAL fail on Hyper Fighting)
What speed are your 27C4096 and have you verified them?
set the three dips witches to the same as mine are. I had to swap two roms over because I was getting graphics corruption on title page.
Almost as if the zip on the French site had two of the files renamed in it to make it difficult to replicate unless you knew the crc of each rom.
I used -120 eproms
Just to confirm:
DIPA 7,8 on
DIPB 1,2 on
DIPC all off
