nice work mate il upload later and get a rom sent of to dave and get back to yo on pm as soon as possible 👍

All done I had to code a small routine in in the rom and then emulate the 8 bytes from the CHR chip that the code uses for lamp sequencing.i did not pull apart the full lamp matrix sequencing usage of these particular bits and bytes as that could take weeks or months to complete and i just don't have that amount of spare time to reverse engineer the whole rom. Think this hack more like googling the answers during an exam rather than learning them but it does the job and seems to work fine if all the bits are cleared out of the CHR file in MAME. This now needs testing on an actual machine. Blue moon Test 1 file attached with $4001 bits 2&3 already set to disable the CHR and checksum tests. Feedback please on testing blu23_CHR_Free.bin

Just found this!! looks like the glasses have been drawn! love it! I want to re-create this machine!!

Only 8 bytes of info for the lamp matrix! Now if I could find the code sent that flips the chip between the chr side and the lamp code we could be able to reproduce the chips very good work by the way!!

Thank you for spending the time to sort this out I will do a video of the results as soon as I get the rom to test , unless someone else has a blue moon and the kit to burn a rom first 😁

Probably just as well. You can't expect to get fairly rare stuff like this for nowt.

The bezel is taking some time! I ended up going to Halfords and bought some BMW metalic paint, maybe not perfect match but it will need to do! Some imperfections after the laquer but I'm going to machine polish it once the laquer has hardened. Thanks to Mike for the rubber for the foot rest and Nick for the speaker housing. On the speaker the one I had was correct at 35 ohms but did not fit the enclosure! So i found one that fitted inside in a tesco dab radio, it is 8 ohm but I added in a 22 ohm resistor making it 30 ohms, this may reduce the volume time will tell. The speaker fitted but I could not get the back on the case so I cut a piece of white plastic the same shape to form a new back, So that's now fitted.
