Midway Hyperdrive (saving/coin-up/cosmetic)

[ironblock]

so i have been working on my hyperdrive had to re-wire the steering wheel and the view buttons.
and all controls work now.
i also found the manual that fits the motherboard : http://www.gamesdbase.com/Media/SYSTEM/Arcade//Manual/formated/NFL_Blitz_-_1997_-_Midway_Games.pdf
its not the same game but it is the same pcb  only a 50 mhz slower cpu.

saving

the game does save the settings but not for a long time.
i thought it would save the data on the hdd.
i have not been able to check the button cell on the pcb (i will soon)
but i think that is for the internal clock.

coin-up

living in an European country i would like it to accept 50 euro cents. and it only takes 2 euro coins
if it were a mechenical coinmech i would just replace it.
but it has a c220b coinmech. i have read that you can change it with the dip switches near the eprom
but i have not found any dip switches.

cosmetic

the left control pannel is a bit busted. and some side art is a bit scratched up.

this is how it is supposed to look.

and this it what my left panel looks like. (go pro makes blurry photos sorry)

if you have any suggestions how to fix this tell me. i have access to a 3d scanner but not a printer. (can send the files to a company tho)
and i don't have the 3d skills to fix it in 3d

side art photos coming soon

will add more along the way.
