Not Telling
Hello
Thanks for reading this post, I've spent many hours trying to solve the following issue, even purchased membership here for the MPU5 Manual, however, Im now really stuck and need help.
The machine is currently set as the following:
Barcrest: Smash Martians (MPU5)
£0.30 Pence Per Play
£25.00 Jackpot
1 Dipswitch Prize/Stake Key
1 Fixed Percentage Key at 70%
Im wanting to change the machine to the following settings:
£0.5 Pence Per Play
£5.00 Jackpot
However, I've followed tons of configurations regarding the Dipswitch Prize/Stake Key however I always get "Invalid Key", I've seen on a few posts here a few members talking about the ROMS, possibly hard coded into the ROMS? If so how is this changed? This is a machine I've purchased for my soon to be games room.
Thanks in Advance, I've attached photos of the machine.
