Racing Jam/Thrill Drive Timekeeper Question
01/21/11 07:17 PM


So I have one working Racing Jam and several non-working boards due to the dreaded timekeeper failure and my question is this; are operator settings saved in the SRAM of the timekeepers or is it just protetional data stored there? It'd be great to just replace them with a normal 27C64 containing the data pulled from the working board but the settings for twin and difficulty would need to be changed periodically.

If settings are stored there and I did use an eprom, would the settings change until the cabinet was powered off or would the game simply refuse to function since it can't write the data to the SRAM?

Any help on this would be very much appreciated since I need these working asap.

Obviously the data would be available to MAMEdev since this is the european version and differs to the current asian dump in MAME (shifter type and probably other things).
