Wackyputt/Rigolfeur Help Needed

Hello,

I'm in charge of a wackyputt and I have a big problem.
The boards that make the games under the holes were programed by a win95 computer running a 16bit software. The computer just crashed and the software is unrecoverable (many tried).

The boards Are essentially based on a SC87C51CCN40 8bit microcontroller and a BQ4010MA-150 Memory chip. (with a few other minor other chips)

I need to be able to program the HEX files that I have on the memory chip
and if possible to recover and program the microcontroller. Both chips are removable from the board...

I will gladly provide an example of one of the Hex files if necessary and also pictures of the board an the chip numbers.

Are you asking what is a suitable programmer to buy? Do you have a spare ROM?

Well...

well if an arduino with some more parts can't do the trick then yes I am asking what programmer and software will let me write the Hex files on my BQ4010MA-150 Sram Chips

Thanks
