Quoted from barakandl:
update the ROM to a bug fixed version or get the RAM clear software from my website MPU info, bottom of the page. the "divide by ten" version is probably built around the bugged meteor software. Back in 2018 did not fully understand the bug yet and was still stuffing bugged meteor ROM on boards.
The bugged meteor version does not sanitize a section of RAM used for the sound board at start up. A few other games like Ali and Nine Ball have similar RAM issues, but eventually those two games are able to fix themselves (9 ball after end of a ball, Ali end of game). Background sound in 9 ball is weird until one ball is finished. The "bell" noise in Ali gets odd sounding.
Thanks, so glad for your help - I will definitely do that.....may get the bug fixed ROM - I assume the chips are socketed in and can be easily removed?.......
I don't see the ROM offered on your site, are you selling these?
Thanks again, Nate
