Great in theory, but changing the hit freq of a machine means that someone has to change the eproms .....and that means that someone has to be a programer.......and that means that IGT would have to be involved.......and then gaming would have to test the software.........and that would never happen. so, the only other way that it could be done is to leave the content of silver in the 10s and the 200 the exact same way it is, label the 10's as 20's and label the 200's as 400's.........change the denomination of the machine to .50c the only thing you need is a gaming aproval on the strikes value.....pretty effortless least amount of change....IMO best way overall....but what do I know with my run on sentences :)
