Hi guys and gals I've build my onw pc based mame arcade cabinet, using Ultimarcs iPac etc. etc. Everything is working fine, monitor, buttons, coins slots galore... but the coins stots can only use 1 type of coin, as expected. I was thinking of using the machine as an additional "piggy bank" where I can eposit any type of coin without having to change the identifyer coin inside, or using a button or the keyboard. I'm surrently using 5c coins, which is the cheapest currency we have available in South Africa. The 5c coin however is not the lighest/smallest coin we have here (i.e. the 10c and 20c coins are much smaller and lighter, then we have the 50c, R1 and R2 and R5 coins which is bigger - more is better, R1 = 100c). I was wondering if anyone knows how to hack the coin mechs to use any type, weight and size coins? I'm using the small, simple coin mechs, with identifyer coin slot and a seperator to determine weather the coin falls through or is accepted. Any help would be greatly appreciated
