Building a custom arcade setup

Chris John Hunter:


You mean you want to run multiple competitions but can't be watching every machine and want the winners to come to you with their ticket, wack them in the next round or give them their prize etc etc.


Unless you wrote your own game or had access to a game that allowed you a lot of control / output a file containing the info say a log file I am at a loss at to how you could achieve it


Good luck though :cheers:


Another thought, hack the rom but it isn't easy. You could try a Capcom System 1 game. I am having a go at this soon to backward port Lemmings . But you would need Machine Code 68000.

It would be far easier to hack a PC game with something like a Game Genie ? Do they do those for PC do you remember them? Well you freeze the game all pointers/numbers in specific locations/Memory mapping are analysed if you played about a bit you could probably get what you want but its no easy task.

Unless its worth a few bob id shelf the idea.
Chris John Hunter:
Or.

A pc fighter that uses online. It would need to store who won what when somewhere. And you could edit that or analyse that ini file .

I get what you're trying to do and I think it's a fun idea for a home system but if you're going to use it in the way tickets are used at real arcades I have the same concerns as RandyT.  You would have to work in meters to gauge what's coming back on the line to see if someone is pulling tickets and cut the power flow back.

If you're super serious I would either look into a PiFace or some Sensa relays where you have a bit more motor control.

Can you make a cookie dispenser for every time you exit mame? Every one is a winner?  :cheers:

I can set the number of degrees to rotate with the arduino, and therefore set the number of tickets dispensed. Each winner would receive a ticket that basically allows them to challenge someone to another round of the game. Out of tickets, out of the tourney.

Hopefully, this is a "trusted environment" :).  Ticket dispensers, while easy to make, aren't as easy to make robust enough to handle shenanigans.  Aside from the obvious possibility that one could grab a ticket and pull out as many as they want, there's also the possibility that doing so could turn your motor into a generator and feed enough power back to the controller to cause some damage.

This is also a bad situation for a servo, depending on the size.  The smaller ones have a tendency to come apart at the press fittings of the gears when forces are applied to the output spindle.

But, if it's a home setup, with folks who are well behaved, what you have will work fine.

It is indeed a trusted environment. However, I'd be amazed if anyone managed to pull tickets out without tearing them. I thought of this inevitability, and the drums I'm driving that roll out the tickets perforate the tickets length-wise. As far as the ticket count, the tickets are a standard length, so I just count the number of degrees I need to rotate the servo to dispense the ticket quantity I want. I think its something like 28* for one ticket on my setup, my notes aren't right here but it's something like that.

I guess I should have explained a little better. The spool of tickets just sits idle, and I draw the tickets between two rollers that are pressed together. I drive one of the rollers with the servo, and it *may* be a little oversized for the application. (Think small household dryer). The rollers themselves are gear mated, and have pins/sockets that interlock. As the tickets are drawn through, the pins punch holes all the way down the length of the ticket, so if anyone tries to pull too hard, the ticket tears and is invalid. The paper tickets will give up the ghost way before anyone can drive any power back through the system, besides, the gear drive is on a one way clutch, so to the would be ticket thief, best of luck getting some tickets.

If you can pull it off, I'll buy you a beer.  :cheers:

This whole thing is basically an excuse for me to make some neat robotic stuff. With video games.

I think you will ultimately find that the ticket thing is going to end up being an incredible amount of work and money for something you ultimately won't end up using more than a few times. I know a lot of people with a lot of games and some of them are indeed games that can dispense tickets, but I don't know of anyone actually dispensing tickets in a home environment.
