burn in is not a serious issue for galaga. It burns high score and number of ships at top and bottom of the screen. You can eventually get other burn (Especially if you leave credits on it) but generally black background so any burn is almost not visible.

I have fixed galagas for operators who run them 24/7 and with the tint screen in place, its not significant. But I did change out the monitors like 10 years ago to the last 19" vision pros. Pacman series and centipede are a different story. It will start to burn a monitor in under a year. Really bad in 5 under heavy use. games like dig dug and donkey kong will burn their screens, but generally at a much slower pace. .

in general, once the monitor has been rebuilt, its probably going to be fine in home use for a decade or so. If it has a wells or a g07 in there, there probably will be parts for them for the next 20+ years. If people are keeping pins from the 50's running, your going to be able to keep vids running.

if you dont have the skills to rebuild a monitor, there are people out there doing it. If you watch a youtube video, you can easily pull the chassis and mail it off. If your adventurous, a you tube video can show you how to rebuild a monitor and do a tube swap. yes, there is high voltage involved. but learn a little and work safe and its not that hard. I had 4 years of high school electronics(we built oscilloscopes our senior year). When I started collecting, I would watch people repair and ask questions. eventually, I learned enough to do most of my repairs. When I got good enough, I started buying broken games, fixing, and selling them.

one thing to think about is if you have an old 19" tv from the early 80's to the mid 90's, dont throw it away!! It probably has a tube in it you can use for a tube swap. Tube swapping is pretty easy. Just a matter if you have the right tube and a compatible yoke.

as for joysticks, you can buy vintage joysticks and rebuild them. Wico made most of the old leafs. You can even steal all the parts you need from old wico sticks they sold for the home market(2600- home computer). the main failure is the leaf switch and the centering grommet, they sell repos of those. Also repo joystick shafts and people even repo the joystick housings(big problem with the atari gauntlet style joysticks).

there are probably 100 joysticks out there. you can find a decent one with a little effort. If you like a loose stick, find one that features that. There are even optical sticks you can use. Or go vintage sticks. really no excuse to play with crappy buttons and sticks. Many people are even upgrading the arcade 1ups.

Cocktails are nice for casual people to sit at, eat and play a game or two I've found. So the benefit is while it does take up space it can still be utilized as a table (if you don't care about people playing Jenga on it or eating pretzels and a beer on it). I don't like the space it takes up per se, but it's a fair trade off. I think a stand up arcade has more draw as u walk up to it, vs sitting down. Get both. I have Frogger, but will probably do a 60 in 1 with it only because it doesn't have the long term draw with it. Repetitive levels and short attention spans only keep people playing for about 2 games. I don't have much experience with guests and mame/60 in 1's, but I do know when I have been with people they need to get walked through on how to select and start a game. I really want to be hands off when people come over rather than the arcade repair guy and how to person. Would much rather just be a part of a mix with people who can entertain with what is available and it all works seamlessly!

If your going to do a frogger conversion, go this route so you don’t mess up an original. Adapter, switcher, and pcb and you should be able to covert it for around $150.

Put a post it on how to start the game. I have seen 7 year olds figure it out. You can also remove 59 of the games. Then it will only play 1 game. Or limit it to 6 so it has only 1 select screen.

This is the other reason I hate 60-in-1s, they butcher dedicated cabinet that could otherwise be restored to original condition.

I was just suggesting to the guy who responded thinking about killing a classic, to do it in a way thats reversible. not everyone can have 100 games. So going multi and not killing a classic is a good way to do it.

there are people all over the place butchering classics. All you have to do is check craigslist people trying to cash in. Maybe if you educate people on how to do it without destroying a game, you might put those craigslist hacks out of business. you cant just put your head in the sand and pretend its not happening. If you help people do it in a non destructive way, your actually saving a game. I have done maybe a dozen 60 in 1's for people wanting more out of their pacmans, dig dugs, donkey kongs, ect in a non destructive way. Sometimes people ask for say a pacman cab with a 60 in 1. Many times I can push them to a dynamo hs1 or an already converted cab. Dress it up with custom art and they are usually happy with that.
