What's that sound? It's 4 Amusement Only, the EM and Bingo Pinball Podcast. Welcome back to 4 Amusement Only, this is Nicholas Baldridge. Since last episode, I finished up multi-races, at least as far as it's going to be finished before the York show. I've got all the buttons installed and everything functions as intended. All 10 games are now Now playable and selectable via the menu system. The menu system turned out to be a much bigger challenge than I anticipated. Everything worked great in a simulation mode, but once hooked up to the actual hardware, it no longer functioned. And the way my menu works, I have essentially two threads, one main thread, which contains the menu system, and then a secondary thread is spawned and joined to that main thread in order to allow and some other things that you can use to play the game that you've selected. Franchihales, and then that thread is destroyed and you're back at the menu if you choose to stop playing the game for whatever reason. Franchihales, So when I hooked it up to the actual hardware, it was claiming that the USB device, the P3 Rock, was still in use. Franchihales, and I tried everything under the sun. I mean, I really tried everything. My jouney so all sticker one know we put above the issue is always the same. So like ended up doing was look into a source code for with pinznwart bioucs is the undere I'm a fan of the P3 Rock hardware and handles the setup and teardown of the connection between the USB device and the P3 Rock, the hardware. So, looking in there, I found a function called prdelete and I thought I was going to have to call that manually and just write a little C program to quickly set up and teardown that connection as needed. But it turned out that I was able to call that and the Pinball the Pinball pipe in proc function and this is the Python library that allows for communication between Bob Libbe pin proc and the actual hardware But within pipe in proc there was a similar delete command that actually just called peer delete under the surface so whereas before I was trying to use Pie proc game to set up and close a connection like I do on the multi bingo It turned out that I needed to make this extra call to extra super kill the communication between the USB device before I tried to enjoin that extra thread I was talking about So I have no idea why this doesn't work on Multiraces, but it worked on the Multibingo. This is very similar code. It's not exactly the same, but the actual code that's handling setup and teardown is the same where it was. And I just couldn't explain it. So at one point, I messaged Gerry Stellenberg, head of Multimorphic, who makes the I was asked to explain the board set that I use in Multiraces and asked, in Multiraces I'm using a version 2 of the board and in the Multibingo I was using a version 1 and about the only thing I could even suspect was that maybe version 2 had some kind of difference in the FTDI chip that it used that was causing this problem. But I swapped in the board from the multibingo after some quick advice from Jerry about pinouts and so forth, and the problem was the same. So it didn't follow the board, which means that there's some kind of underlying hardware slash software problem that's built into the computer itself. So I reached out to the custom pinball community and had quite a few suggestions and eventually just settled upon diving into the source for libpinproc to figure it out. But I do very much appreciate all those folks for trying to help me and taking the time to try to figure that out as well. jump, drag-t eines, 24 aspiration into kick cardio, The MultiBingo, which has 142 games ready to play. MultiRaces has 10, which is one-sixth of the total library of one-ball horse race games. Aside from those games, Universal's 5 Star will be there and I'm looking forward to seeing people play that game because it's quite difficult to do well on it, but it's very fun and very challenging. Mr Knapp and the video My name is Michael Parczynski I am president of cleanup is the part I serve and I am the seiner of the specialize goat And I very much looking forward to seeing everybody there and teaching people how to play some games and maybe even fixing one or two if a problem arises But I will also be there as part of Coin Op Carnival. This is one of the last three stops in the Coin Op Carnival 2019 release tour. And for the first time in my years of attending the York show, I will also be a vendor. So I'm looking forward to that. It'll be a different experience. Bingo Row I'm hoping to put right in front of the booth so that I don't have to jog very far in order to sell somebody a book if they would like to buy one. But please come see me there and come see Bingo Row. I will have some surprises, some giveaways as usual, as well as the full complement of CoinOpCarnival merchandise available for purchase. includes t-shirts, pins and books. So I have quite a bit more to do before York, so let's finish up with today's featured game which is Headliner from 1939 by Bally. Headliner at first glance reminds me very much of nightclub or frolics, nightclub being one of my favorite games of all time. Headliner has and a variety of women in the background who are standing on various stair stepper pedestals all the way up to the top and before them there are five different dancing women each holding a balloon and they are arranged in sort of a chevron pattern and below them is actually the orchestra pit with the band. It's pretty cool to see. But one of the big draws of this backglass aside from all the mirroring which is gorgeous are the curtains. It's been a while since I've talked about a game with curtains and this game has them and it's pretty cool looking. I really dig the artwork on the backglass. Um, looking at the playfield, as far as artwork goes, I really enjoy this too. Uh, there's a chevron of bumpers, one through five, each of which has one of the women with the balloon on top of it. And if you hit that bumper, I assume their balloon lights up. And of course that's the main sequence in the game. If you hit all five, I'm sure something good happens, be it to light the various rollover lanes or, uh, to award you replays. I not sure which There no score and Instruction card available online that I seen So I just looking at pictures and making some conjecture here But the chevron bumper pattern has done well in numerous games throughout the years and I always find it very challenging especially with the post placement that I looking at here with posts arrayed just above the spring bumpers making it very difficult to hit those as you coming down You can just kind of waterfall down one side or the other and hit all the bumpers You got to go in the Gaz,'Lasan esduro, did some history in Ar invert expenses Ee impexo do not want to que surgery on you procadsSo it can't be a cover card Igor CousGH. Summer, of part 2? Lefaksov, Ken perto na Lis strength, cava menstruale. Adadajajajaj, Belov Royal Mrollexia,yun, I'm gozoano, J administro, I'm not lit, I'm not sure, but I do know when it is lit, it's a thousand points. There are also rollovers to the left and right of the head of the arrow, which score what appears to be a hundred thousand points. So those are the most lucrative rollover on the playfield. Near the center, there are two V's, both green, comprised of three different spring bumpers and a rollover. The The pinball over when lit scores a thousand points and again I have no idea what it scores when unlit but the overall effect of red, yellow and green is very gratifying, it looks really awesome I think and the artwork on the playfield there are two dancing women down at the bottom and they're dancing over a musical staff with eighth notes hanging out on top. I'm a fan of the game, and it's one that I've never seen before, but it's one that I'm very interested in playing one day. Hopefully I come across it in my travels, because it looks like a lot of fun, and the artwork is deco, gorgeous, just wonderful. So, that's 1939 Bally Headliner. Well, thanks very much for listening.
