Popping up from out of nowhere...


I mentioned this in Discord but I might as well crosspost here:



This is Kim ‘Kanonarm’ Köbke, Gyruss Marathon World Record Champion, watching my Tourney record-break run from this past September’s SC3 that I set on my cocktail.

Does anyone care about these kinds of posts? If not last one I'll bother with

Anyways I had mentioned that there wasn't much I wanted to do to Jubeat. I lied.


I got to ripping the machine apart with a few goals in mind...
1: Replace the rubbers in the controller with new ones

Jubeat's controller are a 4x4 grid of squares where each square has 4 contact points. The corners on the buttons push a rubber membrane which makes the contact

Here you can see one of the pcbs removed while I was preparing to remove the rubbers, scrub the buttons and then put new rubbers in

Then the "fun" process of checking all 64 contacts individually to make sure that they fire properly and no misfiring is happening due to crap alignment. About 2/3rds of the membranes removed were brittle and on their last legs.

This brings about #2 of fixings....

Testing out the sizing on a freshly cut pane of plexiglass :heysexy: and it appears I in fact didn't gently caress up ordering it! The drat thing is the right size!

All cleaned and placed, a great improvement over the previous panel!

With the panel in place all that was left was putting everything back together while trying to keep any dust out. That's pretty much all I really wanted to do with Jubeat. Having new rubbers and this plexi basically makes the thing feel brand new. Total cost for all the parts was just over $100 which all things considered is impressive how much it improved the cab's gameplay.

Edit: if you were curious here's a glimpse into how scratched the old plexi was

God speed, hopefully it goes better than my "fine I give up" settling. Too cheap to pay for SFEX2+ and a EX2 popped up on ebay that I got for $25 shipped "untested"

well..



both the ZN A and B boards were warped beyond use. The chips however were legitimate US and I have a "bootleg" "Taiwan" Plasma Sword which is just the Japanese version with some counterfeit stickers on it. I was also able to move the game label sticker over from the custom asic and now I have a nice looking, working SFEX2.... non plus :( but $25 is a lot better than $200

A few years ago my sister in law's boyfriend asked me if I wanted an NBA jam cabinet, hell yeah I did.

Went to get it and it was a bastardized gambling machine with a "rim rockin' basketball" 8 bit pcb. With a hidden switch under it to switch back and forth.

I was disappointed, but took it anyway.

Just picked up this empty Astro shell. It's missing the power supply and monitor. Luckily, I have a spare power supply and monitor*



I can't wait to clean this thing up. Despite how it looks it's mostly just very dirty, and is otherwise in decent shape.

*the monitor has graffiti scratched into it, which I am in the process of polishing out.

Ask me about the weird experiences of buying arcade machines from KC in Southern California.

My phone took a poo poo so I didn't have it available during the entirety of the work on this, but last night DanAdamKOF and I cleaned the heck out of this thing, and then put it together. Now I just need to buff and polish the monitor to remove the graffiti. I started logging that process in the DIY section.



The closest thing to a bait & switch is that it seems he forgot to include the front PCB door. I'm sure I can get that resolved...

So here's something interesting. I've messed with a lot of game settings and never seen anything like this. Is there any truth to it?

TVTropes (yeah I know) posted:

As another general example, a lot of arcade video games have settings adjustable by the operator that controls how unwinnable a game is. If it's not disabled completely, once a player has played for long enough, the game will create an unwinnable situation at a certain point that cannot be overcome until the Game Over screen appears. If the player has another credit ready and chooses to continue, the unwinnable scenario will be replaced with a winnable one. The idea is to keep money coming into the machine frequently and regularly, no matter how skilled the player is, so these unwinnable scenarios are designed to look like the player is not good enough to survive them.

Many arcade games have settings to adjust number of lives, continues et. al., but I haven't seen any settings that outright rig things.

However, many arcade games do increase difficulty as you play with the aim of having the average player's credit last a little over two minutes, so as to lower the chances of one guy hogging the cabinet (as opposed to having multiple people plonk their coin in!) while keeping them playing long enough to not feel ripped off.

I was playing neo geo Magician Lord with a cheat code for invincibility recently, after not dieing for some time a creature appears that flies in to you and you can't kill it.

It hits you so much that you can't even progress while invincible. I presume the case is the same if you were really good at it too and not cheating. So yes, that game does that.

Popping up from out of nowhere...


A thing I’ve observed with Gyruss’ incremental difficulty:

The TG-ranked difficulty setting is 6. Default of the machine is 3. Max is 8.

Here’s the kicker: everything in Gyruss rolls. Lives, stages, score tables. They all roll over.

The difficulty ramp is no different.

In my last record break, there’s a moment where I call to my friend Jared and announce, after I am in Loop 4, that the game slowed down to a crawl. “The promised land!” I was able to survive on a single life from that point forward BECAUSE of that roll!

So, start at six, loop the game 3 times, go 6-7-8-roll, and you’re at 1. There’s no 9 in that table.

So, in a sense, the game can be charted for difficulty in a breaking wave.

I have no idea how much other people give a poo poo about Gyruss, but it fascinates me.

Awake and unreal, off to nowhere
I really wish I could remember the game, but I'm pretty sure there's an arcade game that will outright kill you if you survive for x amount of time. It wasn't something that an average player will ever see, but something I remember seeing with people on Twitch who try to 1 credit clear games. Although it wasn't a dip switch, was something literally built into the game and not something an operator had control over.

I forget if it was Revolution X or Terminator 2 the Arcade Game but one of them was discovered to be literally impossible to beat on one quarter. Like the game would just randomly kill you no matter how perfectly you played.

A golden helix streaked skyward from the Helvault. A thunderous explosion shattered the silver monolith and Avacyn emerged, free from her prison at last.

I want to say Revolution X has enough unavoidable damage that it's guaranteed to kill you before the end, but I'm not 100% that's the one, nor would I be surprised if this was true of multiple games.

I could swear I remembered reading this about one of these two, so I decided to check out the Revolution X operator's manual to see if they came clean about it in there. And, sort of?



The Terminator 2 op manual has a similar entry:



I suspect this "minimum guaranteed playtime" is another way of saying "how long before the player starts receiving a tsunami of unavoidable damage".

The "unwinnable" setting stuff is usually for bullshit games like Stacker, etc. Redemption titles, with a percentage payout, like a gambling machine. This is more or less not a thing in actual games, but a lot of very late '80s games have kill screens once you reach an absurd level. It's very, very rare to have a game that is literally unwinnable.

However, I haven't played Revolution X, or very many American-made light gun games in general, so maybe those are actual turds that you can't beat.

That Midway/Williams architecture dictates that you will not 1cc the game. You must pay out to see the finish. It’s also crowd control.
