I genuinely hope that GOG will someday release a complete After Dark collection as their first not-exactly-a-game product. I'd buy the hell out of it. Boris the cat has been absent from my screen for too long.

If all you want is Boris, Japan has you covered: http://en.infinisys.co.jp/product/flyingtoasters/index.shtml
It's not the original code and it feels a bit off compared to the originals, though :(

After Dark is the only reason I have a couple retro macs around the house, I like to fire up Lunatic Fringe, You bet your head, totally twisted and the simpsons savers from time to time.

The beauty of duke and the build3d engine was that they included the level editor with retail copies of the game, it was very capable and rendered the level in 3d while you were editing it and did it all on a regular pc.

In comparison, DoomEd was written for NextStep and required a really expensive workstation to run. It didn't take long for the .wad format to get reverse engineered and third party tools to appear, but build.exe was easy enough that any 10 year old could figure it out and try to build a copy of the school, house, bedroom or whatever.

It was fun to make deathmatch maps with overlapping sectors that created impossible spaces, that confused the hell out of my friends.

Is there video of this

Someone already posted videos of the engine and editor, but if you meant the impossible, overlapping spaces the best demonstration I've found is this video
https://www.youtube.com/watch?v=HQYsFshbkYw&t=1060s

I think the concept is called non-euclidean space, where several rooms can occupy the same 3d coordinates in space but which room you see depends on which adjacent rooms you enter them from. It was easy to do in 2.5D games where the engine only deals with a list of sectors. You can see how the staircase would clip into the rooms above and below but it just disappears when the camera is looking at a different sector that overlaps. It's a neat effect.

It's worth watching the entire video all the way through, it explains how those old engines worked pretty well!

The trick to make EQ not suck is to always use negative bias, especially with digital eq where the signal will clip really harshly if you max the volume, and only do subtle changes.

I use a big fat lowpass filter for casual listening because it makes my tiny computer speakers sound much bigger than they are, the tradeoff is that my max volume is much lower than it could have been but that's ok.
It's one of the perks of having an ancient firewire studio sound interface I guess

Remember the swap trick?

Most of those old consoles including the Saturn only checked the CD copy protection once at boot, and since were top loaders you could tape or glue down the lid sensor button, open the lid without the console knowing after it had checked the copy protection and replace the original CD with your burned copy. You had to time it just right so the console was finished checking but hadn't had time to reposition the laser and read the game executable yet :ninja:

Vibration and odd shapes are unlikely to be a problem for audio CDs that spin at the normal 1x speed, they only spin the disc at around 200 to 500 rpm.


The fun starts when you stick it in a high speed 52x computer drive that is full of warnings about not loading cracked or misshapen discs because of the risk of explosion.
The speed never increased above 52x because if you go much higher the plastic immediately disintegrates even with a perfectly round undamaged disc due to air resistance and resonance vibration

We also had a few Macs when I was in elementary school, we couldn't access the actual system but some sort of shell called "Finder", which had a list of approved programs you were allowed to use, needless to say none of them much fun (although we were able to entertain ourselves with the speech to voice features in some word processing software). If you wanted to get into the real Mac, you had to exit Finder, which required a password. Somehow we figured out that if you just kept hitting keys you would eventually just exit Finder anyway, kind of interesting how we were able to find a bug like that. It wasn't really that interesting, other than being able to play the picture puzzle games, but one day we put Finder in the trashcan to see what would happen. The computer never worked again and somehow no one ever figured out it was our fault.

Finder is the regular file browser on Macs, it sounds like you're talking about At Ease, a bundled add-on interface that restricted what users could do with the system

My understanding is that the slam tilt mechanism is just a springy piece of metal that completes an electrical circuit like a switch. If the coin box is slammed, that metal strip flexes and opens the electrical circuit, causing a slam tilt (game ends, complete system reset including loss of all credits).

I've heard that on some machines when a slam tilt occurs the cabinet will not reset automatically and the operator has to unlock the coin box and flip a switch to get the machine back online.

I've also seen some machines that look like they have a more sophisticated tilt system - it'll warn the user at first if it detects tilting before the tilt trips. (I saw a machine that played a "Careful! Careful!" warning voice.)

Yup, the slam tilt is supposed to be quite hard to trigger, it's there as penalty for idiots who really abuse the machine by picking up the front and slamming it on the floor. I'm glad it exists, because on my home pinball I rewired it so that I can trigger it by pushing the coin return button on one of my coin mechs to quickly reset the machine if I don't want to keep playing :v:

The number of regular tilt warnings is configurable by the operator, modern pinballs from the 80s and forward has a lot of configurable options like how long the ball save should be active, the score requirements for extra balls, max number of extra balls etc.

Tilt warnings are cool because it makes the risk vs reward an extra exciting challenge when playing tournaments. You *might* save your ball by nudging the machine hard but you could also lose your ball AND the entire bonus for that ball, which is a disaster during tournament play.

Refresh rate on arcade monitors are only 15hz, also they are much lower resolution than even an SD CRT. When I tried arcade games on a standard CRT TV (like one you had in the 90s) everything had a slight fuzziness too it and it just looked wrong. Also if you go the MAME cabinet route you need a special video card so you can run Windows at 15hz and 320x240.

you mean 15khz horizontal, the vertical refresh rate is generally anywhere between 50 and 60hz depending on the games resolution

You no longer need a special card, this genius programmer has made "CRT emudriver" which is a custom ATI driver for old Radeon cards, "GroovyMAME" a custom version of MAME that syncs perfectly to arcade resolutions and also if you're willing to risk breaking your GPU there's a custom firmware hack that lets you boot the computer directly in interlaced 640x480 so that the 15khz monitor can display it.

http://forum.arcadecontrols.com/index.php/topic,151459.0.html

I've hosed around with it for months trying to get it perfect, and eventually got to the point where I can no longer tell the difference between my original arcade boards and the same game running in GroovyMAME.

Also most old arcade games run 256x240 instead of the 320x240 we're used to from the DOS VGA days. I was surprised to learn both the NES and SNES use the same resolution!

Should I use groovymame even if I am already using the special ArcadeVGA card?

And quick question because you seem way more knowledgeable than me, but why do games higher res than 320x240 like Mortal Kombat 3 display properly on my standard arcade monitor? All this stuff is confusing.

I'm probably not great at explaining, but the 15khz monitor doesn't limit your horizontal resolution since that's just depending on how many pixels you send during a single horizontal sweep of the beam, the limiting factor is how many times you can sweep the beam from left to right without blowing up the circuitry that generates the control signals for the magnets that direct the beam

15 000 sweeps per second / 60 frames per second = 250 lines. You need some blanking time in between so the usable lines are probably a little lower.

The graphics card can display 640x480 by interlacing like they do in broadcast television, where the horizontal resolution is 640 and the vertical resolution is still 240, but the graphics card sends even and odd lines for every other refresh cycle so it adds up to 480 over two frames. (I'm unsure if it is also able to nudge the beam slightly up and down for the half-frames, I don't think arcade monitors do this but maybe some TV displays do since they are designed for interlacing)

As far as I know the ArcadeVGA card simply scales higher resolutions down to fit into the vertical line limit, so 1024x768 becomes a scaled 640x480 interlaced signal and text is almost completely unreadable. Arcade monitors also have a really coarse shadow mask / aperture grille which further limits how useful a higher resolution can be. I love how chunky it is, you can clearly see the red/green/blue phosphor stripes on mine :)


To answer your question, yes you should absolutely try GroovyMAME. Especially if your arcade PC runs windows 7, I think the guy who sells the ArcadeVGA still recommends XP because old mame versions used directdraw which works well with his cards but that stuff is about to become unsupported by plain MAME anyway. I have an ArcadeVGA too and non-interlaced games work great on it with GroovyMAME. Interlaced and vertical games are pretty hit-and-miss though. You should consider ebaying a card that is compatible with the CRT emudriver, they are dirt cheap.

Yeah, another cool thing is that you can get square 1920x1920 displays now that are great replacements for 4:3 monitors since you can play both horizontal and vertical games without needing to rotate the screen.

My dream monitor would be a 4096x4096 oled capable of black frame insertion for low persistence. Combined with a fake CRT effect done by a modern graphics card I don't think you'd be able to spot the difference then (apart from the display surface itself being flat instead of curved, but you can hide that pretty well behind a glass plate)

Check out http://www.testufo.com/#test=blackframes for an explanation of what makes LCD so different from CRT, the basic idea is that LCD monitors keeps displaying the picture constantly while a CRT scans the image from top to bottom with large areas of the display actually being dark (it happens so fast your eye doesn't notice) and that doesn't cause as much motion blur when your eyeball is tracking a moving object. If your LCD is fast enough to strobe the image without noticeable flicker you can get near CRT performance.

That's a neat scanline effect, it isn't that far off from the real thing

It's hard to make generated scanlines actually line up to the game resolution though, if it isn't some clearly defined common format like 640x480 or 320x240
Here's my CRT, it's hard to get a good picture since the camera goes out of sync. The dimming isn't visible to human eyes.

This was such an unobtainable dream computer when I first read about it in a 1993 issue of MacFormat. It only took 25 years but now you're mine!

All the sites that had copies of the weird DSP software seems to have disappeared from the net, I would really like at least the "sAVe the disk" utility from https://lowendmac.com/sable/06/0405.html

quote:

This system extension takes the place of several (now lost?) Apple patches and also fixes some bugs Apple never touched at all. Most notable is a bug-fix that speeds up programs that play lots of sounds, such as games. Every time a new sound channel is allocated, the "DSP Preferences" file is updated; what this means is that every time you fire a shot in Marathon, your hard disk is accessed - that's crazy! sAVe the Disk fixes this problem and more!

Yamahas XG standard could have been amazing if it had gained some more traction before games switched to prerecorded music.
It's a bit weird that MIDI hasn't changed for some odd 40 years

Also something magical happens when I play canyon.mid after playing a fancy XG midi file, it keeps all the insert effects. The main reason why MIDI sounded lovely in the olden days is that the playback was completely "dry" with no effects to speak of. Maybe a little reverb and chorus if you had a fancy sound card, but the Yamaha and Roland modules can do a ton more effects like distortion, delay loops, filter sweeps and so on. It makes a massive difference!

It's kinda rad that ATX has stuck with us for nearly three decades even if the slot design sucks for cooling.
I think it would make sense for an updated standard to make it mandatory for the case to provide fan cooling for pci cards and a hardware sensor standard where each card could report temperatures and control the system fans at firmware level so you could do away with the giant separate gpu fan shrouds that end up blocking a bunch of slots or suffocating if you cram too many high power cards in there.

Rack servers are much better at cooling in that sense, it's just one big wind tunnel from front to back and server expansion cards typically don't have any fans of their own.
