Yeah, I'm talking about the SINGE files as that's all anybody has been able to find.

Wow, the quality is much improved in this version

Did some comparisons running the old video vs. jwallace's new one in WinUAE.

Besides the much improved video quality; when watching the intro on the old video, it fails shortly after Gallagher says "Why it's a shooting game..." and resets the system.

With jwallace's new one you can view the full intro

Yes, the old one is missing approximately 2 minutes of attract mode, all the credits and (and this is something the user wouldn't have known) a few minutes of blank screen. There's two segments with this blank space in the disc, and I'd think it was representing footage that had been cut, or other language.

As I say, if anyone has the DEXTER data for ALG games, this method is pretty robust now.

Although I would appreciate it if someone mirrored those videos on a more legitimate host, I don't seem to have Zone upload access.

There was a guy who posted in this thread that had some Dexter videos, but was unwilling to share: Westonboy88

Regarding the "XVID" version you did; as LanceT mentioned it's not available on the hosting site.

See here for access to The Zone!: http://eab.abime.net/showthread.php?t=26201

It's only a temporary storage area though (60 days) and you are limited to 80MB files...

What you really need is an Amiga File Server account, but 50 posts are required for that.

I downloaded your file so can upload to the above though

Edit: Ok, have now uploaded all working ALG games to here: /Misc/American Laser Games

Guys, what ever happened with these?

Here is something I will leisurely be working on in my spare time. The crackle in the audio is due to me running in virtual box (win7) while running win 10 apps.

Not sure if I should use the original video or the singe version.
Had to 1st convert the ogg sound files to mp3 in order to load them in after effects which accepted m2v video files.

Thanks for the upload, I'm surprised the XVID version isn't up, but the MJPEG version is closer to the original in terms of quality, and of course, has more key frames so the seeking is better.

It should be the same base link for XVID, but the end is
'file/vsynqdic73xiqbn/ggXVID.avi/file'

The only advantage it has is it's a more commonly used codec, and it's a bit smaller, but I'm a quality snob so I wouldn't necessarily recommend it.

I have no desire to post for posting's sake, but if anyone can direct me towards actual laserdisc or .ldimg files for these I'll happily do the conversions. Not sure if I've already said this, but I'm pretty sure a user on here said they had them, but couldn't do anything with them (I want to say it was westonboy88, but I'm not sure of that name). I've tried reaching out, but so far no joy.

If anyone else is on the hunt or can help me, I believe the .ldimg was originally put together for a product called Dexter, which supported all known laserdisc games as a solid state player replacement, so there should in theory be a video for everything it purported to run.

Gallagher's Gallery is the freak of them all though, as I think the people with the home rights released everything else, with possibly the exception of Fast Draw Showdown, and that will look wrong in emulation as the game is designed to run on a rotated monitor in portrait configuration, which I don't think is an available setting. It also uses a holster switch, but I think that's the same as the reload one we already have, just mounted differently.

Has anyone checked Platoon (one of the games we have full video for)? In theory, it's the ALG hardware with a different ROM scramble, but it looks a bit different when you merge the ROMs together, for one thing, the image doesn't seem to start with anything meaningful until $1000 (header notwithstanding), and the diagnostics seem utterly unscrambled.

I've attached a merged ROM for those people with more expertise to take a look, I don't know enough about the Amiga side to see if this is mapping correctly or not.

This is literally the one from Dragon's Lair Project merged into one file.

Afaik no one has reversed the ROM encryption yet.

I see now, although it looks like it has a correct header right at the start of the ROM, there's a lot of padding straight after it instead of the 'correct' program.

I should have realised it wouldn't be that simple, but I'm prepared to see if I can find it. Of course, the assumption that it shuffles at the 0x7ff byte mark isn't guaranteed here, but I don't see why they'd reinvent the wheel when effectively they're piggybacking an existing hardware setup anyway (the dumping notes seem to suggest this was on an ALG RAM/ROM board).

OK, so Platoon appears to have a standard header at the start of the ROM, and then at around $1000 in the file ($f01000 in mapped space) there's a softlock as it branches to itself (60.00.ff.fe)

Everything else looks like normal code, albeit in a number of languages which I presume is configured in the real thing. I know people were checking with wrip before - I can't on this but I'm wondering why there's something trying to execute there - there's only the one header at the top, after all
