Greetings and welcome to an LGR thing! And this thing right here is the OPL2LPT

転換語

I bought one of these recently because it does something i have always

dreamed about. And yes I do dream of these things, and that is: it provides a

proper sound card that is not only using the parallel port, but is Adlib

compatible at an affordable price. Especially compared to a full-sized

original Adlib card. But yeah this really takes it a step beyond by going with the

parallel port. Augh, what I would have done for one of these back in the day. On a retro

MS-DOS machine with only a PC speaker having Adlib support is a notable

upgrade. But yeah the OPL2LPT is built and sold by Serdashop in Belgium, the

same folks responsible for the excellent DreamBlaster daughter boards and the

CVX4 Covox Speech Thing clone, among other things. And it is currently available for

30 euros for a kit you assemble yourself or 50 euros for an assembled and tested

unit, for a limited time. I bought the preassembled one because I'm lazy and I

wanted a plug-and-play solution much like the Covox Speech Thing.

In fact you might be thinking that the OPL2LPT is similar to the Covox and the

Disney Sound Source which I have covered here in the past. And that's true, but

instead of only working with software that specifically supports it, this

provides the much more common Adlib compatible standard used in thousands of

DOS games. And this is not just emulating it or imitating it in any way. This is the

legit way of doing it. It features an original Yamaha YM3812 OPL2 sound chip,

ahh! The same as the Adlib and the original Sound Blasters back in the day

and this is quite important to me considering I'm personally quite picky

about how I like my FM synths to sound. And while I would have preferred the later

OPL3 I'm happy with the 2 in this case. And there's a chance of an updated

version with an OPL3 in the future. As for the rest of the board you get the

expected male parallel port connector as well as a mini USB cable spot for power

and a 3.5 millimeter audio jack for sound output. And there's a

little volume knob on the end just like you'd get on an original Adlib card

from 1987. There's also a tiny reset button nestled

in there in case things go weird, as well as a jumper that can be shorted to

increase the bass output on the OPL2. Setting it up is straightforward as you

might expect: you just plug it in to a free 25-pin parallel port, plug in the

audio cable to your speakers or whatever, then power it via USB... which is one of

the more irksome pieces of the device. The PCs that I want to use this on do not

have a free USB port, so I had to plug mine into an adapter and into the wall.

And apparently you can also use a USB to PS/2 adapter and plug it into the PS/2 port

but that again doesn't work if you have that port filled up. Still even with the

extra cables dangling all over the place this is absolutely ideal for say, laptops

that lack a built-in sound chip of any kind. Or even those of us who want a

proper OPL2 chip on a desktop with something inferior installed already, or

you just have limited slots and you don't want to fill it up with something

else. I just have a bunch of tiny desktops and laptops and stuff that this

is ideal for, it's great. Now seeing that this isn't exactly working in the same

way as an original Adlib would, I mean, that didn't require any drivers or

really set up of any kind... This does need a little bit more to get

it going with your games. One program provided to do this is called ADLIPT

a TSR that lets your computer know there's an Adlib device present on the

printer port, just like there's an Adlib installed. But this runs into problems

with protected mode games and it also requires a 386 CPU or better, so running

it on an IBM PC, XT, or AT is pretty much out of the question.

And even running on a 100MHz 486 DX4 here I ran into some audio slowdown

and gameplay stuttering, so it's not ideal

So, short of running it on a much faster machine, in that case you'd want to use

ADPATCH which patches games directly to specifically look for the OPL2LPT

and also runs smoother while supporting sub-386 CPUs. The downside is that it

only supports a handful of games right now, and sadly this means that games like

Duke Nukem 3D don't yet work with the OPL2LPT at all. But for the games that

do work with it, dude, this thing does its job wonderfully. Despite the

slowdowns here and there on certain hardware, the OPL2 sound is dead-on as

it should be, and the fact that it's working over freakin' parallel just

amuses me endlessly. So with all that being said here is the reward, the payoff.

Yeah that's pretty much it for what I want to show of the OPL2LPT

I hope that gives you a good idea of what it can and cannot do. Such as with

Doom there you might have noticed that the sound effects were not playing.

That's because Doom uses digital PCM sound effects and the Adlib does not

generate those, it's only an FM synth. Now some games will modulate this and play

PCM through Adlib but most often that is not the case. So unless the game does

Adlib sound you are pretty much just gonna get music through this. And that's

just normal for an OPL2 Adlib compatible. Again the real downsides here

are if you're running it on a slower system then the games are probably gonna

slow down here and there and have some stuttering issues. But even on a faster

system with a Pentium or Pentium II or beyond, there's still plenty of times

especially with games after 1992 or 93 or so, where it just will not work. A lot

of my favorites don't give sound at all. Games like Duke Nukem 3D, SimCity 2000,

even games like Wacky Wheels it just doesn't see that there's an FM synth

there whatsoever. But really if the alternative is having no FM synth at all

on the particular computer that I might want to use this on, then well here you

go! For those ideal situations this is pretty ideal! And support for other games

will pretty much only improve over time as the TSR improves and ADPATCH gets

The OPL2LPT gets the LGR seal of approval!

EDIT: Um. There was supposed to be an outro here, but instead it's just quiet music.
