I think that only the freedom of the source code would be an issue. The assets (textures, sounds and whatnots), as long as they're not executable, might be exempt of that requirement, while the product still RYF, because you could always make your own. Anyway, that's my take on it. (And of those reimplementing various game engines -- openmw etc..)

The scanners are another can of worm.
Most USB-to-IEEE-1284 adapters work at a high level. They usually present themselves to the computer as a "USB Printer" class. They do not let you directly control each pin individually like on an actual parallel port on a computer.
At best some specific USB adapters could implement some of the more modern official "bidirectionnal" protocols officially featured by parallel ports (like ECP/EPP).
*IF* the USB adapter you're considering offers these bidirectional modes (instead of being plain classical SPP port masquarading as an USB printer on the computer side) *AND* the scanner you're considering explicitly supports the bidirectional modes (instead of require direct bit banging on the port, like some old I2C web cameras did), you might manage to get it to work with some well behaving drivers.
Otherwise, you're better off trying to plug the scanner into an Arduino or some other intermediate step with GPIO pins.
That's the reason why scanner moved as fast as possible away from parallel port and into either SCSI for high range professional scanners or USB for home office devices.
Originally posted by dos1 View PostCan this parallel port cable actually address individual pins or does it just show up in the system as USB printer? If it's the former, then it's actually way more useful than how you paint it.
The USB device you're looking for is an Arduino (or any other micro controller with tons of GPIO ports).
That will replicate all the functionality one used to have in classic parallel (and joystick) ports.
USB-to-parallel adapter work at a high level.
The present themselves as USB printers to the computer.
They can receive data packet from the computer that they'll automatically stream on the data-pins on their own.
They will monitor the parallel port signal pins and emit the corresponding alerts to the computer.
That's good enough if you want to send a .PS file to a laser printer and get an alert in case of paper jams or no paper.
That's absolutely no good for the devices that repurposed the parallel port's pin for other thing (using the 5 signals as 4 bits I/O+strobe to be continuously monitored on the motherboard's IO ports).
Early PC-to-PC copy cable fall into that category.
Some devices implemented arbitrary protocols over the pins. e.g.: I2C cameras, using the parallel port to connect console game pads, DAC such as the Covox, etc.
The only exception is a few *official* standards for exchanging data over parallel ports (where on motherboards it was even possible to have the chipset itself assist in data transfer by handling DMA and IRQ: ECP and EPP). One didn't just randomly bit-bang the pins for any arbitrary protocole, there was a set specific way to send data streams in both directions.
Several disk drives, tape drives and some scanners used those.
There are a couple of rare and expensive USB adapter that implements those.
On a windows box they'll show as LPTx: ports that handle the API for those officially bidirectional streams, a well written driver that correctly asks for those modes could work with such USB adapter and bidirectional devices.

As for the game assets, I don't see why that would be any different from the source code. Suppose, for example, I create a picture in an image editing program. My file would contain all of the layer data which allows for easy manipulation of the image. But for everyone else I just export a compressed, low resolution JPG file which has none of that. Same principle, right? It's digital content, and the end result is much more difficult to manipulate than the source. It seems to me that under this logic, when Disney releases a movie, all of the development assets for that movie must be made available as well.Last edited by Chugworth; 17 May 2019, 09:09 AM.

Here is the real "living outside reality": For most people, and especially the sane ones games are added bonuses, not the sole reason for being. Rockstar isn't a major company on anyone's radar, and GTA is not essential software.
Gamers are delusional. There is this mistaken belief that Free software or Linux communities are desperate for them. We are not. Remember, a game needs an OS to run on, an OS does not need a game.
I would argue that gaming is what propelled the use of windows, that and cost. Many wouldn't use it but for the fact that games are supported by developers on that platform. Chicken & egg? Perhaps, but it does explain Apple's poor gaming experience.
For example, Apple is a high cost platform meaning a smaller market share, PCs can be obtained far cheaper at comparable/better processing power. So why isn't linux the choice? Cheap platform, free OS, been around a long time and yet abysmal gaming experience.
Either way, the boat has departed now, though, as consoles are the future (and present) and that's where the money is... aha money; something linux users as a generalization don't like to part with.

Too bad later Atheros got swallowed by Qualcomm and these once again proven they are proprietary blob fans, so ath10k is pretty blobbed proprietary something. Still, if one does not wants to run plenty of unknown code in sensitive place (wireless network device), ath9k devices would be very decent choice. That's where FSF gets the point.
p.s. as for apple gaming experience... here on phoronix you can find benches where opensource mesa beats dust out of apple's graphic stack. I guess they just failed to create optimized graphic drivers for their graphic subsystem.
when Disney releases a movie, all of the development assets for that movie must be made available as well.

Open source is great, and certainly has its place. But when you want to make a living from your open source work, then things get complicated.
