The point I am making is not that it is unstable, but that it tries to fix something that isn't broken; the dynamic_x86 core uses the *_checked memory access functions which don't trigger inline page faults. If it didn't use them it would have issues when self-modifying code touched the currently …

You should just rip it out, it doesn't fix anything (which should have been verified before it was committed).

Then I played some ThemeHospital. I played that the first time the other night without VBE, but with it it runs even better, and I managed to basically grow to having 2 wards, 3 GPs, and a handful of Clinics in the span of about the first 30 minutes. The night before I played till I lost. I'd be …

All the stuff DOSBox-X added to the dynamic_x86 core to "handle page faults" is mostly nothing but a huge slowdown. Nearly all memory accesses performed by that core (dyn_read_byte/write_byte/read_word/write_word) already handle faults correctly and the remaining opcodes that can cause problems ( …

Reducing the number of files is counter intuitive. No it's not. Those old games certainly aren't going to need 40, 80, 120 files open concurrently - and the reason the "files=" setting exists in the first place is because the memory for it has to be static/reserved rather than allocated dynamically …

Descent doesn't really suffer from desync, clients just update other clients with changes to their status. There's no prediction or sanity checking. You can have a ship that is impervious to damage and moves five times faster than normal and other players won't be able to touch it.

As an example, then Nasa used Amiga for some calculations that were critical for the launch of the space shuttle. AFAIK they are still using RAD hardened PowerPC CPUs (the successor to the 68000s) in some modules due to their reliability during prolonged exposure. Or it may just be because they're …

With all due respect, in the context of USB-C, all your statements are wrong, except "Ports can implement different functions" .

it is the fact that identical looking USB-C cables (and ports, for that matter, but at least device specs can easily be looked up) can have different functionality (i.e. support or not various alternate modes and power profiles) without any external indication . No. A cable is just a bunch of wires …

What is USB-C for anyway? USB-C replaces everything USB related (full-size USB, micro USB, mini USB) plus a bit more. Most laptops nowdays come with no external ports except a couple of USB-C, which is used for charging and provides connections to other peripherals (HDMI/DisplayPort, ethernet, full …

No problems for single player but you probably wouldn't want to do that if you ever intended doing any PvP (although I doubt anyone is still using the original builds for that) - viewing the map screen makes your ship visibly stop bobbing for other players so it was considered an AFK/"don't shoot me …

Most of Descent is programmed to handle variable framerates so there was no need to limit the maximum framerate. But unfortunately a few things slipped through and still update per frame instead of per ms, the most notable being the ship bobbing (which gives the sense that the entire game is running …
