I actually had a 8086 back in the day, it was this thing:
This model was produced in 1988. I actually learned to code in this thing, after being taught the basic notions of BASIC by my
aunt* in her ZX Spectrum. It ran an earlier version of MSDOS, and could run GWBASIC (the one with line numbers) and microsoft's QBASIC/QuickBASIC. It ran at the magnificent speed of 9.54mhz in top speed, and was able to display 4 glorious colors in CGA mode: black, white, baby blue and bubblegum pink (with an alternate palette of piss yellow, puke green and crimson red). Pascal and C were available if you managed to find a compiler in the pre-internet era, and they performed faster than BASIC at the cost of being much harder to learn and requiring compiling, which was incredibly slow and tedious.
*Yeah, I owe my ability to code to a woman. So much for a misogynistic cis shitlord. Also, oh my god, there were women doing code as a hobby in the 80s! go figure!
Now, you can write this off as powerleveling, but I am aiming for informative here. It is possible Wu actually owned one based on those specs and time. However, I call bullshit, if you learn to code in such a restricted environment, you learn to optimize, because every single wasted instruction was noticeable. Just a simple
for loop to initialize an array of say, 200 integers, would take a couple seconds to complete, as opposed to fractions of a milisecond like today. RAM was also very limited and a large portion of it was eaten by MSDOS and stuff like the mouse drivers. Documentation for those languages was written for professional adults and required huge nerd-om to make sense of them, often in massive books that acted as pretty much an API reference. Since there was no internet or Stack Overflow, it was difficult to find more information or help.
You were on your own and there was no sugar on top.
Now, we know Wu doesn't know how to properly browse Unreal Engine's class documentation, as seen somewhere in this current thread, and asks for help constantly. We also know he doesn't know how to optimize, throwing dynamic lights into scenes with models with huge polygon counts in a game that already runs slowly in the intended hardware. He doesn't use the proper tools for the job (mac's notepad to edit xml instead of a code editor with syntax highlighting, or paint for screenshots, etc). Not to mention, the bizarre choice of a cinematic, badly optimized, fully 3D game for a platform such as the iPhone circa 2013.
Now, let's throw the jargon away and say it blunty. All evidence about Wu's ability to code, points to not having any idea of what he's doing. If that story was true, he'd be far more wise, would have made more sensible choices, and more importantly, would have elaborated on his coding skills over time, because in that age, if you had the commitment to learn with the limited resources, that means you were
serious about it. It just doesn't check out, and his interest in creating games seems rather recent given his (mis)use of jargon and general lack of wisdom in the field. My bet is that he just hogged the house computer to play old DOS games, if at all. It's most likely he was just playing his Nintendo (which he said he did in other stories, the Mario 2 story). It simply doesn't match.
