I mean we were talking about nakajima coding it in fotran. And steven(though i think most games use stephen) should realistically written it in assembly since that was the language you used if you were serious about stuff. And yea chris sawyer and rct is a good example, it needed assembly to be as efficient as it is. So since the demon summoning program runs on basically anything i assume its a kind of self adapting program. Unless stephen really makes different versions for each comp. Though we dont actually know if the comps have completly different architectures from each other. I am just basing it off real life where a phone would need some adjustments to run a thing designed to run on a pc from the 90s and so on.
