A recent comment by Wizzwizz4 about the issue of Building Legacy Software on Modern Systems pointed me to a great question about building 'legacy' software in their contemporary environment even through using within an emulation (*1). I clearly think this is as on-topic as it can get for RC. All parts are contemporary and the problem is exactly the same that would have come up when doing so back then. Fine for me.
Looking closer, this opens another question, as the NS5 he wanted to build in that environment is old by today's viewpoint, but then again from beyond when the emulated environment was actual. So it is basically a backport. Maybe somewhat contemporary, but still a backport. So in conclusion:
Are backports On-Topic for RC?
Like in taking some actual/new program of today (definitely not RC) and port it back to an RC related architecture with an RC related OS and RC related tools?
And as follow up, when would this no longer be true, where's the Rubicon not to cross?
*1 - Which is by the way an awesome project in itself.
