I've been looking around for information on various Famicom games that were ported from earlier PC titles, specifically those made by Enix (Door Door, Portopia, etc.). Finding decent technical info (in English) on Japanese PCs is tough, but I have a question that likely applies to several Z80-based processors from that era.
In this YouTube clip (skip to around 2:45) of Portopia on the NEC PC-6001/6601, graphics are drawn in a kind of 'vector-style' -- individual lines and shapes first, then color fills. It's remarkably slow compared to the NES. What is this rendering mode called? And what is the technical explanation for this technique? The Japanese wikipedia article on the PC-8801 appears to have a paragraph explaining the slow drawing mode, but the English translation is too poor to figure out what's going on.
Any info is appreciated. I don't know much about early PC capabilities.
