Re: SuperRT - realtime raytracing expansion chip

So how optimised is this compiler when it comes to the performance of the compiled program? The nature of the instruction set (more-or-less one instruction per primitive) means that it's fairly close to "optimal"... or, if you want to look at it the other way around, it's pretty hard for ...

Re: SuperRT - realtime raytracing expansion chip

Why were you trying to avoid widescreen? I wasn't trying to avoid widescreen entirely, just that I felt like a very widescreen aspect ratio would make it feel "less SNES-like". It was purely an aesthetic decision, really. But I thought you just did debug through HDMI. Is the overlaid debu...

ShironekoBen is purely a handle formed because my real name is often taken on sites. And to answer some of the technical questions: Is it possible to use this c...

SuperRT - realtime raytracing expansion chip

(this is my first post, so apologies in advance and please do just let me know if I've inadvertently broken any forum rules!) I'm something of a fan of doing silly things with retro hardware, and as the SNES holds a very special place in my heart, whilst casting around for ideas for a project to do ...
