Re: Questions (mainly) about SNES Audio

Judging by the hosts' recent twitter history, it's seems highly likely that an upcoming episode of Retro Game Audio will be a deep dive into SNES audio. It's a pretty great podcast, especially their latest couple of shows about the FM synthesis on X68000 and the VRC7.

Re: All avaliable (/unavaliable) options for creating tilema

No binary? :? Yes, with help from ARM9 I just recently got a build system for Windows up and running. These should work (not sure about what runtime libs may be needed that isn't shipped with the OS, but Windows is usually good at telling the user about any missing standard DLLs). https://github.co...

Re: All avaliable (/unavaliable) options for creating tilema

My graphics tool (SuperFamiconv) does most, if not all, of the things you ask for. I'd be happy to add what you think is missing; it's use cases like what you describe I want it to be good for.

Re: Questions (mainly) about SNES Audio

True, although several MIDI standards exist which also defines sounds. Many of these standards were commonly supported in games both on Japanese and western computers from the late 80s up to the mid-90s (and resulted in some pretty awesome soundtracks, too!).

Re: Questions (mainly) about SNES Audio

I read on Wikipedia ( https://www.wikiwand.com/en/Nintendo_S-SMP#/DSP ) that the SNES has 8 voices, instead of 5. But the page doesn't explain any deeper. What waveforms are allowed? Is each voice's waveform fixed like the NES, or customizeable like the C64 ? The Wikipedia article does a pretty goo...

Re: SNES (Playstation) finally plays CD-ROM games

The SNES-CD was certainly a case of too little, too late even at the time of its inception. As a curiosity it's pretty awesome, but that's the extent of it if no prototype software ever surfaces. I guess we can only hope that some more information about the whole project comes to light at some point...

Re: Some basic questions...

It should be easy enough to add such a mapping to SD2SNES and bsnes+, so for development work we're covered.

Ah, true, I didn't think of the I/O ranges in bank zero... So yeah, that'd be awesome to jump to in theory at least.

Re: Some basic questions...

Is there anyway to get IRQs to fire immediately to fast ROM region? The interrupt vectors are 16 bit words pointing to bank $00, so no. One common pattern is to have an indirect long jump at that address, so the vectors can be reconfigured via software and consequently you can also spend as little ...

Re: We've been called out

And the SNES is dirty in the sense that you need to fiddle with banks all the time (not needed on the MD due to its 16 MB linear address space) and Nintendo was stingy with register and memory bits, forcing programmers to fiddle with bits too (they e.g. crammed sprite coordinate bits together where...

Re: We've been called out

Sorry about opening this whole PAL vs NTSC can of worms. I really only wanted to point out that regardless of what TV system you grew up with you're likely sitting in front of a fixed 60Hz panel right now (unless you're really fancy ), and so are most people that stumble on a video of the latest dem...

Re: We've been called out

Why PAL? a.) see http://static.diffen.com/uploadz/thumb/f/ff/PAL-NTSC.svg/610px-PAL-NTSC.svg.png then note that most SECAM countries also support PAL, yes you are that tiny red bit, yay you b.) When you make a demo, you want the best machine you can get, PAL machines will slaughter a NTSC machine. ...

Re: We've been called out

I've never encountered a european TV with SCART input that doesn't do both 50 and 60Hz video if fed an RGB signal. I've never encountered a TV with SCART input. SCART isn't really a thing in the USA. Yeah, my post was written from a european perspective. The SCART connector was even called EURO/EUR...

Re: We've been called out

How easy is it to mod a TV to accept a modded console's output? TVs sold in the United States typically aren't specifically advertised as multi-system compatible. Are you sure about this? I admit I don't know a lot about consumer TVs, but pretty much any CRT TV sold here since around the mid 90s (n...

Re: We've been called out

Absolutely amazing demo, quite possibly the best stuff ever to grace a stock mc68k machine (in addition to obviously being a top contender for best console demo ever). To all the armchair critics pulling the tired "well done but nothing technically impressive" card, there is only one respo...
