The impossible, once again possible

Here’s Virtua Racing for the Sega Genesis/Megadrive with the “SVP” polygon chip in MESS, based on a submission by notaz.

Naomi, now more than ever

Samuele Zannoli is at it again. Here’s a few SH-4 bugfixes and Naomi I/O board improvements later…

I’ve also further improved the Naomi audio emulation. No new samples this time, sorry.

The noise: brought

A couple of nice coincidences linked together today. First up, I submitted the AICA core to MAME so Naomi now has sound. Secondly, MAME Italia dumped the Naomi game Toy Fighter, which successfully gets into it’s test mode (gameplay doesn’t work). Test mode includes the sound test, and here’s what it sounds like, with the “load times” cut out to make things managable.

Noise patrol

I’m working on emulation of the AICA (the Dreamcast/Naomi/Hikaru sound chip) behind the scenes with kingshriek and Deunan Knute (the Makaron author). Since AICA is basically an SCSP with double the voices and a few feature tweaks the obvious basis was MAME’s now reference-quality SCSP emulation. That’s allowed us to get to a pretty good state in a short amount of time. The ADPCM sample type isn’t quite right yet, but the basic functionality and effects DSP are working.

Music to bleed Aaron’s wallet fix bugs to

You may think the likes of MAMEdev and MESSdev are weird because we have a hobby that somewhat mirrors what many of us also do professionally. You’re probably also looking for good new music. And now you’re confused as to how I put those things together.

A little help from my friends

Some small progress. Big thanks to the hero of Chankast, the man they call ElSemi for some technical details. (You’d think Sega would have given up on throwing random weirdness into their hardware by this point. You’d be wrong).
