I got 8 layers of strips moving onscreen. Now I need to turn these strips into checkered squares. :roll: Something I forgot the 68000 had was a MOVEM instruction that could move several registers to memory in 1 instruction. 1 instruction, but a metric fuckton of cycles. Worst case 18+4n. I wouldn't...

May I also remind you that people had no issues emulating "Old vs. new SID" on the Commodore 64. Not emulating OD2 for this one reason seems like a very fabricated excuse You 're right, but only two case to take in account vs how many for genesis ?? :P For now it's not like you have a pre...

Not emulating OD2 for this one reason seems like a very fabricated excuse - There's so much more wrong with emulators even breaking effects that *don't* rely on this debug register

Video memory isn't mapped to processor address space. You have to do all reads and writes through a port, or if you do DMAs you still have to wait for that to complete - so always imagine a massive overhead on top of all graphics calculation.

Here is a 50fps capture of the entire demo: http://mdscene.net/.stuff/od2_h264.mp4

Wait for the write-up.

?????!??!?!

I'm part of the programming team, of course I know how it works.

You know absolutely fuckall

They are, but for starters 'Muricans commonly use composite video for watching and modding the console to 50Hz output does not correctly adjust the color burst frequency for the signal so your picture will be in black and white (It's neither NTSC50 nor PAL )

Oh my fxcking god. Never have I seen a nickname ring true in so many ways.

Here you go.

On a different note - My poor CPU is busy reencoding the entire demo for something more suited for uploading (the original was a 11GB ProRes file ...)

What are you talking about? The fractal rotozoomer is running at 50 fps.

Or are there ways to lock a Genesis so hard that it can't even call the bus error handler?

Yes, because the VDP controls DTACK... :/

Are you literally trolling? The Amiga is a computer designed for things like this. It has a ton of custom chips devoted to fast graphics, overhead-less digital sound and 512KB+ of memory - oh, and it isn't tilebased. Specifically talking about the launch Amiga, not the later ones. It's a 68k at the...

At which point I shall congratulate you that you have replicated one effect in isolation.

Guys, you're freaking hilarious and just absolutely full of it. The salt level in this thread is insane. :) The allegations are hilarious. Custom chip? Prerendering? Playing an animation? This is not the SNES and we most definitely don't need half a dozen Super FX, DSP or other helper chips to do so...
