Edit: delete please, for some reason my iPad double-posted, and tis isn't the only time I've had it happen. Perhaps a side effect of using Chrome's "reduce data usage" feature.

Fusion does properly support mid-frame backdrop changes, but only on a scanline-granular level (which can cause a one-line delay for backdrop changes unless they're done at hblank).

Love the prod just from the screenshot, it just screams classic Amiga/ST demo. Going to download it and watch it on Retroarch, on my iPad

And if you use Charles MacDonald's test ROM (or the same method he used) you can show all "1536" colors including dupes :P Don't guess it's possible with the direct color DMA "mode" to finagle in a way to work with S/H? I know that you can make S/H apply to backdrop pixels, but doesn't direct color ...

Another possible solution could be to only apply bilinear filtering horizontally, while applying nearest-neighbor resampling vertically (and locking window height to integer multiples of 240, with width locked to create an appropriate aspect ratio as Exodus already does in both video modes). This wo...

My First Time Out demo may be a decent benchmark as well, considering I use no interrupts, so I'm constantly polling the HV counter, waiting on specific scanlines to make backdrop and scroll changes. Don't have a binary handy, if anyone goes looking there are two versions floating around, one I call...

I can understand the MS requests more than the other ones, as it would really be more like "emulating the MD fully" than "emulating a whole other system". I also understand that Nemesis is planning on doing so at some point after the initial public release

I was half expecting this to be you having built an Ethernet interface for the MD and running a small webserver on one

Nice technique, Charles. I wonder how it would work if, instead of stuffing CRAM, one pre-loaded 64 colors into CRAM and modified VDP$07 to point to the desired colors. Less colorful, but possibly better for synchronization and/or resolution? I'm pretty sure that modifying the backdrop register bypa...

My converter now supports Riemersma dithering http://sega16.x10.mx/direct_color_converter_v_2.zip To use Riemersma dithering use -i2r or -i3r instead of -i2 or -i3 depending on the color depth that you want. Here is a sample output http://sega16.x10.mx/test3_3r.png I personally think Riemersma dith...

Yeah, I remember one of those players well, it was called Inertia Player. I remember taking MODs I had on my Amiga into school and playing them on school PCs and then telling everyone how much shit they sounded like on a PC lol

As I also wrote over at Retro, I wonder if the click could be abused (like on the Apple II) to generate basic tones or maybe even sample output, without touching the Z80 bus? Not sure how useful it'd be but it was sure useful on the 1MHz 6502, so maybe with a 7MHz 68000 (as well as DMA) it might be ...

If this were a normal LD player you'd be right, but like I mentioned, the problem is that the LA passes the composite signal from the disc through a fairly torturous composite -> separate -> merge with PAC or overlay -> convert back to composite process. The GameSX article claims that the s-video m...

Depending on the content that the rot obscures, it may be possible to manually repair it (or, if it slightly differs each time it's played, it'd be worth taking multiple captures of affected segments until the rot averages out).

RGB won't really help in terms of video capture, since the disc stores composite video and the only relatively cheap RGB capture card I know of is the SweetSpot (link currently down, unfortunately), but with the RGB mod essentially just decoding the composite signal, best to just capture the composi...
