2.0, I believe. I guess I'll have to look into updating it if/when I ever get around to doing anything else with that code.

Re: How many fullscreen 256 colour images?

I wrote an Exomizer decompressor for the SNES a few years ago: https://gist.github.com/devinacker/b3658c6c671bdf3abf58da33f15ef284 It's a bit larger than the stock 6502 version, but uses 16-bit operations where possible and also has some other options for tuning performance. Currently it depends on ...

Re: Are there any disassemblers for weird 6502 variants?

MAME's 'unidasm' tool with the "-arch r65c19" option should do what you want (at least at a glance, the instructions it supports seem to match the table in the documentation you posted).

Re: bouncing DVD logo demo :D

Very nice work! This is making me want to brainstorm some more SNES sizecoding ideas, it's something I haven't really thought about in a while.

Never was. Backporting emulation improvements has been a goal for the entire history of the project.

Re: WAI instruction

An ABORT always calls the interrupt handler, but does not end a WAI instruction But that is the thing, the datasheet states the ABORTB does end a WAI instruction, when I is set. So the I does modify behavior other than IRQB. The ABORT does technically end the WAI instruction, but after the interrup...

Re: WAI instruction

To try and put it simply: An NMI or RESET always ends a WAI instruction, and always calls the interrupt handler An IRQ always ends a WAI instruction, but only calls the interrupt handler if I=0 An ABORT always calls the interrupt handler, but does not end a WAI instruction The ABORT behavior is diff...

Re: 65C816 native to emulation mode switch

D remains untouched in emulation mode, but behaves a little differently in emulation mode: indexed addresses will wrap-around within a single page if D is page-aligned (i.e. the lower byte of the register is zero), otherwise it behaves the same as in native mode. Here is the implementation in bsnes,...

Re: NFT/Blockchain ROMS

What actual tangible benefit is this supposed to provide to anybody in the nesdev community? You mention three things behind the idea: "digital collectibles", which people are somehow supposed to believe are "collectible" even though digital goods are all trivially duplicatable (...

I assume snesmod didn't touch any of the ones that were below 32kHz, but I'm not sure if it automatically downsamples anything above that or not.

Re: SNES Music Pack 1 by Resistance

It does look a bit wide now that you mention it, though; I guess I just got accustomed to my USB captures looking that way. I'll have to fiddle around with it next time I'm recording something. Anyway, not to get on too much of a tangent: Also those samples are really high quality. Are they all 22-3...

Re: SNES Music Pack 1 by Resistance

I'm not really sure why PAL aspect ratios are relevant, considering I recorded that video off of an NTSC console via S-Video.

(as for why the video has the aspect ratio it does: beats me. I just record what my capture device gives me.)

Re: BS-X Satellaview Broadcast Frequency?

Yeah, it should boot up fine without a memory pack inserted, you'll just get an error screen if you actually attempt to load up a game.

Re: BS-X Satellaview Broadcast Frequency?

The Satellaview doesn't listen on satellite broadcast frequencies at all. It only reads the bitstream output from an external satellite receiver, which you had to purchase separately. Theoretically, that bitstream can be generated by anything, which there has been some experimentation with somewhat ...
