Pachi-Slot Monogatari: PAL Kougyou Special is probably the game you're thinking of. If I remember right, the header does correctly indicate that the SA-1 is present but the game never actually does anything with it.

Even if it did use WAI instead of WDM there, it'd still be wrong because DMA halts the CPU until it's finished. The WAI instruction would just stall (possibly forever) until a completely unrelated interrupt happened instead.

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.

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 ...

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).

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.

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 ...

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 ...

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 ...

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 (not to mention that ...

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.

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 ...

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.)
