The Motorola 68000 was a popular 16bit CPU of the late 1980s, perhaps best known for single-handedly powering the Apple Macintosh. It was also used half-a-decade later (it appears they waited for costs to come down) by the SEGA Genesis, so naturally LibRetro's emulator must implement it!
It looks like LibRetro's entire SEGA Genesis emulator was written around what *was* a preexisting "Musashi" 68k emulator.
It includes a variant for "sub-CPUs" which I believe is irrelevant to LibRetro.

I spent way too much money obtaining this on eBay, because I couldn't find my copy. Must have thrown it out decades ago because it didn't match any prototype we built.
The Jaguar System ERS, ca. 1989
Jaguar/Hurricane was the 88110 RISC desktop system Apple never shipped. Tessaract was a 601 system with BLT bus slots. TNT (The New Tessaract) was the 2nd gen PowerMac with PCI instead of BLT slots. We only ever had a couple of semi-functional 88110s for Hurricane before the PPC Deal of the Century happened in summer 1991.

Sad that most of the "advanced" stuff in Jaguar, like pre-Quicktime "multimedia" woudn't have made much difference in the marketplace and it was too early for ubiquitous high-speed networking. It also was going to support up to four 88110 processors.
Oh.. it was also tied at the hip to Pink 😞
About the only architectural thing that survived was descriptor-based DMA that was part of the Mazda I/O engine.
I need to write the whole history of this someday. You can find tons of info on PDM (the first PPC Mac to ship) in places like Gary Davidian's CHM oral history. This is the system he talks about that he thought would never ship because it was incompatible with existing Mac software.
We could have ported Unix to it, but that was never even considered either by us, or the team that was working on a 88110 server in Networking and Communications. Theirs was called "Shiner" and was obviously different from what they eventually shipped with a PPC in it.
holy crap: mastodon server does not support domain name changes. 😆
i now have to give some serious thought to migrating dialup.cafe -> dialup.party
it would mean setting up a new server from scratch, migrating users to the new server, and losing all of their post history in the process. i am truly dumbfounded at how bad this architecture is.
Security is primarily a social problem.
You can't google pixel grapheneOS your way to perfect digital security.
It is here.
And with it I finally got a SilverLink, now I can experience the glory of connecting calculators that don't have USB to TiLP on Linux even when my machine lacks a serial port.

here is a screenshot of the libreboot build system, lbmk (LibreBoot MaKe) building some roms.
the meme to the left of it is for illustration.
i have some massive improvements planned after i get my current batch of minifree orders done this week.
big changes planned for lbmk. big release planned for december 5th!
the changes will be so dizzying.
agenda:
* chromebooks. lots of them.
* more kabylake thinkpads
* alderlake (and possibly newer)
* tianocore and linux payloads
* more

A searing hot shower, fresh unwilted vegetables, new old shoes and a spray of fragrant golden leaves all conspire, during the fretful hours of the night when a few sleepless neurons can't seem to riddle out why the wind is not pivoting us around the anchor, to reassure me that we have indeed returned and are once again docked in Victoria.

FUN FACT: you can bypass CR50 on a chromebook. it's a bit naughty but it can be done.
i recently did this on *my* chromebook, which is a gru_bob model; i also recently flashed a gru_kevin but that one was pre-cr50 and just uses a write-protect screw.
i'm investigating a minor bug on rk3399 with u-boot (coreboot payload) related to usb-pd; powered usb-c hubs don't work. need to enable something in u-boot
that's how you unlock the flash without a cr50 dongle.
new guides for libreboot.org soon.
"Instead of sending public money to distant corporations, funds stay local and support IT jobs for regional developers and entrepreneurs. The use of open-source #Linux distributions also extends the life of existing hardware and reduces e-waste, which proprietary models can exploit for unnecessary spending."

LibRetro's SEGA Genesis emulator can optionally embed & integrate LibCHDR to (in part) provide alternatives to reading from an actual CD. Some of which are anachronistic for the SEGA Genesis.
This includes a utility to aid it in reading bits, rather than bytes, from a file.
Another utility combines XOR with lookuptables to compute & verify (extended?) error-correcting codes found on CDs.
There's some utils for converting MSF & LBA addresses.

I dreamed (literally) up a new format: MINI-CED!
It was a standard Capacitance Electronic Disc (you know, RCA's also-also-also-ran 1980s home video format?) but in a 7" single size.
Annoyingly this wouldn't work in real life, because to fit in the player you'd need to use a full sized cartridge anyway
