I've revamped the GBA article with new info about backwards compatibility, hidden modes in the PPU (which I suspect they were meant for a stereoscopic mode, a la 3DS) and the wonders of the Link cable. This is to prepare for an upcoming book release. www.copetti.org/writings/con...

Is there anything more notable/interesting than github.com/xairy/raw-ga... for emulating USB devices locally?
Think loopback - I have an emulator which is supposed to provide an USB device to the host it is running on (guest->host device emulation, as opposed to host->guest device passthrough).

If you're still using Twitter/X in any capacity get the fuck off now. Cut ties entirely. Any following you have is not worth it. For any reason.
Every piece of reporting I've seen on this is drastically understating the scale. These are from Grok's replies within a single minute. Time-to-reply is degrading because it has such a backlog of NCII/CSAM requests to fulfill. Conservatively I estimate it is producing more than 5000 of these per day
