In case your DM250 ran OpenBSD too fast, I made armv7 able to boot from a softraid disk so you can have a fully encrypted eMMC root.

I ported enough of NetBSD's armv7 MP code to OpenBSD to do a 'make -j4 build' on my DM250X.
It brings a full system compilation from ~5.1 days to ~3.5. Compiling LLVM is still multiple days :(

Did a "soft" rework of how graphics in my game are handled, from tile sources to an atlas. More than 128 sprites exported and reimported. Took me 4 days! Saved a single Draw call lol

This error message in Steam is amazing, because it's from back in 2019 when support of IA-32 (Intel's main architecture from 1985 to late 2000s) finally ended on Macs.
But... since late 2020 Macs use Apple Silicon which can't run Bootcamp (as the message suggests).

why would unnamed arcade rhythm game force me to reverse ARMv7 code *again* except this time it's worse because it's userland lagdroid stuff instead of nice pretty boot code like on the Wii and iPod classic and NOKIA Lumia 800 like i'm used to.

OK, so here's a few words about different kinds of timers, why SYSTICK is good for what it was designed to do and crap for the modern tickless world, and how I implemented embassy-time for the Armv7 Generic Timer.

This V8 upgrade was particularly difficult and overdue but had to be done for v24, and it finally landed 🎉 Now v24 can finally progress after missing the April 23 deadline github.com/nodejs/node/...
Some explanations about why it took so long from the parts I know (@targos.dev probably knows more)

I've started publishing semi-daily updates on my website of my hacking on the Pomera DM250 to try to get OpenBSD running on it. First up is getting u-boot updated and working enough to be able to boot OpenBSD's armv7 EFI loader, then I guess it's endless driver porting.
