Another release
This is a short one for me, a big one for everyone else – for anyone who has a BETA Buffee, PJIT now also works for you. Without any extra boards, without any noticeable loss of speed. For real and you can grab it here.
Home of the new 68K (and other stuff)

In 2020 I drew the schematics for a small board that was going to plug into an Amiga's CPU socket and make it fast. I gave it a name, ordered the boards, and told people it would be done Soon(tm). The boards arrived. The couple of months have since had a few children.
Back in 2024 I wrote PJIT vs Apple, where I explained how Apple's 68K emulator for PowerPC worked, how Eric Traut's "Dynamic Recompiler" improved on Gary Davidian's original, and how much PJIT had in common with it. Since then I've taken that emulator apart, all of it, instruction by instruction, and I have some crow to eat. Nearly everything I said about the Dynamic Recompiler (DR) was wrong. WRONG wrong.
Oh how I've seen my share of bad scalars for old 2D games – from exaggerated CRT effects that make me feel as though I'm on LSD to interpolation routines that make every game look like its made with papercraft. Old school computers present a problem when being displayed on modern televisions that have resolutions significantly higher than the source material. Today, I provide my solution for this.
