RetroGuard: Legacy CPU Crypto & Memory Optimizer

Developers targeting vintage 68000, Z80 and other legacy CPUs often cannot achieve constant‑time cryptographic protocols because instruction timing depends on operand popcount and shared RAM stalls degrade predictability. RetroGuard profiles legacy code, rewrites critical operations into constant‑time sequences, and simulates memory contention, giving deterministic performance for secure workflows.

Comment on: Os8088.com: IBM XT OS now has a Browser, CP/M 2.2 with Z80 core and MS Word 1.1a

I‘ve recently tried implementing the Noise protocol on a 7.8 MHz 68000, while it runs in 10 seconds I don’t think there is a way to make it constant time without using addition and running an order of magnitude more slowly :(MULU operations are not constant time but depend on popcount. That has an easy work around just also do the MULU of the bitwise inverse, both instructions sum to a constant cycle count.The brick wall I hit is related to the Macintosh SE ram being shared between CPU and video system. Every few cycles the CPU stalls instruction fetching, which turns the both MULUs together t
