AcheronVM is a small, customizable 16-bit software CPU for the 6502. It has thrown out traditional models to pursue all 3 competing aspects of density, speed, and power solely from within the context of the 6502's tradeoffs. Notable features include a unique hybrid register model, try/catch/finally support, pointer-offset addressing modes, easy instruction set modifications, and a purely ca65 macro-based implementation. This talk spans its design, implementation, and use.
