FYI, on a real 65C816 the ABS,X addressing mode does not wrap from 0xFFxx back to page zero. This is one of the few cases where 65C816 emulation mode doesn't match a real 65C02, see Bruce Clark's excellent document here:I have also fixed some glitches with the ReCo6502 (at least as emulated in b-em), which would fail to run games built with turbo support and would report nonsense times for the benchmark because Acorn Ozmoo's code relied on 6502-only behaviour (the ReCo6502 uses a 65816).
