Doom v1.0 erratic player movement

Post by leilei »

On Doom 1.0 (first shareware release to be precise), at times, it'll feel like there's run mode enabled....randomly, despite not holding down shift at all

Tested with 386 interpreter, 486 interpreter, 486 recompiler, Pentium recompiler, on AMI386 clone and AMI486 clone

Does not affect Doom 1.1, 1.2, 1.666, 1.8, 1.9

Alleviated if you rebind run (default rshift) to another key, like n, so something somewhere is triggering the shift key, which may or may not be related to the spectre vr dos bug

One notable difference between 1.0 and 1.1 is the slightly older DOS4GW (1.94a), may or may not be relevant
