shithub: patch

ref: 7caa9585434c771bea1aaf6d3317b969df5afa9d
dir: /doom-limits/

View raw version
this lifts a bunch of limits in the engine for stupid bullshit wads that
don't honor them. this should not be merged, ever. these inflate a bunch
of arrays, and make doom use much more memory.
. savegame buffer overflow: for maps that are too large; does not work
  correctly, loading several times in game will eventually crash (will not
  corrupt anything though)
. demos can desync when raising max intercepts and spechits, so left alone
  despite possible problems
