Patching MechCommander's "left arm bug" for fun and profit

23 days ago

MechCommander 1 has a bug where large weapons are all placed in the left arm, causing significant firepower loss if that arm is destroyed.
The bug was analyzed and fixed by modifying the game's assembly code to properly distribute large weapons across multiple locations.
Weapon classification was updated to correctly categorize weapons from the Desperate Measures expansion as 'large' instead of erroneously 'small'.
The fix involves hex editing the game executable at specific addresses, and a patcher tool is available for easier application.
Additional quirks like inconsistent visual arm loss and UI discrepancies were noted but considered out of scope for the fix.
