Esp

An internal ESP that works by hooking the game loop responsible for calling world-to-screen and loads a custom vm_main function that prints an "X" over the current location before rendering the entity.

idkmybffCoD

A multihack for CoD1 that features a wallhack, chams, full-bright, no-scope, no-fog and internal ui.

Internal-OpenGL-Wallhack

A OpenGL wallhack that works via hooking CoD's internal call to glDrawElements while displaying players and modifies the call to disable depth testing.

Internal-Wallhack

An internal wallhack that hooks CoD's syscall function and adjusts the render flag of entities that pass through for rendering.

No-Recoil

A no-recoil hack for CoD single-player that works by removing the instructions for aim being punched up while shooting.

OpenGL-CountMonitor

A utility to log the counts of displayed entities to help isolate specific counts of player models.

OpenGL-Wallhack

A wallhack that uses the glTexCoordPointer method to achieve great results without logging counts.
