The v2 version is identical in gameplay but includes a new edited copy of the disc image file 'script' containing unclothed bitmaps that replaces the semi-nude girlfriends' textures from the first version. The second major release of the Hot Coffee mod, often referred to by its version name Hot Coffee v2 to differentiate from the original, was released just days after the original and largely replaced it. The mod was first released for download on PC in Jthrough and was released for the PS2 and Xbox soon after. The mod was also made possible on the console versions by changing the bit inside a user's saved game file or by using a third-party modding device.

The PC mod itself is only an edited copy of the main game script file ('main.scm') with a single bit changed. The files containing the mini-game content were soon discovered and Patrick Wildenborg (through his online account PatrickW) released the Hot Coffee mod to enable it. The sex minigame feature was disabled from the game before release, but not actually removed. 'Coffee' is usually offered once Carl reaches a certain relationship percentage, although if he has collected all the oyster pick-ups, coffee is offered automatically, even after the first date. Since the camera is outside the house, all of these sounds are severely muted. If the player agrees, the camera stays outside, swaying back and forth a bit, while moaning sounds are heard along with various comments from Carl and his girlfriend. In the unmodified game, Carl takes his girlfriend to her front door and she asks him if he would like to come in for 'some coffee'.

The name 'Hot Coffee' refers to the way the released game alludes to unseen sex scenes.
