Beep! Mega Drive
(February 1993)

The screenshots in this preview seem to match up with the final game, other than one minor exception:

Preview	Final
This screenshot shows a trash can as you enter the first round's last area. The final version removed it.

Mean Machines SEGA
(Issue 6, March 1993)

A two page preview which features screenshots from a work in progress version of the game. The main things of note with this preview is that the life bars don't appear to be working properly -player 1's amount if health is the same in every screenshot. It appears that the life bars for the enemies appear where player 2's life bar should be, as seen in the screenshot with Sodom. Most of the enemy life bars have Cody's portrait on them. The scores don't look like they're working yet either, in almost every screenshot the player's score is at zero, and in the Sodom screenshot, it's at a ridiculous 9,000,000! The high score is also set at 9,999,999.

The bottom of the first page makes a cryptic mention to the arcade's "naughty" mode. It appears this is referencing the Japanese arcade version, as Jessica does appear in her underwear in that, but not the overseas version. But then it also says that the female enemies are more "provocative", however there's no difference with Poison and Roxy between the Japanese and overseas versions of arcade Final Fight. As far as I know there is no hidden mode in the overseas versions of arcade Final Fight.

Beep! Mega Drive
(March 1993)

This preview contains screenshots that look like they're from the final version, however there is one big difference:

Preview	Final
The screenshot of the time attack mode results shows Haggar in a different pose. He was redrawn for the final version.

Mega Drive Fan
(March 1993)

A big four page preview from this Japanese magazine. The screenshots appear to mostly show a near-final game, but it does have that early Haggar time attack image that was seen in the Beep! Mega Drive preview. It also one another oddity:

Preview	Final
Rolento is spelt "Rolent" in this screenshot. In the final version, it's "Rolento", like it was in the arcade game. Simple mistake? Abandoned tie-in to the Final Fight 2 spelling? Who knows.
