Streets of Rage 2 Hong Kong 97

This is an ips patch for the Genesis Mega Drive ROM file, Streets of Rage 2 (USA).
It is based on that legendary SNES KUSO game “Hong Kong 97”, and is a deliberate KUSO version of the classic Streets of Rage 2. By the way, the characters in the game are fictional and have nothing to do with real people.

Features
-Hack rom “Streets of Rage 2 Double X” is modified on the basis and made to look like a Shmups.
-All music has been replaced. (You can revert to the original music with a sub-patch.)
-Some characters have been replaced.
-Aerial combos.
-Enemies appear more frequently.
-Attack power increases when the player’s health is low. (Throwing remains the same.)
-The XP System increases the performance of characters based on their score.
-Taking the syringe grants temporary invincibility.

Special controls

-A+C or Z to change player character.
-Y or B+C to fire bullets. (6B pad is recommended.) You can change the way bullets are emitted by using the option menu.
RAPID ON Default. Super powerful as it hits the enemy continuously like a machine gun. There is a little gap.
RAPID OFF Little gap, but weak because it hits the enemy with a single shot. If you hit it repeatedly, it hits continuously in the air.
(If you kill an enemy with only bullets, you will not get a score or the number of enemies you have killed. You can get a score by hitting the enemy with a blow and then a bullet.)
-Forward,Forward is Dash.
-Forward,Forward,A is Blitz2
-Up or down + A button to avoid. Basically, avoid up or down.
(Blaze backsteps and Adam stays where he is without moving.)
-When Players are blown away by an enemy’s attack, they can land by holding down the C button. The same operation is used when thrown.

Issue:
-There is a bug that the high-pitched noise in BGM continues to play after you collide with an enemy, but this can be fixed by pressing the start button to pause.

Additional Patch (Apply over HK97 rom)

ADD_Sor2HK97_REPAIR_TO_SOR2BGM.zip:
-Music back to Vanilla Street of Rage 2 ‘s music.

ADD_OnlyChinShoot_SOR2XX-HK97.zip:
-Additional patch to playable characters other than Chin will back attack instead of shot by B+C as the original.

ADD_SURVIVAL_SOR2XX-HK97.ips:
Normally, running Survival Mode causes Axel to appear as enemy and freeze the game. This patch avoids that issue, allowing you to play through to the end. Only Survival Mode is selectable.

VER 1.1 changed
-Fixed a display bug in Chin’s jump throw.(Ver 1.1a)
-Two character sprites have been changed.
-The first character when player selects is now Chin.
-One BGM has been added.

VER 1.09 changed
-One background has been changed.

VER 1.08 changed
-Slightly reduced the invincibility duration granted by syringes.
-Fixed AXEL and ADAM’s BLITZ invincibility being too long.
-Slightly strengthened Mr. Y.
-Fixed ADD_SURVIVAL_SOR2XX-HK97 (additonal patch).
Fix Details:
-High scores was not reflected in the score ranking, and Enemy appearance order was not initialized when restarting the game after a game over. This has been fixed so the game resets after a game over.
-Death animations now display when Chin dies from causes other than being thrown.

VER 1.07 changed
-Fixed a bug that caused the invincibility time granted by a syringe to be reset when using certain moves or being thrown.
-Added one additional patch.

-Fixed a display bug caused by Forward Forward A.
-Added an animation for when Chin dies.
-Added a song to the title screen.

VER 1.05 changed

-Fixed an issue preventing DUEL mode from functioning.

VER 1.04 changed

-Added Recover motion.
-Minor bug fixed in shooting.
-Added an intro.
-Removal of garbage displayed in the title and ending.
-Updated Sub-patch :

Ver 1.01h changed

Written by: 120Pythons - January 4, 2026

This hack is legendary, it completely transforms Streets of Rage 2 into a roller coaster of absurdity and humor. It is impossible to play "SOR2: Hong Kong 97" without laughing or cracking a smile. I am very glad to see it still getting updated with cool additions.

The hacking ability (and humor) that PPI_Akiko displays here is unmatched.  So many things in this hack leave me amazed, wondering how it is even possible this was done in Streets of Rage 2. A lot of consideration was put into this hack to make it a wild experience that takes inspiration from the absurdity found in the SNES "shmup" game of the same name. This ends up feeling like a more complete sequel to Hong Kong 97.

If you like obscure games with absurd themes, this is a must-play.
