Dreamcast cheat code roundup: Charge 'N Blast, Fighting Force 2, & Ready 2 Rumble Boxing Round 2

Was "Yada yada yada" a fresh reference in 1999?

Aug 16, 2025

My latest trawl through the Dreamcast library has yielded a batch of previously unreported cheat codes for a handful of games:

Charge ‘N Blast: Unlock Expert single player mode.
Fighting Force 2: Alternative level select.
Ready 2 Rumble Boxing: Round 2: Miscellaneous codes.

Below, you'll find the codes, along with technical details on how they work.

Charge 'N Blast (Dreamcast)

Charge 'N Blast is one of the less fondly remembered AM2 games. It was an arcade game first, and was then ported to the Dreamcast in 2000.

There are a couple of known cheat codes for this game. GameFAQs, as of this writing, lists an “Unlimited time and health” code and a “Quick weapon re-charge” code.

I found a third one! At the title screen, enter:

Y, X, B, A, Y,
A, X, Y, A, Y,
B, Y, X, B, A

You’ll hear a voice clip if you got it right. Afterward, the Expert 1P Play Mode item will be available on the mode select screen.

Left: The initial mode select screen. Right: With the Expert 1P Play Mode added.

This code sequence is stored next to the other two, starting at 8c079400 in memory (NTSC-U version).

There are no codes to access them, but this game has some cool debugging modes. If you set the mode index parameter at 8c117700 to 0c, you can jump to them. They let you view objects and models:

There’s also a Stage Select menu that can be accessed by changing 8c117704 to 05 during gameplay. It doesn’t seem to be hooked up to any cheat codes, either — alas.

Fighting Force 2 (Dreamcast)

Various websites report “Level Select,” “Access to all weapons,” and “Infinite Health” cheat codes for the Dreamcast version of this game, but only the level select one works! What’s going on?

I checked and found:

There are no cheat codes that affect health or weapons.
But there is a previously unknown cheat code.

At the title screen, enter this sequence:

Y, A, Down, Down, A,
Y, A, Down, Down, A,
Y, A, Down, Down, A

Seinfeld fans, take note! Weirdly, this is also a level select code. But the level select menu it enables is less detailed than the previously known one (Left, Up, X, Up, Right, Y):

Left: The “Yadda Yadda Yadda” level select. Right: The “Luxury” level select.

On the NTSC-U Dreamcast version, the code sequences are at 8c0edacc. The title screen handler at 8c0c02a0 keeps track of how many correct entries you’ve made.

Ready 2 Rumble Boxing: Round 2

Ready 2 Rumble Boxing: Round 2 already has a boatload of known cheat codes, including ones that unlock characters and others that enable special holiday outfits.

The cheats are encoded like this in the game data:

Lowercase letters u, d, l, and r correspond to Up, Down, Left, and Right.
Space is L.
Uppercase A is R, L.
Uppercase B is R, R, L.
Uppercase C is R, R, R, L.
…and so on.

With this knowledge, we can easily read out all of the cheats the game recognizes. The well-known “Fat boxers” code is:

rrudrB (Right, Right, Up, Down, Right, R, R, L)

Here’s a new one that unlocks Freak E. Deke, Michael Jackson, G. C. Thunder, Wild Stubby Corley, Shaquille O’Neal, Freedom Brock, Rocket Samchav, and Robox Rese4. Enter it at the character select screen:

Unlock eight characters: rluuddC

Some, but not all, characters are unlocked

This code unlocks Freak E. Deke and Michael Jackson only:

Unlock two characters: MJ

This one has you fight Rumbleman in Arcade mode:

Fight Rumbleman: COW

This one resets your progress! Beware; it will re-lock any characters you’ve unlocked:

Zap progress: ZAP

At the title screen you can force the auto demo to start playing with this sequence:

Start auto demo: uudduuddD

And, oddly, you can make the title screen animation restart with this one:

Show title animation: lldudrrT

And you can display the intro movies with this one:

Show intro movies: llrlB

While we’re here, you can get the game to display non-playable characters with hacking. Alter the address at 8c159bf8 before the match loads to change characters. Here’s one called “Shadow” — you can move him around, but can’t punch:

I think Shadow is the boxer shown on the title screen.

This one is Julie Girl. Interestingly, the player appearance codes (fat, thin, zombie) also work for these NPCs:

I don’t think the height/weight stats are quite right for her.
