[REQUEST] [32X] Master Code

[Connor]

Hi,
I've been testing some Sega 32X games with game genie codes in my recently bought flashcart and here's the results:

Once the game is loaded, I got black screen but pressing reset the game starts with codes activated.
- After Burner Complete
- Knuckles' Chaotix
- Pitfall: The Mayan Adventure
- Space Harrier
- Tempo

Once the game is loaded, it doesn't matter if you press reset the screen is still black sometimes white.
- Virtua Fighter
- Virtua Racing Deluxe
- Metal Head
- Mortal Kombat II
- Kolibri
- Star Wars Arcade

I think a Master Code is needed for the ones I got black screen.
Can someone help?
Thanks

It's been awhile, but if I remember correctly, 32x games can have 2 different master codes... one for the 68000 (Genesis) side, and one for the SH2 (32x) side. I had tested a few 32x games and found that a single 32x master code worked on all of them. Give this code a try with Kolibri and let me know if it works. Don't know if it will work on your other requests.

32x Master Code

If it doesn't work, please post a code for each of the games that are causing the black screen and I'll make some new master codes.

I've tested Kolibri and the others with this code alone without any other code but still black screen.

Thanks Tony for the reply.

I just tried Kolibri with that master code by itself and it worked fine with Gens emulator.

Will Kolibri play OK without any codes? If so, then you probably need to hack the codes into the ROM with a hex editor, or use a program designed to do that.

[Connor]

Yes, Kolibri works without codes.
I manually hacked the rom using a hex editor and changed values at adress 07CC to 60 and 07CD to 02
Also I tested this hacked rom with Fusion 3.64 and it is working but on flashcart I just got black screen.
That's odd

Here's one more code you can try for Kolibri...

EDIT: Because I can't duplicate the black screen you're getting, I can't help much.

[Connor]

Black screen...
I think I'll have to live with that!

I found out a way to workaround the "black screen" issue.

1) Test the game genie code in any emulator. If it's working go to next step.
2) Patch the rom with the codes (hex editor or any software)
3) Fix the checksum. I'm using Genesis FixChecksum.
4) Test the rom on any emulator to ensure it is working.
5) Copy the rom to your flashcart. Enjoy

Glad you found a workaround.

In case you didn't know, here are some 32x codes/ROM hacks. Some of these aren't here in the db yet...

Here are some more 32x GG codes. Most of these should be in the db, but including the link in case some are missing...

Wow, thanks Tony.
It'll be very useful indeed!!!
