Having trouble getting 2 32x games to work
« on: June 02, 2015, 04:00 PM »
There's a couple of 32x games I am trying to get to work on my 32x using the Mega Everdrive v1 OS 9.

I was able to play MKII 32x version no problem, but I am having trouble with these 2 games:
NBA Jam Tournament Edition
NFL Quarterback Club

It's giving me the same issue of their regular Genesis version. I had to get a patched/fixed version of the ROM to get it to work on regular Genesis. However, with the enhanced 32x versions, the patched/fixed dumps aren't around AFAIK. So it looks like I will have to patch them myself.

Is there any patching programs?

Is there some tool the Everdrive has to bypass this?

Sorry for the late reply.

The patch worked! Thank you so much. Was this just the patch from the regular Genesis version, or did you make this patch yourself?

I couldn't find a fixed rom anywhere, not even the GoodGen 3.00 Romset. Thanks again!

I created the patch, but the hex adresses were found out by someone else (I believe Chilly Willy).

Here is another patch for NFL Quarterback Club:

Again, I would be happy to hear your feedback. I must say that I am not completely satisfied with this patch. There is a short sequence with blue stripes at the start of the game and someone reported that you get a red screen on reset.

If anyone else might try their luck, here are the CPU instructions that need to be fixed in order for NFL Quarterback Club 32x to run. A skilled hacker might be able to translate them to rom adresses.

That patch seems to work for me. There is those blue bars in the beginning, but that isn't even there for a split second. And I didn't get a red screen after pushing the reset button on the Genesis.

But, i think I'm going to stick with the regular Genesis version anyway . I had no clue the 32x version cut out the "QB Challenge" mode which is just ridiculous.

Hi. To fix NBA JAM Tournament Edition (32X) you need open ROM file in a hex editor, go to offset EEC and look for the value 60FE;
change it to 4E71 and save. This hack disables EEPROM saving.

I recommend to use file from GoodGen V3.21 and fix ROM checksum with uCON64 after hack it.
Works great on Mega EverDrive v2! (Tested with Genesis 2 & Sega Genesis 32X adaptor).

Bye  ;)

Any chance the NBA Jam 32X rom hack can be posted again? The link is dead.

Hello.  First post.    I was wondering if anyone has the fixed rom of this game who wouldn't mind resharing.  Thanks in advance.

What is the 6 digit code before "60FE"
