Open in NOSE - Select Rom from the headings at top - apply hack - free bytes - then try both available options.

I know they work for 92 if that's what you're looking for.

Hot hex-sex. What a great lexicon of editing knowledge.

I'll create tutorials for all the 30 team rom stuff, eventually.

Noticed how the roster updated roms have different fonts as well. Anyone like to volunteer to throw a quick tutorial together on that? Much appreciated

I think the fonts are just graphics, so if you can find the font graphics in the ROM in tilemolester, you can just edit them there. I don't know where they are, though.

30 is the limit.

I have an interest for a Rom with more than 30 team, why is 30 the limit ?

Can someone explain me please

That's how wboy made it.

It's a complicated process moving all the data around to enable extra teams, and linking up the additional graphics and palettes. Only wboy knows how to do it, and he may have settled on 30 teams (actually I think there are 32 teams with the all star teams) due to some limitation.

Similarly, when I made the SNES NHLPA'93 64-team ROM, it would have been easier to just do 32 due to a graphical limitation (the video memory can only hold 32 full team banners at once), but I did some wacky stuff to get around the limitation (broke the banners up and made it re-use parts of the banners multiple times).

I would like to, but it's time-/motivation-dependent.

within reason, how do I motivate you? I'd be willing to help with the tedious parts.

I don't think anyone can provide the motivation. My motivation is for the community in general, that we'd have a SNES ROM that could be edited to get current rosters and logos. This could bring more people into the SNES community, which would start up leagues, and whatnot...

well, does it hurt? I'm serious in offering my limited skillset for assistance. the league isn't likely to go back to less than thirty teams any time soon.

refer to the links above and follow these ones:

Disable or lengthen the Goalie play stoppage whistle - (Feb 6 2010) - clockwise, smozoma

-- use the disable method

Let the goalie roam farther with and without the puck - (Feb 7 2010) - smozoma

-- I added another case in the post showing how to let the goalies go anywhere

nope

I should make a 'how to use these hacks' guide, showing how to use a hex editor... although it's pretty simple if you give it a try (open the file, go to the location, change the value, save!)

i tried useing the hex editor last night, i failed. rom wouldnt start after i saved. def did something wrong, probably wasnt changing what i was supposed to be changing. maybe i'll mess with it more tn.

If you use the original NHL94, it won't work because there is some code that detects if you modify the ROM (using a 'checksum'). But if you use any other ROM, it'll be fine because they'll have :)

Or, you can manually kill the checksum in the original ROM using this technique:

OFFSET: 0300
OLD VALUE: 4EB9 000F FAC0
NEW VALUE: 4E71 4E71 4E71

holy s**t i did it! thx smozoma!!!!! its waaayyyyy more fun than i thought it'd be! i'll post it later fur sure :D

couple notes:

goalies can take each other out but they BOTH fall down and they look like regular laid out skaters till they get back up, its pretty funny.

i can only take the goalie out of the crease if the goalie is in view :( any way to change that? i need moar goalie!

Haha, that's awesome. I never thought of what might happen if they ran into each other...

I've noticed that, you can't really do anything with the goalie control if he's not on screen.. I have a rough idea of how disabling that would be done, but I don't know if I'll ever do any more hacks to be honest.. time/motivation just isn't there.
