"NES-patches" for VS-games?

But mapper-hacking would loose the dip-settings? Unless you software-emulate them aswell...

Even if you're using 1 KiB for the free-play and palette patches, that still leaves 7 KiB for a service mode menu for setting DIP switches.

Please forgive as, once again, i don't have enough knowledge to truly help.

Instead of using a save ram hack for Ice Climber why not just expand the thing from 16k to 32k? As I understand you wouldn't have to change the "mapper" at all.

UPDATE: Crud. I was looking at the normal cart version and not the VS. size

It's already 32K.

Yeah. I missed that.

However, what is taking up double the space for the VS. version?

On this list:
http://tuxnes.sourceforge.net/nesmapper.txt

NES Ice Climber is listed as
Ice Climber 16k PRG / 8k CHR H ---- (0)

VS Ice Climber is indeed 32k
Vs. Ice Climber 32k PRG / 16k CHR V Unisystem (99)

The graphics, sound and levels can't be upgraded so much to actually take up twice the space, right? Wouldn't there be some padding imbedded somewhere? Couldn't one use the filler space?

There's no filler space that I can see (perhaps there is, but it may be random bytes of garbage data)..

Does any debugging emulator supporting code/data coverage logs support this game? And has anyone played through it to get a good CDL?

FCEUX (I think) has Code/Datalogging. But I don't want to play all 24 levels..

Working on VsExcitebike now, 75% done. This patch will fit within the ROM itself.

All 24 levels?

Obviously, you haven't played very far in VS Ice Climber. After clearing several levels, you get the Super Bonus Stage, then get to select from a different set of 24 levels. Then after clearing some of those, you're sent back to the first page.

Wow, cool, didn't know that.

Ice Climber is the first game I ever played on the NES and it have a special place in my 8-bit heart.

A bit off topic but, has anyone ever tried creating a level-editor for Ice Climber? That'd be cool..

Here's a patch for Excitebike (VS). No need for a battery-hack this time.

Insert a coin by pressing "A"-button.

I just completed a patch for Pinball (VS), but it looks like the emulators I use (Nintendulator/FCEUX) prevents it from working 100%. I think they use checksum to determine if it's a VS-ROM or not and with my patch the checksum obviously doesn't match. :/

EDIT: Link for Pinball-patch on my first post...

Try mapper-hacking the games to CNROM. Then you need to change any part where it tries to access a VS register.

Just updated my Pinball hack to CNROM instead.

Pinball hack has a minor problem. When the demo presses A, it inserts two coins
