Current Problem PowerPak Games

Post by **tepples** » Tue Jun 14, 2011 8:57 pm

At this point, the nesdevcompo multicart is a problem PowerPak game. It's a mapper 34 (BxROM) game with 256 KiB PRG ROM. After I discovered that it wouldn't run on a PowerPak, I tried changing the header to mapper 7 and got the menu and four out of five games running. Then I made a test suite demonstrating that mapper 34 on the PowerPak can see only 128 KiB, while mapper 7 can see 256 KiB.

Download BNTest

Nestopia and FCEUX:
Both mappers allow access to the entire 512 KiB, as could be supported by a clone board.

Nintendulator:
Mapper 34 allows 512 KiB, but mapper 7 allows 256 KiB. This is consistent with allowing 4 bits (one 74HC161) worth of state.

PowerPak mappers 1.34:
Mapper 7 allows 256 KiB, and mapper 34 allows only 128 KiB, to the maximum supported by those cartridge boards manufactured by Nintendo.

I've added a fixed mapper 34 to my mapper pack.

Works. Thanks.

EDIT: Can someone celebrate with rule 34 of Deadly Towers?

I don't know if this is an issue or not, I searched on Google and your site. Is there a known issue with megaman3's pause/weapons menu being transparent with NES Powerpak? The only thing that shows up is the "E" and mega's head. It makes the game un-enjoyable and almost not playable. I have tried 2 NES's and 4 different NES roms(including the b's and o's). I own the game, but it would be nice to include it on my Powerpak.

I never heard anything about this... This is really weird! Can you post some pictures?

The Powerpack I bought is brand new (1 week old) would it still effect it?

This is normal play:

Pause menu:

I have no issues with any other game, (Ive played like 50). And as you can tell by my other NES, I'm not b'sing. Does anyone else have this issue?

Nope, it should be fixed. But that is very strange. You try other ROM's?

All of the good tools roms pack for it, including the b's and the one o'. BTW I'm not a fan of rockman3. I need my mega!

That menu needs scanline IRQs to be rendered. For some reason the IRQ doesn't seem to be firing. Did you try different mapper files? Maybe the MMC3 code in your POWERPAK folder is broken. BTW, it has nothing to do with the sprite issue that was mentioned.

Just tried a mm3 rom from D*PER0Ms, and still no-go.

So I should re-download the powerpak folder?

I'd recommend redownloading the POWERPAK folder from retrousb.com and then applying Loopy's latest PowerPak mappers on top of it.

I just tried MM3 with no problems on my PowerPak (not using loopy's latest set of mappers yet either).

Worked!!! I think It just shipped with corrupted mappers. Hope this doesn't effect anyone else.

On a different note:
Now that I have all up to date mappers, Is there any other official or Tegen games I should be worried about not working or having glitches (not counting Castlevania III). Is there a work around for karnov? Any other fixes I need to implement? Thanks so far!!!

BTW wierd quirk now that my first issue was fixed....MM3 flickers all over on the bottom 1/3 of the screen on 1 NES but not the other..... weird.....
Glad to have 2
