Dragon Warrior II, II, IV on PowerPak?

Xious · Post by **Xious** » Fri Dec 04, 2009 11:32 pm

Hello again,

A PowerPak related questrion this time:

I've been unable to get the PowerPak to run Dragon Warrior II, III and IV...

DW 1 runs perfectly though. Is this a known problem, or are my dumps bad?

Can anybody confirm whether the PowerPak runs DW2/DW3/DW4?

Your dumps might be bad; the PowerPak emulates the MMC1 well.

The PowerPak won't be able to run Dragon Warrior IV, because it uses 1024k of PRG while the PowerPak only has space for 512k. The other ones should work fine. I have played Dragon Warrior II on mine.

DW/Q4 has 4M of PRG ROM, not 8M. (When will it stop?)

Did they mislead me?

Yes, a more complete list would have the board-type rather than the mapper. The same mapper can exist on different boards.

To fix the 1MB DW4 dump, chop off the second 512KB (after the first 512KB + 16 byte iNES header), then change the number of banks to 32 (0x20).

Hex Editors are your friends.

Ah, I see now. I should have checked the wiki. Thanks for the tip.

Uhh....what is in the second half of the ROM that I'd be deleting?

I can easily remove the latter 512K in a HEX editor, but what a simple way to change the registry for the number of banks?

After all is said and done, wouldn't the game code thereafter reference missing data?

Probably a copy of the first half, so you're not losing anything.

Update: I just wanted to thank you all for your kind assistance. I have all four DW titles working perfectly now.
