You're welcome!

Yes! I only tested them in Nestopia though.

[A bunch of silly stuff about not being able to run the script.}

Never mind, I figured out how to use it. Thanks for the super-helpful script, Shmerl!

I found a way using "misanthroat" and "blakstar" post. (Thnx both of you!!!)

Using bash in Win10. Use following commands 1 by 1.

NES ROM Header

dd if=cc.exe skip=1041776 bs=1 count=16 > nes_header

dd if=cc.exe skip=124272 bs=1 count=131072 > castlevania

cat nes_header castlevania > castlevania.nes

dd if=cc.exe skip=255344 bs=1 count=262144 > castlevaniaii

cat nes_header castlevaniaii > castlevaniaii.nes

dd if=cc.exe skip=517488 bs=1 count=393216 > castlevaniaiii

cat nes_header castlevaniaiii > castlevaniaiii.nes

dd if=cc.exe skip=910704 bs=1 count=131072 > contra

cat nes_header contra > contra.nes

dd if=cc.exe skip=1041792 bs=1 count=131072 > jackal

cat nes_header jackal > jackal.nes

dd if=cc.exe skip=1172864 bs=1 count=262144 > superc

cat nes_header superc > superc.nes

After this repair the headers with this:

You're welcome!

Thanks for the script dude! Works perfectly.

You're welcome!

I actually just posted a new thread, about trying to get a re-translation rom hack working with the GOG version of Castlevania 2. I was wondering if you have any thoughts on that?

(sorry, I'm not able to post links)

I'm not familiar with it. May be reach out to the author of that hack? If you can read the code for it, check what it's doing. Like modifying the header (or expecting certain header?).

The way extraction script works is adding some pre-defined headers to the blobs of the games from the archive. May be that hack just expects something else.

Ok, thanks. I will reach out to them and see what they say.
