Centipede Protection

[ajcactus]

Hi

I have a problem with the game "Centipede" which won't run with my setup: PAL DC with 60Hz TV via RGB cable.
(game jumps back to the DC audio menu after displaying the SEGA logos)

I don't have the original .cdi image, so I can't use the available ppf-patch.

I analysed the ppf-patch, but it contains only the addresses and the new (changed) byte-values, not the original values, so I can't do a search for these strings and find out the corresponding addresses in my image.

Too bad the adrenalin patcher can't handle this problem with a generic search/fix as this patch seems more complex.
(the patcher found a 50/60 HZ patch location, but that didn't solve the problem and resulted in an even heavier crash / garbage on screen)

Can anyone provide the original and changed byte-values (preferable as a whole block) so I can do a search and replace operation on my image (or probably only in the 1st_read.bin file) ?

I think PAL Patcher works with this game.
Try it and tell me.

I'm afraid PAL Patcher can't handle it:

The following is directly from the readme file of PAL Patcher:

It doesn't work with these ones :
_ Centipede
_ Mortal Kombat Gold
_ Pop 'N Music
_ Skies Of Arcadia

P.S.:
Just look at the patch for the original .cdi to see how complex this patch is:
