Hey dudes!!!
I recently bought a NES from a flea-market.
It included some games and gamegenie with a loose SLROM board on it.
So when I got home, I wanted to play the nes.
Mario1+Duckhunt played fine, Track and Field 2 played fine, the Pirate Multicart that came with it played fine, so here I go...the SLROM board.
first NOTHING!
Cleaned the contact of both the board and the game genie....it kind of worked. artifacts on screen but the game genie booted. I didn't put in any codes and pressed start.
it's DOUBLE DRAGON!
Cleaned the contacts some more.....still weird screen, so I couldn't wait to take the roms off the board and take em to some radio amatuer that lives here.
After getting over there and looking up the pinouts of the chips he rewired a romsocket and placed that on a rom socket in his programmer.
He actually dumped the full contents of both PRG and CHR rom and with UCON I converted it to iNES format to see if it worked.
Nintendulator crashed and I looked at the HEADER.....it had a mapper0 header, so I changed it by looking at a verified dump of double dragon.
It works!!
But I noticed some difference in the titlescreen:
after starting the game, I noticed another difference at the bottom of the screen:
When I wanted to pause the game I skipped a scene/stage.....
is this a hack of some sort? or is this a beta/review cartridge ?
