Ahoy, Id like to "start working" with the CHD file of Rambo (Lindbergh) I unpacked it with chdman.exe to its (hopefully) original HDD img format. The header of the chd shows : MComprHD lzmazlibhuffflac, GDDD, CYLS 51647, HEADS:4, SECS: 32, BPS:512 So it probably IS the HDD version. Now I have no idea how to handle the resulting IMG file. There is nothing to see inside via hexediting and Id like to "work" with the original files of it. How to continue, to be able to work with the original files on it ? I hope Im at the right place for this question. Any reply is appreciated. p.s. I read MAME does support Rambo Arcade now. Can I just play this CHD file using MAME ?
it's an ISO file with probably multi track. cut the header somewhere to recognize as a standard ISO and mount with Daemon tools There's some su.dat for system update, a frontend, and the game data stored in disk0.img All files are unreadable. hopefully implement it's encryption module emulation soon by MAMEdev
Ahhh, so the "unpacked" IMG is the "final" ISO ? Ok, should be possible to find an entry point for the ISO then. Just stumbled across this. Very interesting indeed : https://github.com/mamedev/mame/blob/master/src/mame/drivers/lindbergh.c The resulting disk0.img and su.dat have to wait some time then for beeing explored ^^ p.s. I read in the other thread, that a guy managed to actually use the "Lindbergh Emulator" via Linux. (Wouldnt you still need the security chip anyway ? Or does this "emu" take care of decrypting ?) http://assemblergames.com/l/threads/anybody-know-anything-about-this-lindbergh-emulator.56931/ So maybe its possible to "read & copy" the files from there ? Maybe to an USB Stick ? :O
From what I understand, the way Lindbergh works is: a game dvd disc (your uncompressed chd image) is installed to the storage device of the unit (I have seen Lindbergh's with flash cards, also heard some have hard drives) then the game is only run off of that storage device allowing you to disconnect your disc drive (strangely enough Xbox 360 HD-DVD drives work great for installing Lindbergh games). I would imagine the emulator would have to do a similar function to what the real unit does and install the game to some sort of emulated storage device so it can run the game like the real system would. That's assuming the emulator is really as far advanced to run more games than After Burner Climax which is the only game I have seen screenshots of.
For RAMBO extracted chd: copy offset 0x398000 to the end of file in WinHAX into new file, result as a standard ISO, mount with daemon tool
Do you mean 3980000 ? Because 398000 is emtpy space. Either copying 398000 or 3980000 in either CHD or the unpacked IMG file to the end of the file, I dont get an iso. The "interesting" text starts around 003A1800... MKISOFS iso 9600 file + Rock Ridge... or did I missunderstand something here ?
It's 0x398000 in the extracted chd image After you copy the game iso, check 0x8001 "CD001 LINUX" mark and mount it
the keychip is used to decrypt the frontend.dat file to proper mounting script then ran on the system Emulation is not so complex, just need to emulate the baseboard and optionally other stuff like card reader. It's a linux system otherwise so... heh. I was giving jay some data in the past so he could test running in his linux with his emu and it worked pretty well.
I got myself a original Lindbergh RAMBO DVD now, just in case. Without the chip though. So "jays linux and emu" do require the chip ?
The emulator was never completed and only runs with already decrypted games in his linux environment.
It's not really a Lindbergh emulator, more of i/o board emulator, like those for Type-X or other PC-based arcade games.
exactly, but Lindbergh games are coded by bunch of apes. They require very specifiic drivers and kernel versions to work vanilla.
