Hi, I saw an 'NR Disc Verification Tool' on the internet (Just a floppy disc with a manual) and I was wondering if anyone knew what it actually did? Also, if anyone would care to explain exactly what an USB2EXI does (not just brief notions) I'd appreciate it Andy
NR verification tool verifies NR discs thus: NR disc verification tool -------------------------------------------------------------------------------- Description The NR disc verification tool is prepared to verify a GCM file data has been successfully burned in the NR disc. Since the NR disc verification program, named NR disc checker, is combined into "apploader.img", you can verify the NR disc without any other GameCube binaries. CRC compare mode The following steps describes how to verify the NR disc: On your PC, run makecrc.exe, under $DOLPHIN_ROOT/X86/bin, to generate "crc9056.dat" of the GCM file as below: % makecrc.exe input.gcm "crc9056.dat" will be generated under the current directory. Copy "crc9056.dat" file to your emulation DVD root directory. For your GDEV or DDH, prepare a blank 4Mbit memory card in slot B. % [od|load]run.bat format.elf # Use format.elf in SDK carddemo if necessary Save "crc9056.dat" to the blank 4Mbit memory card in slot B. % [od|load]run.bat save.elf -a crc9056.dat # Use save.elf in SDK carddemo For your NR Reader, insert the memory card in which you saved "crc9056.dat" file to the slot B. The slot A should be empty. Plug the controller for NR disc checker (distributed separately) to the controller port 4 of the NR Reader. Turn on the NR Reader without pressing any buttons on the controller for NR disc checker. On TV screen, green bar will be shown that indicates currently NR disc checker is running. The progress will be shown by lines of white dots. If any broken block will be found, a red dot will be shown instead of a white dot. If no error was found in the NR disc, a light blue bar will be shown under the white lines. Otherwise, red line(s) will be shown to indicate an error. You can identify the type of the error by counting the number of red lines as below: 1 red line: verify error (CRC mismatch) 2 red lines: card error 3 red lines: drive error Note the memory card must be a 4Mbit memory card and it must not contain other than "crc9056.dat". In addition, the company code and game code of the "crc9056.dat" file must be same as that of the GCM file. CRC generate mode You can also generate "crc9056.dat" file from your NR disc using the NR Reader only: For your GDEV or DDH, prepare a blank 4Mbit memory card in slot B. % [od|load]run.bat format.elf # Use format.elf in SDK carddemo if necessary For your NR Reader, insert the blank 4Mbit memory card to the slot B. The slot A should be empty. Plug the controller for NR disc checker (distributed separately) to the controller port 4 of the NR Reader. Turn on the NR Reader while pressing the Z button on the controller for NR disc checker until a yellow bar is shown on TV screen, which indicates currently NR disc saver is running. The progress will be shown by lines of white dots. If no error was occurred, a light blue bar will be shown under the white lines. Otherwise, red lines will be shown to indicate an error. You can identify the type of the error by counting the number of red lines as below: 2 red lines: card error 3 red lines: drive error Note the memory card must be a 4Mbit memory card and it must be a blank one!
