Hey peeps let me know if you got this to work cause i had a problem with it. It might have been also cause i burned it to fast or just the procedure. Also it could be scramble problems i dont know both me and quzar had the problem so no clue.

Just use the unscrambled bin with SBInducer - put with IP.BIN & BIOS in the /Inducer/ dir and execute SBInducr's SBI2Boot option iirc ...or just use a decent scramble app. ;)

This might also work with Lying Wake's aka fackue's great NeoGeoCD DC Selfboot app.

[Eric]

thanks for the info i might start using SBI soon or start using the new Selfboot program as i am still stuck in the year 2001

Soon I will upload SBI pack, wait a while.

excellent work :)

[fackue]

I knew you were up to something, but that's a lot you did there. Great stuff.

Oh, BTW, it should work (the selfbooter) if all that's needed is the 512 byte (KB? I can't remeber) BIOS that's named neocd.bin and it's still in the root.

EDIT: The "What's new" in that link above is not correct.

[fackue]

Scramble it with 1st_read.bin file checker. This is definately a correctly scrambled BIN. I havn't tested it though.

And you can use NeoCD Selfbooter to make a DiscJuggler image of it.

I HAVE A PROBLEM :(
I put 1_stread.bin scrambled and ip.bin, and bios file "neocd.bin" (same bios wich i have used in old versions), when start the emu, and put the CDROM of a game, appear "BIOS INVALID" o_o and don't work.

[quzar]

The link to the download is dead.

[quzar]

The bin has been fixed and re-uploaded.

Thank you Quzar! I made a nice .sbi of it and it works great :D
I put it here as the link from M@jk still contains the first release:
http://membres.lycos.fr/danyredrum/neodc.sbi

ps: I think the link here http://www.dcemu.co.uk/neodc.shtml has still the bad release as the .bin has a size of 729KB and is dated from 10/04
