My use wasn't specifically Sega CD like you're doing here, but using that tool in combination with some others was the only way I could build full 1GB GD-ROM images in CDI format years ago.123 1942 1943: The Battle of Midway 3-D WorldRunner 8 Eyes A Abadox: The Deadly Inner War Addams Family Addams Family: Pugsley's Scavenger Hunt Adventure Island IV Adventures in Asmik Land Adventures in the Magic Kingdom Adventures of Bayou Billy Adventures of Lolo Adventures of Lolo 2 Adventures of Lolo 3 Adventures of Rad Gravity Airwolf Akira Alien 3 Ankoku Shinwa: The Dark Myth Antarctic Adventure Anticipation Archon: The Light and the Dark Arkanoid Armadillo Astyanax B Bad News Baseball Balloon Fight Banana Prince Baseball Stars Batman Returns Batman: Return of the Joker Batman: The Video Game Battle City Battletank Battletoads Battletoads / Double Dragon: The Ultimate Team Big Nose Freaks Out Bionic Commando Blades of Steel Blaster Master Bomberman Bomberman II Bonk's Adventure Boulder Dash Boy and His Blob - Trouble on Blobolonia Bram Stoker's Dracula Bubble Bobble Bucky O'Hare Bugs Bunny Birthday Blowout Bugs Bunny Crazy Castle Burai Fighter C Cabal Captain America and The Avengers Captain Tsubasa Vol. Not sure if that information is helpful at all since you already have a solution to your problem, but it was something I found helpful years ago. (If you used and of the available tools for building selfboot CDI's at the time, they would always fill the ECC and EDC sections with 00's, so the actual image wouldn't work in a Virtual Drive and you had to burn it and re-rip just for it to be usable in a virtual drive.) It was the only tool I found that could generate the EDC/ECC data, which was very useful for building selfboot images that you could mount in a virtual drive and use without burning them. It could convert between 2048, 2532, 2336 track formats, and would generate the proper EDC and ECC data if you converted from 2048 to one of the larger formats.

I used a freeware tool called ' CD Image Converter' (cic.exe) back during the Dreamcast days.

There is actually a program that can do this for you, and much more.
