    The new hacked file works great.

    Though the button combo is Start + (B) to toggle between widescreen or 4:3

    Awesome, great work! for Sega Rally I used the full version, and for some reason I couldn't be 100% if the wheels looked round or oval

    Is the widescreen correctly 16:9?

    No it's set to 43800000 (000008043) but it's easily changed to 43700000 (000007043) for proper 16:9.

    How possible would it be to do the official Bleem games? I was always kind of bummed out that there were no Gameshark type cheats for those games. Might be impossible since the emulator disc loads into memory before the game?

    Main problem as far as CB code goes is that BC! doesn't work with emulators, so it's hard to debug and figure out.

    True. Is that how people just do it now or what? I know when I had an old PSX Gameshark Pro I had a button on the side of it where it would bring up a nice OSD that let you hack games in real time. Obviously that is an exception to console hacking, but how did people make codes for Dreamcast back in the day before emulators? I know on other consoles you could connect them to PC and figure it out that way. Did people use the serial cable or something?

    Hello guys,

    thanks to all for the work and effort. It would be great to put all working codes in the first post otherwise you need to go through all pages to find a specific code.

    I am also looking for codes for following games:

    All PAL versions except D2:

    MetroPolis Street Racer
    Shadow Man
    Sonic Adventure 1 &2
    24 hours of Le Mans
    18 Wheeler
    F335 Challenge
    Resident Evil Code Veronica
    Evil Twin
    Soul Reaver
    D2
    Sega GT
    Crazy Taxi 1 & 2
    Skies of Arcadia
    Resident evil 2 -> I think this one is not possible due to pre-rendered backgrounds
    headhunter
    Berserk
    Evil Twin
    Tony Hawk 1 & 2
    Ecco
    Jet Set Radio
    Sega Extreme Sports
    The Nomad Soul
    Dino Crisis

    Would be awesome if someone can dig in and find out the codes for the listed games :) Escpecially for games like Metro Polis Street Racer, Shadow Man, Sould Reaver, Skies of Arcadia, Headhunter, Jet Set Radio etc.

    To compile SH-4 assembly code, I read that you need "sh-elf-as" from the "SH4 toolchain", which can be downloaded e.g. from here: GCC 4.9.1 Newlib 2.0.0

    I've tried all of them with no luck so far, If only more people would be looking into it...maybe I am missing something.

    Metropolis street racing
    Sega Xtreme sports
    Jet set Radio
    Sonic Adventure 2
    Soul reaver
    Shadowman
    Ecco the Dolphin
    Evil twin
    18 wheeler
    Evil Twin

    I've tried all those among others with no luck ; (

    The more people involved the better chance to find the addresses.

    I would really like to help you but I do need a short guide to get started. I guess I need one of the dreamcast emulators, some hex editor and just try & error to find the correct code?

    A kind of wiki would be good, we will be able to add, edit or remove widescreen codes.

    According to a google search, MSR is one of the games that already has Widescreen support. You unlock it by beating the game.
    It may be beneficial to see how that functionality works.
