    Testing OK! But the title screen keeps in 4:3, gameplay keeps in 16:9.

    So the code works in-game on a real Dreamcast? Does it have the geometry clipping fix applied?

    My friend Ziming asked me to post this one too. He is live streaming the hacked game right now. Check it out here if you guys see it in time, Otherwise it will be archived for later viewing.



    Note: It is running from a GDEmu.

    That's strange, my testing is only 1st disc's title screen in 4:3, the others in 16:9,
    I used pal 99mins English translation version, is that right, Esppiral?

    Yes, it really works and has the geometry clipping fix applied, but my testing is only
    1st disc's title screen in 4:3, the beginning animation has a little flaw, the others are all OK, the gameplay is all in 16:9, so enjoy it~

    Could Marvel vs Capcom 2 NTSC-U receive a widescreen iso patch?
    The pal one has an ISO patch but not the NTSC-U one.
    Thank you.

    Yes, I all tested them, they are in pal version, (Shenmue2 full English 99mins pal) Shenmue1 widescreen almost perfectly worked on a real dreamcast, and Shenmue2 widescreen did it, too. ( Just don't care about the 1st disc's title screen of Shenmue2, and the little flaw of the 1st disc's beginning animation. ) So these hex patches really made Shenmue 1&2 become 16:9 in widescreen on a real dreamcast, "without" using the codebreaker CD, thanks Esppiral once again.

    The code also works fine on Shenmue Undub.

    The Code for Legacy of Kain: Soul Reaver works for the enviroments, but Raziel still looks stretched. Is there any way to fix this? Thanks!

    Soul reaver consist of 3 codes
    Environments
    Character
    And render fix

    Depending on the cheat device you use it will fail to apply all of them I think code braker had problems while Action replay worked flawlessly or the other way around lol

    For anyone interested, I work on the dreamcast emulator redream (https://github.com/inolen/redream) and this week I worked on adding support for automatically patching games using the direct 1ST_READ.BIN patches Esppiral has started creating (thanks for the awesome work).

    The format of the patches looks like:
    https://github.com/inolen/redream/blob/master/src/guest/gdrom/patch.inc

    I've added in a few for now, but would greatly appreciate the help if anyone would like to contribute more.

    Edit: It would be really cool to patch the bios as well.
