    Thank you Espirral for these lovely christmas presents!
    Merry Christmas to all Assembler members
    As for Rainbow Cotton, since a big complaint about the original game is that the Cotton herself is always obstructing the view, would it be possible to fix that a little bit by perhaps putting the FOV back a little bit?
    So that Cotton herself will be smaller and you are able to look past her a little bit.
    Or all the way in the front so it almost is like a first person view where you don't see cotton at all (or perhaps a little bit, like only the front of her broom stick).
    Perhaps all these years later, the game can actually be fixed so that it is more playable and more fun. This game is so beautiful. Those trains remind me of Gunbird

    I tested this code on an actual Dreamcast and got a blank screen.

    =(

    Btw, would it be possible to patch Rez with the 60 FPS fix (similar to how you patched Grandia II) so the Codebreaker code won't be necessary?

    8C3D67Ex for you x it's 7, you must have 0, 4, 8 or C
    You have to insert a 0x00 in order to move your pointer in the good alignement.

    Thank you, what's the best way to learn this stuff?

    Stuff as in reading the hex codes and knowing how it applies to the aspect ratio.

    For alignement a gentleman from an other forum took the time to explain me. And I'm not sure to all understand correctly. It at works for you ?
    I'm looking for learn every day and unfortunately I don't have any link for sharing...

    You have to use a software like IDA for reading the hex code from SH4. I don't neither how it works exactly.

    Hello all! First of all thanks to everyone for the amazing work being done here!!
    I enjoy Sega Bass Fishing in 16:9 with my fishing controller on my 65inch flat screen, AMAZING!!! Nothing is better than a cold beer and Bass Fishing after a long day of work haha.
    Another amazing game that nobody talks about stragely is Sega Bass Fishing 2...

    Question: Can somebody make the codes for the JP release of Sega Bass Fishing 2?
    Or are they written somewhere? I looked for hours but did not find any codes for this game :(
