    Oh I see now! I wasn't aware that you could transfer CB code to Hex code. Is it possible transfer Hex code to CB code? Just wondering.

    Thank you for the explanation, I might give it a try to see if I can find a few.
    This has been very helpful, I've tried to find codes for the games you shared a while back with no luck.
    Here you are knocking em out like it is knowone's business. :)

    Blessed thy kind soul sir!

    yes, it's possible
    but for the back transformation it is necessary to know the SH4 assembler

    You find them fast.

    Megavolt, could you get hex code, and if it is possible to repair the objective frame?

    Has anyone tried finding a widescreen code for Marvel vs Capcom (any region). I tried but no luck finding anything. It might be because it is a pure 2d game. I am correct?

    Yep, those kind of pure 2D games would need the sprites doubled or something I believe. I think MVC2 could work since it has 3D backgrounds. I have been hoping for years Last Blade 2 Heart of the Samurai would be able to be patched for VGA by Japanesecake but he said the same thing to me, it would need to have the sprites doubled to display correctly in 480p since it is a 240p game at least that is how I understood it. Please somebody correct me if I am wrong here.

    I have done a try on shadow man :

    And I have find this from @Esppiral :
    Shadow Man EU : 022C03F4 -> 3F400000
    Shadow Man EU(cropped) 022C03F8 -> 44558000

    From the @Esppiral codes, I never find a 0x022C03F4 in each bin of the gdi... and the other change nothing unfortunnately.

    the @megavolt85 first works uncredibly well ! But you have some disgracious clipping it's why both guys suggest a cropped code but the second one from megavolt is closer to the character but the picture is very stress and for example the pink life balls are very oval and the viewfinder is very on the right to the ennemi we aim for...

    what the 0x8055 from the second megavolt code change exactly ? It's possible to cropped the camera without changing the proportion of the picture ?

    thanks, I'll try to post some pictures soon.

    Here an old message but there is no hex patch for 60 FPS during battle for grandia II (JAP or PAL)

    I try the widescreen patch made by megavolt and it looks incredible great !

    But now do you have a 60FPS patch in hex for battle in pal version ?
    How is it possible to "convert" codebreaker to hex ?

    Here the video made by @Esppiral :


    Thanks for your help :)

    He's back!

    Could you possibly do a widescreen patch for Cosmic Smash?
