Hello, first of all, great job, thank you for this hack ^^.
I dunno if somebody has already told you it, but when you started the game on a linker (after SRAM pacthing to avoid the Flash savetype problem with the white screen), the intro and the main screen are really... buggy.
When you press start during the intro, you get a white screen, and keep earing the intro sound until the end, then start screen appear, completely deformed (but you stille have sound and the Crono title).
You can press start, and then the game keep going normally (or at least at the beginning).
So, nothing really important, but I just want to tell you. ^^
I can't take a photo right now, sorry.
