[ASM & Hex] porting scripting commands from EM to FR?

[tkim]

Is it possible to port a script command that only exists in EM to FR? I've gone as far as repointing the commands table (0x15F9B4) and added an entry (command 0xD6) that is a pointer to my fadescreen3 routine. I tested it and it did nothing ingame, so I'm thinking there is a limiter or a routine that does not recognize 0xD6. I also tried replacing the fadescreen pointer to my routine just for further testing- it allowed the script to continue running but again, did nothing.

There are multiple limiters. They basically are just a pointer to the last command in the script command table. You'd have to change the pointers at 08069AA0, 08069B20, 08069B7C to point to a nop at end of your repointed table (they currently point to 0815FD08).
