Pointing & jumping to expanded data after FF/FFFF
« on: May 03, 2014, 11:28:49 PM »
I expanded my ROM to 6mb and am trying to get some song pointers, jump commands in events, LDA jumps, etc. to point to this new expanded data, and it is not working. I have data at 400000 and obviously I can't put G as a bank offset to jump to, so I point my pointer to 00 00 40 (400000), and this is not working. I can't seem to get anything to jump to this new data, but I've seen it done in other hacks that go to 400000 + past FF/FFFF.

Is there something else that I need to do in order to allow the game to recognize pointers & jumps to expanded data after 3FFFFF?

P.S. In case this helps or matters, I used HxD to expand my ROM, Lunar Expand gives me a "can't determine ROM memory map" error and won't do it. I hear that using HxD to expand the ROM works as good/the same as Lunar Expand.

Only once have I even tried to deal with a rom in the 6 megabyte range, and it did not go well. I guess check the internal header, see if everything is mapped correctly, run some traces with these other roms that do work, and go from there. One thing I am curious about though, is how you could've used up an entire megabyte with stuff just by expanding from 3 to 4. :omg:

119 bugs fixed and counting.

Thanks for the info!

As for your inquisition, besides some big events it was mostly lots of song data, expanded NPC sprites sheets, relocating item descriptions and some other misc. things with text routines, and now soon-to-be imported instruments. I've literally watched my banks get filled one by one and now I'm virtually out of space lol.
