terrible idea for a gimmick hacking tool
-
@Tau yeah but only so much. my system isn't powerful enough/this emulator isn't light enough that I can go at 100x speed, for example. I think I'm getting between 2-3x speed at the moment.

ARG. injection attempts have revealed that my partial decode script is using the right stride for the data files, but I misjudged the start and end point. So I need translate all my logic to shift all variables 16 bytes to the left. gah
-
actually I may not need that. I may never touch this script again, so I'm going to just note this and try to ignore it.
-
okay so the extraction is taking about 70 seconds per portrait, so searching the 8-bit space (and I PRAY it is 8-bit!) will take 70*256 seconds, or... see you in five hours!
(it'll hopefully speed up when I finish reencoding my roommate's copy of Armageddon (1998) to be videocd quality -
I accidentally encoded Armageddon to 24:5 ratio which is less than watchable so I'm having to restart the encode
-
I'm now considering hacking the ROM so that the opening movie is shorter
-
I figured out how to optimize the emulator (turning off the display!) and got it down to 35s.
35*256=2 and a half hours -
I found part of the movie player and hacked it to, uh, not work
-
it just hangs forever
-
oh hey this stack trace goes through the VRAM.
I pray to god that's a bug in the stack tracing and this code isn't jumping in and out of the VRAM
-
got it.
to patch out the opening movie, change offset 0x5EF8F in the 10729BD884F8FDCA7A310B6D606C52E46657AA48 gba rom from 0xD0 to 0xE0. -
it took an hour and 20 minutes to figure out which two bits to change in the ROM

it now takes 7 seconds per character
so it can finish in 21 minutesbut note: if I'd just let it run, it would have just about finished by now on the slow route
-
dang it. it turns out characters have sub-expressions too
-
it turns out if you go above the maximum expression on character 1, you get to the expressions of character 2
so I just set it to character 0 and I'm iterating through all the expressions, since I can hit every expression on every character that way

@foone It absolutely would not surprise me. How many versions of the ROM can you run simultaneously? Or do you do it one by one?
-

@gregly I do it one by one for simplicity
-
they use 241 of the 256 slots!

@foone Sensible. I just had this image in my mind of a 16x16 grid of emulators all running slightly different versions of a ROM like some sort of quantum alternate timeline viewer.

@gregly I should try that sometime and see if it's any faster!
