Megaman X Collection (NTSC-U) [GXGE08]

[Vague Rant]

NEW EDIT: Blurgh, meh. This seems stable enough for gameplay, so I guess I'm going with it:

I'm not sure if anything else reads from that 32-bit address though. I've done what's within my ability, so that's the last code I can offer.

OLD EDIT: This started out as a request topic, but I mostly have what I need, so I guess I'd just like some suggestions for stability. I found the memory address the menu checks for whether or not to display the unlockable Mega Man Battle & Chase, but I don't want to just force it always on since it could potentially interfere with the various subgames. However, the code I'm using only seems to work when I actually apply it by USB Gecko, and I don't understand why.

It checks for the ASM that writes 0 to memory, and forces it to write 1 instead. But loading the code via traditional means, I don't see Battle & Chase. Any thoughts?

For posterity, below is the topic as originally posted.

There are plenty of "infinite health" codes, etc. around the web, but unfortunately none to access the unlockable content (the image/music gallery, and the full port of Mega Man Battle & Chase). These are all unlocked for various in-game accomplishments--in particular, Battle & Chase is for beating X1, X2 and X3. My rudimentary hacking skills are of the "greater than/less than" variety, so while I did trawl through memory for a while, I wasn't able to find anything more substantial than a switch to turn off the locked "static" animation on the Battle & Chase entry in the menu:

Pretty unspectacular, I know. Hopefully someone with more talent can do better. Either way, thanks for reading.

EDIT: Stepping with the disassembler eventually led me to this code, a nop which causes the screenshots to appear instead of static. It still doesn't run, but maybe it can help someone else figure out how it works:
