Relic change command

You can always create an anti patch by applying the ips to a clean rom, and then using Lunar ips to create a new ips file with the patched rom as the source and the clean rom as the modified file.

Will this fixed my crashed rom?

PowerPanda is a lot of things: a talented ROM hacker, a musician, a nice guy, but as far as I know he is not a Psychic... so you will have to try it and see for yourself if it fixes your crashed ROM.  
I thought the 'Summon This!' patch also included the aim fix...? Anyway, the anti-patch you make will need to be made without a header in mind, because that's how you patched it. OR, since it appears to be a ONE-byte change, just goto the one byte and change it back! Since you applied it without a header at first, it's going to be here:

Offset to change back: C25049
Change back to a $99 byte.

Hopefully that will fix your ROM. From now on, make a backup of your ROM as was suggested before doing anything that involves changing hex bytes! This includes using patches.
