>>56780792Okay, this is a pain, but it won't show sprites that end in z or another letter by default.
What you have to do is while adding drive sprites is to make 2 copies, 1 you add as normal, and the 2nd set yo remove the Z at the end and add those. if there are any conflicting one (and there will be) don't override. go back into the custom battle folder and delete any remaining sprites that weren't sorted into the proper folders.
For example
>>56780703 is 73.155z, so you need to change it to 73.155 for it to show up by default, BUT you also want to keep 73.155z because if they ever add a 73.155, it will override the one you have.
