bfevfl is a little endian format, so values are stored in little endian even on Wii U. | |||
bfevfl uses pointers very heavily. All pointers are always 64 bit long -- since the same format is used on the Switch which is a 64 bit platform -- and must be present in the [[#Relocation table]]. | |||
There is no fixed order for most sections. Therefore, this article will only document the data structures and the most common order. For more details, it is recommended to look at the [https://github.com/leoetlino/evfl <code>evfl</code> library] directly. | |||
