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 | bfevfl uses pointers very heavily to refer to strings, to other sections, etc. All pointers are always 64 bit long -- since the same format is used on the Switch which is a 64 bit platform. They must be present in the [[#Relocation table]] if the file is to be loaded correctly by the official bfevfl code. | ||
As a direct consequence, most sections don't have any fixed order. Therefore, this article will only document the data structures and mention the order Nintendo places sections in. For more details, it is recommended to look at the [https://github.com/leoetlino/evfl <code>evfl</code> library] directly. | |||
