'''PT_SCE_MODULE_PARAM (PS4)'''
This segment contains a single C struct. It appears instead of PT_SCE_PROCESS_PARAM if the ELF file was compiled to be a library. Like PT_SCE_PROCESS_PARAM, the .data segment contains it and it is always at offset 0.
<source lang="c">
struct SceModuleParamBase {
    // current size of the struct this version
    uint64_t size;
    // magic bytes
    uint32_t magic; // 0x3c13f4bf
    // current version of the struct format used
    uint32_t version;
    // for example: 0x0803_0001 for firmware version 8.03
    uint32_t sdk_version;
}
</source>
The struct is the base or head of the actual struct used. The above fields are always present and their offsets do not change between versions.
Fields whose name are of the form: unk_0x[0-9 aA-fF], are unknown fields whose offset is in the name, e.g. unk_0x18 is at offset 0x18.<source lang="c">
// checked FW 2.xx-7.00
// FW < 2.00 files do not have a PT_SCE_MODULE_PARAM segment, unchecked 7.00 < FW < 7.55
struct SceModuleParamV1 {
    uint64_t size; // 0x18
    uint32_t magic; // 0x3c13f4bf
    uint32_t version; // 1 for V1
    uint32_t sdk_version;
}
// checked 7.55-9.00, unchecked FW > 10.50 and 7.00 < FW < 7.55
struct SceModuleParamV2 {
    uint64_t size; // 0x20
    uint32_t magic; // 0x3c13f4bf
    uint32_t version; // 2 for V2
    uint32_t sdk_version;
    uint64_t unk_0x18;
