Research direction
Start by comparing the attached logs for Sega Classics Collection, The Fairly Oddparents - Shadow Showdown, and GTA Liberty City Stories, focusing on the reported syscall 0x5b and whether syscall 0x6 (LoadExecPS2) is needed for launching collection games. Done means the required syscall behavior is supported for these games; the issue leaves the exact implementation entry points unspecified.

Description
According to the logs of Grand Theft Auto Liberty City Stories (SLUS 21423), Sega Classics Collection (SLES 53461) and The Fairly Oddparents - Shadow Showdown (SLUS 20880)
SEGA_CLASSICS_COLLECTION_LOG.txt
FAIRLY_ODDPARENTS_SHADOW_SHOWDOWN_LOG.txt
These three games requires the 0x5b Syscall.
with Sega classics collection (and i have the suspicion that maybe with also Sonic Gems Collection, Metal Slug anthology and Sonic Mega collection plus are the same way just on the way those games are like launchers...) Might also need The 0x6 that it's the LoadExecPS2 because Every game inside the collection is another .elf beside the main .elf
i want to try and implement these myself but in the meantime these ones are the ones that these games needs.
