It is impossible to add multiple disc versions with the same serial to the library due to games.yml format

[13xforever]

Quick summary

It is impossible to add multiple disc dumps with the same serial to the library.

Details

Currently, games.yml maps exactly one serial to one disc dump path.
This is suboptimal for several scenarios:

• Having original game disc, and multi-game re-release where serials can match
• Having the original game dump and modified versions (fan translations, undubs, gameplay mods, etc)

Then how do you know which of these games to load if you boot from title id (which we do a lot)

idk what's the best solution in currently implemented architecture

Purely from user experience perspective you can do a stack of paths with the same id and switch whatever copy on top; you can deprecate launch with id and use full path to sbf/eboot.bin, like most emulators do

All of the solutions I can think of will have some drawbacks, but the fact is it is absolutely impossible to have more than one version of the game in the library without editing the serial (which has its own issues)
