Just to let you know, the library you excluded (Audio Interface Library) was open-sourced in 2000.

http://www.thegleam.com/ke5fx/misc/AIL2.ZIP AIL Version 2, the complete Open Source release of the Miles Sound System Version 2 for DOS

@fpusoft it has been added to the LBA2 repo: https://github.com/2point21/lba2-classic/tree/main/LIB386/ail

Not sure the contents are exactly the same.
@sviannay @gwen-gg Can you confirm they have the same contents? or do we need to push the LBA1 AIL version eventually?

Contents in LBA2 aren't the same.
The AIL version released as open source is the same one used in LBA1.
Check the file "REL105.ZIP"

For the other AIL version for LBA2, maybe RAD Game Tools would agree to open source it since its over 20 years old.

Yes, I saw this was released in open-source (LBA1 version only), but after discussed, we decided to not include it as part of the LBA1 delivery as it can be retrieved from original one (I think it's better to not fork it). I hesitated to do so, but maybe we could just point to https://github.com/Tronix286/AIL2 (and/or from http://ke5fx.com/ you noticed, I didn't know this intersting link) or at least add a mention that an open-source version exists.

It might also work to add it as a git submodule pointing to https://github.com/Tronix286/AIL2 ? That way the code would still work as-is from a clone (with submodule init and update) but the code wouldn’t be duplicated/"forked" in this repository but rather still point to the upsteam.
