Lately I've been thinking of perhaps reviving a mod I started and promptly abandoned a few years ago. Among other things, I remember being quite disappointed that while Portal contains virtually all of HL2's assets and entities "under the hood", most/many of them are nonfunctional, such as weapons missing sounds and dealing no damage.

Since both their code has since been published by Valve and source mods, such as the whatsitcalled map base something mod (the one RTSL use for their contests) are A Thing™ now, I wondered: is there any mod that properly reintegrates HL2 code with Portal, to be used as an improved and up-to-date basis for Portal mods? I googled around but could find no such thing.

If anyone has some pointers, I'd be most grateful.
