I think most of the source is now backed up, thanks to the archives that people sent me! Check the page here (as linked before): https://github.com/verge-rpg
Now we have source for Verge 1's June 1998 release, WinVerge, v2chr (distributed as zip-only, per request), Verge 2.01a, Verge 2.5, Winv2, Verge 2.5j / v2k+j, and a few revisions of 2.6. Also the Verge 3 source code was moved to the verge-rpg Github organization -- I kept a fork at my github account to preserve any existing outgoing links, however.
However, we're still missing source code to official Verge 2.5's VCC, and the source we currently have of WinV2 appears to be from unstable build, not a release version. It seems like Verge 2.6 revision 9 might be able to do a lot of the same things that 2.5 could do + some extensions added later.
If you have any copies of these missing source files, let me know and I can put them on the github repo. Also, if you made any tools for Verge-related stuff and want us to host it, let me know and please let me know any licensing/terms for distribution! For now the GH is for preserving the engine source code, we still need to figure out a different solution for demos and games.
If someone has a good idea for hosting our own organized file directory, maybe we can figure something out! For now we have the vrpg archives, but they're incomplete, and it would be nice to recover and preserve what we can in a collective effort.
Also, Andy (implicit_cast / thespeedbump) has been working on a WASM web player port of V1, and it's open to bug reports and contributions: https://github.com/andyfriesen/v1wasm -- it can sort of run parts of Sully so far, so that's exciting news!
