Much of this data is too endangered to care about what someone said on their Geocities page 20+ years ago about rehosting their content. Archiving and ensuring its continued existence should be top priority.
funnily enough, a lot of Geocites sites and 90s-early 2000s GIFs are currently archived/available on various places. pretty sure 99% of these were uploaded without permission, yet nobody cares because the content is so old and even the creators themselves might like to see their work 'live on', so to speak.
time has a funny of way of turning things into pieces of history, as opposed to just 'intellectual property'. at this point, there are downloads for this game that are almost as old as i am.
I'm kinda in the same boat as SpaceShipRat & C-Rex. I've got a pretty good archive of my own, & I'm pretty sure there are some lost downloads in it, but I've always hesitated sharing it because of the permissions issue. And as unorganized as my archive is, I know there are a bunch of do not shares mixed in with the ones that don't say whether they can be shared or not.
you had some stuff that i was 10000% certain would be gone forever, that i was sure nobody but me would ever download. you of all people need to just unload that archive. i bet you probably have over half the missing files for every game in this series
