Probably not (easily) possible, but it would be interesting if existing GEOS applications could be ported to use GUI, instead of writing them from scratch
I've never thought about fully-blown Wolfenstein 3D clone on A8. But simple escape-the-maze type of game based on this would be possible and fun. Just some more levels and few ideas to make the gameplay of reaching the exit more attractive (hidden places, points).
Yeah, I used to do this with Project M and IK+ as well... Sad side is all those are just a demos after decade(s), but they show A8 powers as only few do.
It must be something in the forum engine: indeed the file can be downloaded from the original message, but can't be downloaded from attachments-list (not with 'save as', not with simple click - in the end it's forum that says it can't be located ).
From what I've read at the time it appeared, it's not the same, but a new project developed by Candle. It's quite similiar to Turbo 1050 with its limited functionality (e.g. no track buffering) and nothing very interesting

Yes, that's exactly the case, I just wanted to experiment with S-Video via SCART (to have zero artifacts), but it's not critical to have it, since composite (Atari) / RGB (Amiga) are looking just great on it.
