Finally managed to build the improved version of Hugohunt (remember?). It's an 8k F8 game now, as Thomas Jentzsch suggested, so it may contain up to 14 mazes. Stefan - the originator himself - has created many of the new levels, for example:
I'm still doing a bit of testing on the final version, but I've added a PAL and a NTSC Demo version; both contain 4 mazes.
The F8 game has been tested on a 2600 junior PAL with a soldered F8-cartridge
using this schematics and it works fine.
Any volunteers to test the NTSC version (some had promised to...)?
